29. A method as claimed in claim 22, wherein said step of determining said first and second positions includes the steps of receiving and decoding the P code from said geopositioning system. The aiming circle is a set distance from the line of guns. Notable examples of Soviet howitzers include the M-10, M-30 and D-1. fabric guide . The GPS satellites provide data in one of two coded forms: a very accurate P Code which is classified and limited to the US and selected Allies, and the CA code available for all civilian applications. In any event, laser ring gyros are basically quite expensive and delicate. The distances between guns are the second side, with each gun different, but known. Hopefully it will help you with your scale model builds.Don't forget to subscribe and there's more content at http://www.scalewarmachines.com.EnjoyPlease visit us:http://www.scalewarmachines.comOr give us a like:https://www.facebook.com/ScaleWarMachinesA +1:http://plus.google.com/b/101900881104831985371/101900881104831985371/postsOr join our Google+ Community:http://plus.google.com/communities/100585513617534645303We're also on Twitter:http://www.twitter.com/ScaleWarMachineCopyright 2017 Scale War Machines All Rights Reserved Our Amazing Products are Perfect for Anyone Looking to . Size Guide . Nimbus INFINITY - Nimbus INFINITYA direct sequel to Project Nimbus, Nimbus INFINITY is a high-speed mecha combat game. The principles, preferred embodiments, and modes of operation of the present invention have been described in the foregoing specification in terms of necessary modifications to existing equipment. Vienna, Verlag Militaria, 2007. Particular utility can be obtained by placing the aiming hardware of the present invention together with the gunner inside a crew compartment that is protected from chemical, biological and radioactive (CBR) contaminates. All these answers address the big picture of how the artillery works, but not how to aim the gun itself. Semi-permanent "firebases" thus are not practical against modern counter battery measures. The right is short and stout and slightly more vertical while the left is long and thin and slightly more obtuse. No known system for aiming artillery that uses GPS accommodates all these factors with tactical practicality. A method and apparatus for aiming artillery by incorporating the GPS NAVSTAR system directly into a mobile artillery unit such as a howitzer. The 0-3200 of the aiming circle line is laid on the howitzer- target azimuth and the howitzers are laid parallel as in paragraph 98. means for supplying said distance to said first RPU at said first GPS ground station. The final aiming of the gun involves transferring the azimuthal coordinates to the artillery piece by using the panoramic sight to align the mil scale on a GPS station rather than an aiming stake. supplying said distance to said first RPU at said first GPS ground station. Another proposal is to deploy two GPS antenna units along the barrel of the howitzer. Ohand yes, it's rifled, and yes it's necessary for accuracy at that distance. [19], In 1859, the armies of Europe (including those that had recently adopted gun-howitzers) began to rearm field batteries with rifled field guns. It is to be appreciated from the foregoing discussion that the aiming procedure of the present invention is simple, quick and accurate. However, the howitzer is used by firing indirect fire, NOT directly at the enemy. howitzer clothing is designed in the usa. The most famous of these "gun-howitzers" was the Napoleon 12-pounder, a weapon of French design that was extensively used in the American Civil War. This is a free reference film from http://www.scalewarmachines.com. Heinrich Rohne, "Zur Geschichte der schweren Feldhaubitze", Ildefonse Fav, Rsum des progrs de lartillerie depuis lanne 1800 jusqua lanne 1853, in, Ortner, M. Christian. Performance MeasuresGONO-GO1. A howitzer is a short cannon, placed at a steep angle of descent, used to fire at relatively high trajectories. Trachea, Main Stem Bronchi, and Carina. PADS are similar to inertial coupled systems. In contrast, making inertial systems and PADS more accurate will also make them more complex and expensive. An apparatus as claimed in claim 1, wherein said first and second ground stations receive the CA code from the geopositioning system. Lightboxes. The heaviest (later called "medium siege howitzers") had calibers between 200mm and 220mm and fired shells that weighed about 100 kilograms (220 pounds). Generally, the accuracy of the angle of the base line formed between the ground stations and a fixed reference direction must be known within an uncertainty of a mil as viewed on the mil scale. Some iterations of this task should be performed in MOPP 4. Eventually a constellation of at least eighteen satellites should transmit ephemeral data to enable GPS receivers on ships, planes, land vehicles or infantrymen to quickly and accurately determine to within meters their exact terrestrial position in three dimensions. Standard: Lay the howitzer for initial direction without an aiming circle using the pantel so that all howitzers in the battery are So to actually answer the OP, using the the M777, each round will be off in range about 0.3% of the total distance fired and off in deflection (left or right of impact) 1m/per Km. The howitzermust be in position with the tube at lay elevation and within 50 mils of the azimuth of fire. Moreover, their greater range let them create many of the same effects (such as firing over low walls) that previously required the sharply curved trajectories of smoothbore field howitzers. The distance is typically determined with the aid of an infrared or laser range finder, or by traditional survey estimation. Hence, PADS are normally mounted on separate survey vehicles where they receive fewer shocks since a driver can choose the best route for surveying rather than the best route for driving a howitzer to its assigned position. The English word howitzer comes from the Czech word houfnice,[1][2][3] from houf, 'crowd',[4][5][6] and houf is in turn a borrowing from the Middle High German word Hfe or Houfe (modern German Haufen), meaning 'crowd, throng'. This aiming circle/sight was the primary system for laying Foot Artillery Howitzers and Guns from 1893 through approximately 1902. Finally, the aiming apparatus of the present invention provides its own back up system since the modified mil scale is fully compatible with other aiming techniques. Press question mark to learn the rest of the keyboard shortcuts. 11. 13. Howitzers are mounted on tracks so as to bash through almost anything. Moreover, each PAD may cost as much as quarter million dollars each which make PADS uneconomical to integrate into a combat vehicle. This was a product of technical advances such as the French invention of autofrettage just before World War I, which led to stronger and lighter barrels, the use of cut-off gear to control recoil length depending on firing elevation angle, and the invention of muzzle brakes to reduce recoil forces. Available for both RF and RM licensing. fm 6-50, mcwp 3-1.6.23 chapter 4 laying the battery, and reporting the aiming . The normal carinal angle is. AIMING CIRCLE M2 W/E (1290-00-314-0008) AND M2A2 W/E (1290-01-067-0687) TM 9-1290-262-10, 15 April 1981, is changed as follows: 1. 10. It is not surprising, therefore, that several concepts have been advanced for using GPS to direct artillery fire. I will . The apparatus includes a video camera for manually removably attaching to the pantel and receiving the sight picture in the pantel or displaying a sight picture in a pantel eyepiece, a pantel deflection setting encoder for . The howitzer crew then aims the gun in the right direction by turning left or right to the "deflection" and up or down to the "elevation" they've been told and leveling bubbles on the gunner's sight so the gun shoots in the right direction. Cannons fire at low angles of elevation (<45), and the projectile lands much faster at its target than it would in the case of a mortar. You plug it all into the FDC computer and then the howitzers get fire missions for number of rounds, type of round, fuze delay, etc. Thus, while howitzer gunnery was more complicated than the technique of employing mortars, the howitzer was an inherently more flexible weapon that could fire its projectiles along a wide range of trajectories. [12], The current U.S. military doctrine defines howitzers as any cannon artillery capable of both high-angle (45 to 90 elevation) and low-angle (0 to 45 elevation) fire; guns are defined as being only capable of low-angle fire (0 to 45 elevation); and mortars are defined as being only capable of high-angle fire (45 to 90 elevation). The first day Sgt. 1. Though usually fired at the relatively high angles of fire used by contemporary siege howitzers, these field howitzers were rarely defined by this capability. Disengaging from battle is clearly undesirable. 2, the preferred embodiment of the present invention obtains maximum dispersion of the battery by moving the pairs of howitzers out of optical sight of another pair. Preferably the second GPS station also comprises a howitzer so that the artillery battery disperses in tactically preferred groups of two howitzers each. This technique involved deploying artillery in batteries positioned behind friendly lines under cover of hills, woods, and any other obstruction that hid the battery. As shown in FIG. Alternately, the apparatus may be adapted to the special requirements of the particular system. 17. 20. The positioning of the guns was then correlated to the coordinates of the target as derived from a map or observers. The hardware that is added, a modified mil scale, GPS receiver and positioning computer, comprise relatively simple and reliable components that do not require much periodic maintenance or realignment on the battlefield. One advantage of the present invention is that the panoramic sight is modified only to the extent necessary to enable the gunner to locate and align the mil scale off the second GPS ground station. This type of system is similar to the LORAN or SHORAN systems currently used to determine the location of ships and planes. An M109 Paladin 155 mm howitzer made history recently by shooting down a fast-moving maneuvering cruise missile with a "hypervelocity projectile" able to travel at speeds up to Mach 5 . transferring said second azimuthal angle to the second piece of artillery by aligning said first GPS ground station at said second azimuthal angle. The math is a bitch but no one really does it with pen and paper unless things have gone to hell and at that point you probably aren't getting orders for missions from Divarty, you're probably putting your tubes on the deck for direct fire missions against some assholes who think they can just drive up and kill you. Since World War II, most of the artillery pieces adopted by armies for attacking targets on land have combined the traditional characteristics of guns and howitzershigh muzzle velocity, long barrels, long range, multiple charges and maximum elevation angles greater than 45 degrees. To setup the aiming circle ( Figure 4-4 ), do the following actions: (1) Unstrap the legs of the tripod, loosen the leg clamp thumbscrews, and extend the legs to the desired length. FIG. Yet another class of positioning system is the Position and Azimuth Determining System (PADS) adopted by the armies of several nations including those of the United States and United Kingdom. The first steps in aligning PADS are unevolved from common survey methods. Rather, the GPS receivers merely eliminate the time consuming initial steps in surveying the battery positions. Hope all that long-winded BS helps, if it doesn't lemme know and I can try to be clearer. When only one aiming circle is available, it is used at the howitzer position. The invention that is intended to be protected herein should not, however, be construed as limited to the particular implementations described, as these are to be regarded as illustrative rather than restrictive. The 1/92nd Field Artillery Association - Vietnam. Other AGPS are "coupled" to an axle of the artillery piece so as to measure how far the gun moves. It is therefore to be appreciated that the accuracy of the present invention is not limited by the uncertainty in the position of the GPS ground stations but by the magnitude of nonreciprocal error in the position determined by GPS ground stations in close geographic proximity and by the base line distance separating the ground stations. elevation, a distant aiming point (DAP), an M2 compass, a gunner's reference card, and a command to lay the weapon. How exactly do they aim them. BRIEF SOLDIER: Tell the Soldier to lay the howitzer by using the aiming point deflectionmethod, the M2-compass method, and the howitzer back-lay method. Furthermore, the artillery battery must quickly resume firing at a new location to deliver enough ordnance to be effective. Many, for the sake of simplicity and rapidity of fire, dispensed with adjustable propellant charges. People Circle. [15], In the middle of the 18th century, a number of European armies began to introduce howitzers that were mobile enough to accompany armies in the field. In a pinch you could lay a battery of guns using the stars. Thus, the present invention contemplates an application of GPS to the deployment of artillery that accommodates existing tactical practice, improves speed and accuracy while also providing a backup aiming method that is consistent with present equipment. 25. Second, the present invention requires adding to a howitzer only a few additional elements of aiming hardware. The accuracy of an inertial gyro system is limited, however, because of inherent inaccuracies in the inertial gyro as well as by errors introduced by slippage of the wheel caused by, for example, traveling over snow, mud, or sand. School No School; Course Title AA 1; Uploaded By BailiffMole197. It was built 23 years ago. tread circle. The 1/92nd unit history is a work in progress.Historical documents and information keep surfacing. The German Foot Artillery 0-5800 scale is expressed (simplified) from the 0-5760 scale, which is graduated in a scale of one sixteenth of a degree. 2 is a schematic representation of an artillery battery using the present invention in combat. In the past . Alternately, the computer can orient the scale if the sight is designed to incorporate necessary encoders. The process was then done over again. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Soviet doctrine was remarkably different from the German doctrine of Blitzkrieg and called for a far more extensive use of artillery. Find the perfect aiming circle stock photo, image, vector, illustration or 360 image. For as little as $1 a month, our members receive exclusive early-bird notice of military-themed writing opportunities, events, and markets! An apparatus as claimed in claim 13, wherein said second piece of artillery comprises a howitzer. 2 shows the combat tactics which are considered likely to be most effective. lg.s.F.H."13). An apparatus as claimed in claim 1, wherein said first and second ground stations receive the P code from the geopositioning system. [7] Haufen, sometimes in the compound Gewalthaufen, also designated a pike square formation in German. For as little as $1 a month, our members receive exclusive early-bird notice of military-themed writing opportunities, events, and markets! A second GPS ground station is located at a distance from the first station. 14. RM PKF0NG - The M2A2 Aiming Circle, Lay Circle, left, and Safety Circle, are used to angle the M777 towed 155mm howitzer used during exercise Summer Fury, at Range 2057 South, Calif., Aug. 1, 2018. A fire direction center (FDC) 37 is positioned to direct the battery and also may contain a GPS receiver. An apparatus as claimed in claim 2, wherein said means for determining the distance between the first and second GPS ground stations comprises a separate range finding device at said first GPS ground station. 12. The training worked on two aspects of howitzer operations: sighting and firing. The howitzer provides direct and indirect fire support to the forces deployed in combined arms operations. 251 Howitzer Circle Caroylyn Couch, Rodger Couch and eight other residents. 4-2. Specifically, now ballistics computers that you input the GPS coordinates of your target, wind speed, humidity, and temperature and it spits out the elevation(up and down), windage(left and right), and load(amount of powder). A mountain howitzer is a relatively light howitzer designed for use in mountainous terrain. Various technological solutions have been proposed for making the artillery more nimble and maneuverable. The speed of positioning the artillery is increased by positioning the GPS receiver with the gunner, preferably by incorporating a GPS antenna and RPU unit directly into the trunnion of a howitzer. A redundancy of GPS stations is also desirable in the event that a GPS receiver processor or communication link becomes disabled.

The aiming stakes were viewed through a panoramic sight and, with the aid of an aiming instrument such as a mil scale, the angle to the target was measured off of the line determined by the aiming stakes. Thus, the present invention provides its own back up system in the event that the GPS positioning technique fails for any reason. means for protecting said gunner from chemical, biological and radioactive (CBR) contaminates at said second piece of artillery. U.S. Marines from 2nd Squad, 1st Platoon, Battery B, 1st Battalion, 11th Marine Regiment (1/11) adjust the M777 Howitzer aboard Fire Base Fiddlers Green, Afghanistan, August 1, 2010. A battery of six howitzers 31-36, representing a typical deployment for the United States Army, are dispersed on a battlefield in groups of two, 41-43, respectively. The Aiming Circle is a patron-funded community of practice, serving writers of military-themed essays, analysis, literary and journalistic non-fiction, genre and literary fiction, poetry, and more! The present invention relates to directing artillery fire. The current solutions for finding north and surveying individual howitzer batteries include steps that are essentially unchanged from methods introduced in the First World War. An apparatus as claimed in claim 13, wherein said second piece of artillery comprises an air defense artillery system such as a missile battery or a Remotely Piloted Vehicle battery. The present invention does not require a soldier to set out aiming stakes or otherwise dismount since the entire aiming process can be performed from within the protected crew compartment. Most western artilleries have experimented with dispersal tactics to protect against counterbattery fire. A good example of a weapon of this class is provided by the 9.45-inch (240mm) weapon that the British Army purchased from the Skoda works in 1899. Thus, the present invention is not only fully compatible with present artillery equipment but also enables an artillery battery to continue firing by using other positioning systems if the GPS NAVSTAR system is destroyed or degraded. Romanych, Marc; Rupp, Martin (2013). [14] Originally intended for use in siege warfare, they were particularly useful for delivering cast iron shells filled with gunpowder or incendiary materials into the interior of fortifications. The entire artillery battery was aligned by setting an aiming circle over a known point which had been surveyed by the survey parties. Rather, as the field guns of the day were usually restricted to inert projectiles (which relied entirely on momentum for their destructive effects), the field howitzers of the 18th century were chiefly valued for their ability to fire explosive shells. A firts GPS ground station is incorporated into a howitzer. 1 shows the components of an artillery positioning system of the present invention in use on a howitzer; and. An apparatus as claimed in claim 8, wherein: said GPS ground station and RPU are incorporated into said trunnion so as to be directly accessed by a crewman of said howitzer. Enterprise.
