“…There are standard formats such as STANAG 4119 [3] but a simple format that is easy to understand is also acceptable. In addition, the trajectory model can be used by a firing solution algorithm such as [4,26] to compute firing angles for any set of conditions.…”

This paper describes a quick method to predict the impact point of an artillery rocket when it is equipped with a non-standard fuze and the firing tables and a fire control program supplied by the rocket manufacturer become no longer accurate. The method has been applied to a 122 mm artillery rocket that was originally designed to be used with MRV-U fuze but it was replaced by M423 fuze. Live fire tests of six rockets were conducted at a half range and a full range. The impact points were measured by a radar. From the test results, the average relative error of predicted range by the proposed method was -1.4% at half range and -3.3% at full range.

“…The simplest model given by point mass model defines trajectory in a plane which generally is used to estimate range and maximum altitude. The third direction giving drift is obtained using modified point mass model 6,7,11 . The complexity increases by considering additional forces or moments like those due to rotation of Earth, spinning of projectile and wind.…”

Projectile path is dictated by estimated line of fire. Line of fire can be estimated by referring RT as well as trajectory model on computer. RT is prepared under ISA/ICAO meteorological standard conditions without wind effect. Meteorological conditions like density, humidity, pressure, wind, temperature affect the path of the trajectory. Meteorological data plays very important role in trajectory prediction. Trajectory is predicted using RT for a particular weapon where ICAO standard met data is used. Ind Std met data is different from ICAO data. Use of Ind Std data improves the accuracy of trajectory prediction for Indian field deployment. In this paper, comparative study of effect on projectile path under ICAO, Ind Std and actual Indian prevailing met have been carried out and analyzed. From this analysis, a new model has been established that if actual prevailing met is not available then trajectory prediction can be carried out using Ind Std met data with wind data as per date and time. It predicts trajectory very close to actual. Effect of wind has been studied and found that wind effect is very dominant on projectile path. Study of effect of density also has been carried out in this paper. It is observed that Ind Std density values are much close to actual as compared to ICAO. Therefore, if insufficient met is recorded then Ind std density can be used to fill density values for that region.

“…Traditionally, firing tables are used to calculate the standard projectile firing data needed to hit a desired target and also compute the firing data corrections in case of non-standard flight conditions [3]. These nonstandard flight conditions are resulted from variances in various parameters such as meteorological data, projectile mass properties, propellant temperature, and altitude difference between the launch point and the target [4]. To improve the weapon's hit accuracy, these nonstandard flight conditions have to be predicted accurately as well as possible especially the meteorological data [5], [6].…”

Abstract. The artillery has been praised as "the god of war". Modern warfare requires the self-propelled artillery to have the ability to correct shots accurately. Most of the current fire control lacks of research in correct firing based on the mean point of impact. In order to improve the accuracy of the self-propelled artillery firing by use the mean point of impact, this paper established the launch and flight dynamics models of the self-propelled artillery by Multi-body System Transfer Matrix Method (MSTMM) and calculated the mean point of impact of the self-propelled artillery. The simulation results agree well with the experiment. The method of shooting correction based on the mean point of impact is established. The results provide a theoretical basis and technical means for improving the shooting accuracy of the self-propelled artillery.
