Abstract

The invention discloses a system for tracking, monitoring and correcting trajectory deviation of artificial rain-increasing and hail-preventing rocket projectile sowing operation. The system comprisesa projectile-borne antenna module, a satellite positioning module, a data transmission module and a rain-increasing projectile trajectory display module. The projectile-borne antenna module is used for receiving Beidou / GPS information, launching positioning information and data parameters; the satellite positioning module is used for positioning the rocket projectile in the flight process and measuring the aerial position and the flight direction of the rocket projectile; the data transmission module comprises a data transmission transmitting module and a data transmission receiving module; and the rain-increasing projectile trajectory display module receives the actual trajectory data of the rocket projectile output by the data transmission receiving module, so that the angle and the direction of a launching tower are able to be corrected conveniently. The system can track the whole course track from flight into the clouds of the rocket projectile to the end of sowing, has great significance on operation guidance, operation analysis and operation effect evaluation of artificial rain-increasing and hail-preventing operation, and the scientific level of the integral artificial rain-increasing and hail-preventing operation is favorably improved.

Description

technical field [0001] The invention relates to the technical field of positioning and transmission of rain-increasing projectiles, in particular to an artificial rain-increasing and anti-hail rocket sowing operation tracking monitoring and ballistic correction system. Background technique [0002] Conventional positioning and transmission technology is not a problem at present, but the rain-enhancing and hail-proof rocket has the characteristics of fast flight speed (up to 800km / h) and short spreading time (40 seconds), which requires The rapid positioning of the rocket and the rapid real-time transmission of data are realized on the basis of [0003] In terms of communication technology, the current routine data transmission methods mainly include Beidou satellite communication, 4G network communication and radio communication. Among them, the Beidou satellite navigation system in satellite communication has the function of data downloading, but the civilian Beidou satell...

AI Technical Summary

Problems solved by technology

Among them, the Beidou satellite navigation system in satellite communication has the function of data downloading, but the civilian Beidou satellite navigation system generally transmits a set of data at intervals of 30-60 seconds. If it is applied to a rain-enhancing and hail-proof rocket, it has the disadvantage of too long a transmission interval ; 4G network transmission can take the method of storing GPS location information on the rain-increasing and hail-proof rocket, and using the 4G signal of the ground base station to transmit the stored location information back to the ground operators after the rocket lands. According to the requirements of the world, the rocket wreckage should be landed in an uninhabited area. The strength of the 4G signal in this area is unknown. At the same time, this transmission method cannot transmit the location information to the ground operators in real time, and there is an obvious lag.

[0004] In terms of positioning technology, the current civilian positioning technology mainly uses Beidou and GPS positioning. Considering the product cost, only civilian-level Beidou and GPS positioning technology can be used, and it does not have high-dynamic adaptive high-sensitivity satellite signal tracking technology and positioning acquisition time. long disadvantage

During the launching process of the rain-enhancing and hail-proof rocket, its acceleration is high, and the ordinary civilian-level satellite positioning module takes a long time to capture and locate (about 20S).
