The Tracking Loop Design for High Dynamic Missile-Borne GNSS Receiver and Parameter Optimization

Taking a 155 mm missile-borne grenade as representative and analyzing its special projectile flight dynamic stress variation and its effect on the receiver signal processing, a high dynamic receiver tracking loop strategy was put forward to adapt the special environment. Combined with the loop tracking performance theory and analyzing the tracking performance changes with the noise bandwidth of different signal tracking loop, a theoretical basis was provided for the reasonable selection of noise bandwidth. Simulation results show that, the improved design scheme can not only detect the trajectory, but also improve the detection signal to noise, which enhance the tracking performance of the receiver and the anti-interference ability.
