MIT Kit For Multifunctional Target Instrumentation

Chun Yang

Abstract:	In a highly dynamic environment, neither a low cost IMU nor a GPS receiver alone can meet accuracy requirements. This is because of fast error growth under large excitations for the former while of signal interruption for the latter. However, an integrated GPS/IMU system with proper configuration has the potential to provide all the information necessary within the required accuracy. Different from other GPS applications where real-time on- board processing is required, target instrumentation for weapon testing is for ground control and evaluation, thus allowing for near real-time as well as off-line processing. Such a unique application gives rise to a multifunctional GPS/IMUmM kit concept (called MIT kit), which is presented in this paper with emphasis on various processing modes and their integration. This includes self- alignment of IMU on the ground; flyout calibration of IMU with GPS; transfer alignment; and relative navigation in separation and scoring. Simulation results of the effects of various error sources and system parameters on the integrated solution are also discussed.
