On Ground Test of an IMU/GNSS Receiver for Atmospheric Re-Entry Vehicle Applications

This article introduced the on ground test of a novel IMU/GNSS integrated navigation system foratmospheric re-entry applications. Dynamic and kinetic model of re-entry vehicle are introduced with proper coordinates, and dynamic and kinematic equations for angular motion are also provided by using Euler’s Law and quaternions. The sensor bias, scale factor and misalignment in inertial system are provided in detail, and the principle of SINS mechanization is given, which can easily be inserted to GNC closed loop. On ground and underground vehicle test results are provided that demonstrated the promising performance of this IMU/GNSS receiver for atmospheric re-entry applications.
