Flight test results of the Rockwell MIGITS

Abstract

A new standard of lightweight, low cost, integrated GPS/INS products has been created with the introduction of Rockwell's family of MIGITS (Miniature integrated GPS/INS Tactical System) products. This family takes full advantage of the precision pseudorange and pseudorange rate information available only from an embedded GPS receiver. This information is integrated with inertial data in a single Kalman filter in a synergistic manner which results in superior operation in high dynamic, antenna shading, and jamming environments. The Rockwell MIGITS has successfully demonstrated ability to tightly couple a tactical grade IMU with GPS to provide precise navigation operation in a dynamic environment. The integrated systems described in this paper build upon the lessons learned and the continued evolution of GPS. Continual refinements in research and development programs at Rockwell have led to this family of small integrated systems, resulting in what is believed to be the world's smallest, integrated GPS/INS systems available today, the MIGITS. The MIGITS products are intended to satisfy the navigation requirements of a variety of applications including missiles, both fixed and rotary wing aircraft, UAV's, munitions, targets and drones. This paper provides an introduction to the various MIGITS systems, followed by a description of the system testing performed thus far. >
