Low Cost GPS/INS
| Abstract: | A new standard of lightweight, low cost, integrated GPWNS pmducts has been created with the introduction of Rockwell’s family of MIGITS- (Miniature Integrated GPWNS Tactical System) products. This famify 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. As this paper will show, the C-MIGITS has successfully demonstrated the ability to tightly couple a tactical grade IMU with GPS to provide precise navigation operation in a dynamic environment. As the primary supplier of GPS user equipment to the military, Ro&well International has pfayed a pioneering rote in the development and success of GPS. The introduction of the integrated GPWNS system advances the evofution of strapdown inertial systems and stand-alone GPS receivers that began over 20 years ago. Rockwelrs Collins AViOiliCS CommunicaWts Diviskm (CAci established aSelf in the pursuit of integrated systems with leadership in the development of both stand-alone and integrated GPS systems during the techndogy’s infancy in the earfy seventies, and has continued to help advance the state of the art to where it is today. GPS receivers have continued to advance largely through a decrease in size as well as improved performance in a variety of environments such as jamming. The integrated systems described in this paper build upon the kssons fearned 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 we believe is the world’s smallest, integrated GPSIINS system available today, the C-MIGITS. The MIGITS products are intended to satisfy the navigation requirements of a variety of appliiations including missiles, both fixed and rotary wing aircraft, UAV’s, munitions, targets and drones. This paper describes the MlGlTS product line with git2zf” a series of flight tests to characterize system performance. An introduction to the various MIGITS systems is provided, followed by a description of the system testing performed thus far. Current system perfonance is described based on a series of flight tests performed with C-MIGITS, the first system of the MIGITS product line to be devekped. |
