A Prototype Design of Next Generation Low-Cost Software-Defined MEMS Gyroscopes for Navigation Applications

Kaixiang Tong and Yang Gao

Abstract:	This paper describes a new concept of GNSS/INS integration that is conducted in the signal domain of GNSS and INS systems. Previous efforts have been made to the GNSS/INS integration in the signal domain of GNSS receivers including ultra-tight integration algorithms and the introduction of software-defined receivers (SDR) to allow flexibility in GNSS receiver design and performance improvement. In this paper, we focus on the introduction of a software-defined IMU (SDI) to support GNSS/INS integration in the signal domain of the INS system. To demonstrate the new concept and considering the fact that gyroscope has a greater impact on the performance of IMU, a prototype system of a software-defined MEMS Gyroscopes (SDG) has been designed and implemented which is also tested in a road test. The concept of SDI opens new ways to improve the low-cost IMU design and performance particularly in challenging environments.
