Design, Implementation and Performance Analysis of an INS/GPS Integrated System Using FPGA

A. G-Quinchia, C. Ferrer

Abstract:	GPS provides accuracy in the positioning information, but in applications where a high accuracy is necessary, the GPS is not enough because it is affected by several errors and also has slow update rate. On the other hand, INS provides position, velocity and attitude with a higher update rate. Despite this, INS presents an error which is increased in a short period of time due to the inertial sensors. To take advantage of both instruments, we go for the GPS/INS integration which provides a higher accuracy than their stand-alone operation. This paper describes the development of Loosely Coupled GPS/INS integration based on FPGA. This novel modular platform based on FPGA presents an architecture that has a lowcost, small size, low power consumption, it is flexible and with a low risk system design methodology that can be useful in several applications where the fusion GPS and INS is carried out.
