Integrated GPS/INS Navigation System Based on a Gyroscope-Free IMU

This paper analyses the performance of a low cost INS, based on a gyro-free IMU that only uses multiples accelerometers and is aided by a GPS receiver. The IMU is composed by a specific array of accelerometers such that linear and angular accelerations can be computed. The GPS/INS loosely integration approach is implemented by a Kalman filter. The performance of the integrated system is assessed by using computer simulation.
