Abstract

The accuracy of positioning with GPS depends on wavelength. Therefore, positioning is more precise by using the carrier whose wavelength is shorter than chip length of code. So, we propose to improve the accuracy of Inverse-GPS by applying the positioning with carrier phase to Inverse-GPS. In positioning with carrier phase, the most important problem is integer bias. By using 5 receivers or 2 frequencies, this problem can be solved. Next, we took up the multipath as an error factor of inverse-GPS. It is thought that inverse-GPS is greatly influenced by multipath compared with GPS since inverse-GPS has a transmitter and a receiver on the ground. Then, we propose using adaptive filter to remove multipath.
