Single-antenna Gps Attitude Determination System

The attitude is the important parameter of navigation of the plane. Inertial navigation system was used to get attitude information at the past. As the development of GPS technology, the application of synthesizing aircraft attitude information based on GPS has become the important part of the use of GPS. It can take the full or part place of the inertial navigation system. Several GPS attitude determination methods have been proposed and successfully tested in recent years. These methods rely on the use of multiple antennas.This paper presents a method for synthesizing aircraft attitude information from single-antenna GPS velocity measurements. The attitude information consists of flight path angle and roll angle about the aircraft velocity vector axis. It also called as pseudo-attitude. It is a practicably method to get aircraft's attitude information with low cost for its simple hardware and easy installation.
