Determination of Flight Vehicle Position and Orientation Using the Global Positioning System
In this paper we document the development of a numerical method for the determination of the position and angular orientation of a body using the Global Positioning System (GPS). By using data collected from multiple antennas on board a single flight vehicle, and by employing differential corrections supplied by a fixed ground receiver, this numerical method can produce Earth Centered Earth Fixed (ECEF) coordinates for a specified point on a vehicle, as well as the Euler angles (pitch, roll, yaw) expressing the angular orientation of the vehicle at that point. This analysis has applications for any mobile platform where position and orientation information is desired. The particular application we tested is in regards to aerial photogrametry.
