Position-Velocity Aiding of a Mitel ORION Receiver for Sounding-Rocket Tracking
The paper describes a simple and effective concept for aiding the signal acquistion of a GPS receiver in sounding rocket applications. A segmented, low-order polynomial representation of the norminal flight path is employed to provide the receiver with approximate position and velocity values of the...
