Abstract
The performance of real-time differential GPS navigation are affected by the satellite constellation available, the characteristics of user equipment, the data processing method used, the specifications of the data link used to broadcast the data from the reference station to the mobile platform, and the distance between the reference station and the platform. Each of the above parameters are discussed and related errors are quantified. The effect of user equipment characteristics such as code and carrier phase noise, multipath rejection capability, and number of tracking channels, is discussed. The use of latency is quantified as a function of the data processing method and receiver type used. Various aircraft positioning case studies are used to illustrate the capability of the system under various conditions. Attitude determination using a multi-antenna configuration is described, together with limitations due to fuselage stability and wing flexing. The results of various flight test are described to illustrate the performance levels achievable.
