This paper presents a preliminary result of the effectiveness study on vector-tracking-loop for different signal fading effects for different satellite signals in analytical way. In order for this, we use a simple model with a constant pseudorange measurement covariance for all satellites available in channels. After then, we expand the result to the general case of signal fading where only several...
The Chinese Area Positioning System (CAPS) is a new type of satellite navigation systems. The geostationary satellites for normal communication with 2 or 3 sets of inclined geostationary orbit (GEO) satellites are employed to construct a satellite navigation system. The navigation signals are constructed and disseminated on the ground, and the satellites only transfer the signals to the ground by...
For safety of life applications of satellite navigation systems, in e.g. aviation, reliability in the sense of accuracy, availability, continuity and integrity is essential. In order to test the performance with regard to these characteristics a test methodology is required. This methodology should meet the requirement to be able to perform the analysis based on a limited amount of data collected...
