Features of an estimating algorithm formation of state vector of high elliptical satellite with use of GLONASS and GPS signals meant for on-board implementation |
S.V. Averin
Some features of an estimating algorithm formation of state vector of high elliptical satellite are discussed. This algorithm uses signals of the GLONASS and GPS systems and is purposed for on-board implementation. The main task of algorithm such as this is real-time operation to lead to enhancing autonomy of the satellite in a high degree. Updating state vector error covariances is suggested in order to achieve higher accuracy with some interval which is distinct from an interval of receipt of measurements. Such an approach reduces the negative impact of correlated measurements on accuracy of state vector estimates. |
