The results showed that the positioning accuracy could be improved by 20–30% with the modeled attitude, especially when more GPS IIA satellites were in eclipse.
The results show that the influences of non-nominal attitudes are related to the magnitude of the PCO values, maximum yaw angle differences, the duration of ...
Deleting the eclipsing satellites may sometimes induce a longer convergence time and a worse solution due to the poor satellite geometry, especially for GLONASS ...
Because different generations of satellites adopt different attitude control models, the influences on the positioning performances deserve further study.
For instance, GPS ⅡR satellites can experience noon and midnight turn maneuvers, GPS ⅡF satellites suffer from noon maneuver and shadow crossing, and GPS Ⅱ/ⅡA ...
