On the other hand, for given positioning performance indices, simulations are carried out to present the inversion of parameters. On one hand, the influence of each factor on the positioning performance is quantitatively analyzed under the circumstances of various constellation deployment schemes and user types. Using the weighted dilution of precision as the evaluation criterion, we study the theoretical relationship between the internal parameters and the positioning precision during the evolution of the system. Both the increase in the number of the MEO satellites in the constellation and the decrease in the user equivalent ranging error of the GEO satellites will improve the overall positioning performance of the system.

Satellite Navigation System Stepwise Deployment Weighted Dilution of Precision Positioning Precision System EvolvementĪlong with the planning and implementation of the COMPASS satellite navigation system, first as a regional then a global system, there is a need to probe into the positioning performance of the mixed constellation in the stepwise deployment scheme. The Country Movers App builds on terrestrial geographic knowledge and combines planetary cartography, mission planning and planetary exploration, in an easy-to-use online tool for which a wide range of educational activities and research applications can be developed from middle school to professional levels.
