Методика прогнозування часової похибки входу транспортного засобу у зону обслуговування радіонавігаційної станції

Abstract

The article disclosed Earth's atmosphere model refine method, using the minimum measurement information. Due to heavy density values of atmospheric predictability, at weekly intervals forecasting, time may have significant error. This may result in unstable spacecraft signal reception of ground moving vehicles and breakdown sessions management. There may be non-board equipment operations situations of capture specific information due to a significant deviation of the real spacecraft undersattelite forecast point. In this regard, it is necessary to predict possible longitudinal motion errors (on temporary amendments) prior to the regular measurement cycle current navigation parameters and refinement navigation conditions. These temporary adjustments can be quickly made in targeting the upcoming session and included in the calculation command and program information. Reconciliations of these sites and clarify unknown atmosphere model parameters performed after conversation with the spacecraft.
