AN INTEGRATED PRECISION SYSTEM OF ERS SATELLITE AUTONOMOUS EGRO-BASED NAVIGATION: BUILDING PRINCIPLES

摘要

The report deals with building principles of an integrated precision system of autonomous navigation for Earth remote sensing spacecraft based on extended ground reference objects K (EGRO). The system is meant to back up conventional satellite navigation systems. The use of EGRO is substantiated for provision of world-wide system operability. Building principles of structural scheme of the system are developed. A method of system decomposition into intra-plane and extra-plane subsystems is developed. A method is developed for analytical assessment of accuracy of each subsystem. To increase reliability of the system, the basic theory of optimal Earth surface scanning is developed.
