摘要

The data is presented on development and testing an onboard synchronizing positioning/timing device (OSPTD)for high accuracy navigation/timing support as regard flights on space vehicle (SV). By now, the equipment junctions successfully, and the data obtained are used in the course of the routine operation in the SV's control loop. The integration within a single OSPTD of such devices as 1. Onboard synchronizing device and time keeper and 2. Receiver of signals from GLONASS/GPS, enabled one to solver task of the SV time synchronization and tasks of determining SV orbital position without using terrestrial loop aids. This resulted in the improvement in accuracy parameters as regards the SV's positioning/timing support and in the significant reduction of expenses for operations of control and ballistics support for SV trajectory/ The time keeping error was no more than 0.5 μs and the error of SV's mass center motion parameters (MCMP) was about 10 m according to the measurement results. The integration of satellite navigation equipment and celestial coordinators into a signal complex of the positioning/timing support (PTS) is caused by the necessity to take such factors into account as the attitude of SV for Earth's remote sensing (ERS) and its dynamics for supporting high-accuracy navigation determinations. This allows to solve a wide complex of problems as regards control over SV flights and coordinates' referencing for surveying and measurement performed with these SVs. The specialists from RIRT and SRIRAS began to develop measurement equipment for the precise PTS (EPTS) solving all the problems related to the determination of SV's navigation/attitude parameters. At the first stage, the EPTS will be a system integrating OSPTD and ST at the information level; at the second stage both measurement devices will be united into a single integrated device. In the end, the PTS integrated equipment will provide an efficient and complex solution of problems related to the control over SVs for ERS.
