FIELD: astronautics.
SUBSTANCE: invention relates to means of determining orbits of spacecrafts. System of trajectory measurements includes one or more spacecraft on a sun-synchronous orbit, means of monitoring onboard equipment of the range-Doppler system (RDS) of spacecraft associated with one or more automated workstations (AWS). AWS hardware and software provide preparation and loading of source data files in RINEX format. It includes files of navigation measurements of on-board hardware of DDS and ground stations of augmentation and monitoring system (SDKM-KFD) and/or RDS, as well as data on parameters of rotation of the Earth and ephemerides of navigation spacecraft of GLONASS system. Using the graphical user interface on the AWS, trajectory measurements and measurement sessions are processed, the boundary task is determined to determine the spacecraft orbit. Hardware errors are determined based on processing of code pseudo-ranges, phase pseudo-ranges and pseudo-speeds. At that, differential operating modes of satellite radio navigation system are organized.
EFFECT: technical result is higher accuracy of determination of spacecraft orbits.
