GEODETIC NETWORK OF MOSCOW
HISTORY OF THE MOSCOW GEODETIC REFERENCE NETWORK
The regular geodetic basis of the city of Moscow was firstly created in 1833 as a triangulation network. Its points are located on the territory of Moscow and in the surrounding areas of the Moscow region. The reference geodetic network of Moscow (russian abbreviation - OGS) has been actively developing all the time, but significant improvement works began in 2001. The need for improvement came from the insufficient density of OGS points and the appearance of modern high-precision geodetic technologies. First of all, satellite methods for determining coordinates influenced the work. Nowadays a reference geodetic network is operated throughout the capital, including TiNAO.
NAVIGATION AND GEODETIC SUPPORT SYSTEM OF MOSCOW (MOSCOW NGSS OR «SNGO OF MOSCOW»)
The Navigation and Geodetic support System of Moscow (Moscow NGSS or in russian abbreviation “SNGO of Moscow”) is intended to create the satellite navigation space in the capital and adjacent territories of the Moscow region. Within the specified space, it is possible to determine the coordinates of your own location as it is determined by GNSS GLONASS/GPS signals. Moreover, it works in both post-processing and real-time mode. The number of users is unlimited.
High precision is provided by a high-quality geodetic basis of:
- Moscow NGSS base stations;
- points of the frame geodetic network in the coverage area, which were used to output common parameters (keys) of the transition, as well as to adjust the height model of the quasigeoid.
Today the System consists of 21 base stations, each of them includes:
- GNSS receiver for Leica Geosystems base stations;
- antenna with Choke Ring anti-reflection screen with protective cover.
The latest "SmartTrack+" technology is implemented in the base station receivers. Certainly this technology allows to monitor satellite signals and get positioning results.
The stations provide round-the-clock reception of GLONASS and GPS satellite signals. In the same way transmitting information in real time to the data processing center of Mosgorgeotrest is proceeded.
Afterwards the high-precision positioning center monitors the quality of measurement information and generates data for both post-processing and real-time operation.
The coverage area of the Moscow NGSS is the territory of the city of Moscow and adjacent districts of the Moscow region.
