Since May of this year begins mass production of a new type of equipment users GLONASS — receiver "Geos-3". This was announced today at the VI International Satellite Navigation Forum zamgeneralnogo director, designer, "Russian Space Systems" / RCS / Grigory Stupak.
According to him, the philosophy of the development of the GLONASS system is defined feedback and needs of consumers. To improve the performance of the navigation system, the enterprise on its own initiative, a new receiver — "Geos-3". "It is competitive with current domestic and international advanced models," — said Stupak. At present, the issue is solved ensure complete customer support GLONASS navigation signal. "We aim to improve the positioning accuracy of up to 6 cm, to provide a steady signal in rugged terrain and urban development, as well as to fulfill the requirements for signal integrity," — said the deputy director. To do this, he said, needs a surplus of space vehicles at their optimal placement in orbit, as well as the development of additional systems.
Currently, the GLONASS constellation has 31 spacecraft. Of these, 24 are used for their intended purpose, 2 In maintenance, 4 are in the orbital reserve, 1 — on the stage of flight tests. For the continuity of the navigation signal throughout Russia needs at least 18 operational satellites, 24 — on a global scale.
GEOS-3M, created "GeoStar navigation" is a receiver for civilian use. High receiver sensitivity and speed of positioning, combined with the small size and low power consumption can successfully apply the GEOS-3 in the equipment of various telematics systems using Glonass capabilities.
The navigation Glonass / GPS receiver GEOS-3M uses the signals from the satellites of the two navigation systems, allowing it to accurately determine the location of the facility where this is not possible in the case of a navigation system in isolation. GEOS-3M is able to receive dannyemestopolozheniya using only signals or only GLONASS GPS, as well as to work in a combined constellation GLONASS / GPS.
The structure of the hardware GEOS-3M is a 32-channel correlator with a fast search engine GLONASS / GPS, ensuring achievement of low levels for the first time determining the origin and high receiver sensitivity. Due to the hardware implementation of search algorithms, GEOS-3 provides navigation data for 28 seconds in the "cold start" and 2 seconds — the "hot" when 80mVt average power consumption in active mode and 15 mW in power-saving mode.
