The receiver is intended for:

– Reception of signals from GLONASS / GPS satellite navigation systems (and SBAS functional additions);
– continuous determination of the current navigation parameters of the navigation object in which it is used;
– issuance of the received information to the consumer’s equipment.

The GNSS receiver provides the following basic tasks:

reception and processing of SNA signals:
– GPS / SBAS, L1 (C / A code);
– GLONASS L1 (CT code);
automatic continuous determination of three coordinates (latitude, longitude, altitude), time, course and speed;
issuance of current coordinates to external devices in the coordinate system WGS-84, SO-90, SC-42, SC-95;
issuance of navigation data with frequency 1, 2, 5, 10 Hz;
estimation of accuracy of determination of coordinates of a consumer’s place;
receiving and updating the SNA GLONASS / GPS / SBAS almanacs;
automatic selection of the system from visible NSA SNS GLONASS and GPS taking into account their technical condition;
exchange of information with external systems and devices on the RS-422 digital interface in accordance with IEC 1162 (NMEA – 0183) and BINR. The protocol is selected and configured using commands from the consumer’s equipment;
receiving and accounting for corrective information in accordance with the recommendations of RTCM SC-104 V2.2;
RAIM control of satellite signals;
issuing a 1PPS second timestamp to the consumer’s equipment;
operating in Time-to-Time Fix (TTTF) energy-saving mode;
data delivery in TTTF mode * with 10, 15, 20, 30, 60, 90, 120 sec.
* TTTF mode switches the receiver, after solving the navigation task, to the low power mode, and cycles through the user-defined period of time to the mode switching to the navigation task solution.
