Functions

The receiving and measuring device provides operation on the basis of SNS GLONASS signals or GPS NAVSTAR signals, or on the basis of both systems signals simultaneously, and represents a 24-channel digital receiver able to receive 24 navigation signals of these systems simultaneously. The receiver uses sharp channel separation of GPS NAVSTAR and SNS GLONASS to secure advanced jam-protection. Frequency plan of GLONASS implemented in the unit corresponds to the 2 stage of alterations according to Control interface document ... with possibility of transfer to the 3 stage since 2005 by means of modification of the receiving and measuring device software. The receiving and measuring device includes built-in signal simulator providing off-line test and integrity control of the receiver.

The receiver provides a search and tracking of SNS GLONASS and GPS NAVSTAR signals, automatic continuous on-line scaledetermination and delivery of the following information to consumers:

  • Object location coordinates in geodesic and geocentric coordinate systems;
  • Altitudes relative to the reference ellipsoid and relative to the Earth centre;
  • Three components of the relative airspeed vector in the geodesic and geocentric coordinate systems;
  • Current time in the time scale UTC (or local time in case of correction introduction);
  • Root-mean-square value of the predicted accuracy of location coordinates.

Features:

  • Providing navigation on the basis of SNS GLONASS/GPS NAVSTAR/SBAS signals;
  • Reception of differential corrections in accordance with RTCM SC 104 v2.2 recommendations;
  • Generation of time marker 1PPS, synchronized with UTC scale and its delivery to consumer via RS-485/RS-422 interface;
  • Saving the user's setting parameters, almanac, and the last observed coordinates after power-down;
  • Communication with user's equipment via RS-232 interface.

Data communications protocols:

  • NMEA0183(1162) - reception and transmission of navigation information;
  • BINR - equipment operating modes control, delivery of navigation data;
  • RTCM SC 104 v2.2 - reception and transmission of differential corrections.
