GNSS-receiver satellite geodetic multi-frequency SIGMA. Modifications: Sigma-3 Sigma-3N Sigma-3S SigmaDM SigmaDM SigmaDM-IMU Sig

The Sigma receiver family is based on the Triumph technology embodied in the Triumph VLSI. Powerful and reliable receivers Sigma can be used in high-precision navigation systems, including systems with high dynamics of objects, in traffic control systems. Sigma receivers are indispensable in most applications requiring high positioning accuracy, such as continuously operating base stations (CORS). For the first time in GNSS history, we offer real-time kinematics (RTK) with decision rates up to 100 Hz. The SigmaS receiver includes a TRE-G2T or TRE-G3T or TRE-G3TAJ board, the SIGMAD receiver includes a Duo-G2 or Duo-G2D board, and the SigmaQ receiver includes a Quattro-G3D board. With the ability to track and process L1/L2/L2C, E1 GPS, Galileo and GLONASS signals, as well as SBAS and L5, E5, SIGMA receivers provide reliable results. The receivers have a full-fledged CAN-interface with the necessary hardware and software support for its operation, as well as RS-232/422 ports.
