SIGMA receiver is based on our TRIUMPH2/TRIUMPH Technology implemented in our TRIUMPH Chip. For the first time in the GNSS history we offer up to 100 Hz RTK.

864 channels of dual frequency GPS, Galileo, GLONASS, BeiDou, QZSS and IRNSS in a small attractive, sturdy, and watertight box, which contains either TRE-3N, or TRE-QUATTRO board.

216 channels chip is being utilized in SIGMA, which contains either Duo-G2, Duo-G2D, Duo-G3D, TRE-G2T, or Quattro-G3D board.

The on-board power supply on SIGMA receiver accepts any voltage from +10 to +30 volts and delivers clean filtered voltage where needed. This eliminates the risk of power contamination (ripples) that can be created when clean power is generated elsewhere and delivered to the board via cables. SIGMA receiver also includes TriPad (two LEDs, ON/OFF and function button), Cellular module, UHF modem, and batteries. In addition, the receiver comes with large amount of flash for data storage. The CAN interface in SIGMA receiver is provided complete with all associated hardware and firmware, not just the CAN bus. The same is true with all the serial RS232/RS422 ports in our receiver. Simply stated, additional functions are not needed to incorporate any of our SIGMA Receiver in most applications.

In addition to timing strobe and event marker, the SIGMA receiver includes the option of complete IRIG timing system.
