SIGMA

Product catalog summary

Overview
The SIGMA is a versatile GNSS receiver designed for applications requiring Real-Time Kinematic (RTK) positioning. It supports GNSS Heading and roll/pitch measurements from a MEMS IMU. The device includes an internal battery, dual power inputs, and standard I/O interfaces, making it adaptable for various GNSS configurations. It features integrated cellular and radio communications, allowing it to function as a Reference Station with NTRIP Caster and Server capabilities for transmitting RTCM corrections via TCP or NTRIP.
