The ArNav S series is the entry level product of the ArNav product family with 3 different products. The products offer different functions with different levels of filtering. Arnav S series consists of AHRS (ArNav S1A), GNSS/INS (ArNav S1G) and GNSS/INS with real-time kinematic capability (ArNav S1GR).
ArNav S1A is a 3 DOF Attitude Heading Reference System (AHRS) which provides driftless real-time orientation information over the full 360º of angular motion on all three axes. It includes 3D accelerometers, 3D gyroscopes and 3D magnetometers.
ArNav S1G includes all the functions of ArNav S1A, a GNSS receiver that can receive and track all four major GNSS constellations (GPS L1C/A, GLONASS L1OF, Galileo E1-B/C and BeiDou B1l) with an advanced Kalman filtering algorithm providing accurate 3D position, velocity and attitude. ArNav S1G is a state of the art GNSS/INS system.
ArNav S1GR is the most sophisticated member of the ArNav S series, configured with a GNSS receiver that can receive and track all four major GNSS constellations (GPS L1C/A, GLONASS L1OF, Galileo E1-B/C and BeiDou B1l). ArNav S1GR thus not only outputs the all navigation data as in ArNav S1G, but also supports real time kinematic (RTK) function. RTK capability of ArNav S1GR enables RTCM data processing that yields highly accurate position/velocity and attitude solutions.
