The ArNav M2 is the high performance series of the ArNav product family with 4 different products. The products offer different functions with different levels of filtering. Arnav M2 series consists of GNSS/INS (ArNav M2G), real-time kinematic GNSS/INS (ArNav M2GR), dual band RTK GNSS/INS (ArNav M2D) and double antenna GNSS/INS (M2HD).
ArNav M2G is an advanced GNSS aided inertial navigation system (INS) that provides accurate position, velocity, acceleration and attitude data under the most demanding conditions. It combines a high performance 3D inertial sensor assembly (gyroscopes and accelerometers), 3D magnetometer, static pressure sensor, temperature sensor, 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) with an advanced sensor fusion algorithm. ArNav M2G provides accurate 3D position, velocity and attitude. ArNav M2G supports different user requirements with its unique and well-designed architecture.
ArNav M2GR is a state of art RTK GNSS aided inertial navigation system (INS) that combines a high performance 3D inertial sensor assembly (gyroscopes and accelerometers), 3D magnetometer, static pressure sensor, temperature sensor, with an RTK capable GNSS receiver that can receive and track multiple GNSS constellations (GPS L1C/A, GLONASS L1OF, Galileo E1-B/C and BeiDou B1l). RTK capable ArNav M2GR accepts RTCM data and process the raw data to provide very accurate position/velocity and attitude solutions.
ArNav M2HD is a double antenna GNSS aided inertial navigation system which can also aided with RTK and gives centimeter position accuracy. Double antenna GNSS is capable of tracking multiple band, multiple constellation (L2OF, L2C, E1B/C, B2I, E5b, L1C/A, L1OF, B1I). ArNav M2HDR provides very accurate pitch/yaw data under any circumstances using sophisticated algorithms exploiting the advantages of double antenna configuration. ArNav M2HDR accepts multi-band, multi-constellation RTCM data including GPS, GLONASS, GALILEO and BeiDou.
