Archimedes Innovation INS620-232

The Archimedes Innovation INS620-232 is a GNSS/INS Integrated Navigation Smart Terminal combining satellite reception with MEMS inertial sensors. Its built-in fusion algorithm delivers real-time position and three-axis attitude information, while inertial assistance supports vehicle positioning, speed measurement and heading when satellite reception degrades or is lost.

Product overview

The Archimedes Innovation INS620-232 combines a three-axis gyroscope, a three-axis accelerometer and a GNSS module with a built-in fusion algorithm for positioning and attitude determination. It delivers real-time compensated three-axis attitude and position information, together with vehicle speed and heading information for environments including indoors, tunnels and underground parking garages. When satellite reception degrades or is lost, inertial navigation maintains positioning and measurement without odometer support. In this mode, navigation accuracy is meter-level, specified as 3% CEP @ 120s.

Its receiver provides 120 tracking channels, a dedicated search engine and L1 reception for GPS, BeiDou, Galileo, QZSS and GLONASS, alongside SBAS support. A built-in high-gain LNA, multipath detection and interference suppression support signal reception. The terminal communicates through UART232 at a default 115200 bps and supports NMEA-0183. Measuring 40x32x16mm and weighing 121g, it operates at 9V~36V with power consumption below 200mW and an operating temperature range of -40℃~85℃. The cable specification is Molex 4-Pin, L=3000±50mm.
