Bestech Australia has introduced the new GPS-aided high performance MEMS inertial navigation system that builds upon the successful heritage of the LandMark INS/GPS product line.
Representing inertial performance on par with small ring laser and fibre optic gyros, the LandMark 50 INS/GPS offers substantial improvement in performance utilising its newest high performance MEMS gyros and accelerometers combined with a 72-channel 10Hz update rate GPS receiver.
All LandMark GPS-aided products now incorporate the new 10Hz update rate GPS receiver. The internal Kalman filter software provides a navigation solution up to 4 NMPH during short-term GPS outages.
The LandMark 50 INS/GPS features an RS422/RS485 serial interface with a data rate of 100Hz (4 KHz internal sampling rate).
Key performance features of the LandMark 50 INS/GPS MEMS inertial navigation systems include 4 NMPH Free Inertial (Short-Term GPS Outages); 72 Channel GNSS: GPS, GLONASS, BeiDou, QZSS & SBAS (Galileo Ready); SBAS: WAAS, EGNOS & MSAS; 10Hz Navigation Update Rate GPS; GPS Velocity Accuracy 0.05 m/s; GPS Heading Accuracy 0.3 degrees; GPS Horizontal Accuracy ±2.0m CEP w/SBAS; Ultra-Low Noise Gyros 0.0009° /sec/√Hz; Low Noise Accels 0.02mg/√Hz (2g); In-Run Gyro Bias 1°/hour 1σ; Fully Compensated Bias & Scale Factor; Over Temperature -40°C to +85°C; Low Power <1 W typical; Input Voltage +6V to 36V; Lightweight <550 grams; Small Size <360cm³; Rugged Environmentally Sealed.
