Multi-constellation 9 DoF inertial sensor is centimeter accurate

January 29, 2019 // By Julien Happich
Aceinna’s INS1000 dual band RTK INS (Real-Time Kinematic Inertial Navigation System) comes with built-in inertial sensors for construction, agriculture and automotive applications.

The INS1000 embeds the company’s 9 degree-of-freedom inertial sensor technology to achieve automotive dead reckoning performance in GNSS challenged environments like urban canyons, heavily tree lined roads, tunnels, underpasses, bridges, etc. The dual frequency RTK and tight coupling between GNSS and inertial sensors provide cm-level accuracy, enhanced reliability, and superior performance during GNSS outages.

The integrated navigation system provides the position, velocity and attitude information of the vehicle. A dual-frequency (L1/L2), dual-antenna GNSS receiver is used as the primary aiding sensor. Also supported is a distance measurement indicator (DMI) which can be attached to a wheel of the vehicle/robot to measure the rotation rate of the wheel. With horizontal position accuracy of 2cm (RTK), vertical position accuracy of 3cm (RTK), and velocity accuracies of 0.01m/s and 0.02m/s (horizontal and vertical, respectively), the INS1000 provides the precision navigation capabilities required for the automotive autonomous, automotive track testing, precision agriculture, and construction markets.

The INS1000 is compatible with all major global satellite systems (GPS, GLONASS, Beidou, Galileo, SBAS); it supports USB, Ethernet, CAN and RS-232 interfaces; and it supports dual GNSS antennae for accurate heading in static and dynamic scenarios, and difficult magnetic environments.
