ACEINNA announced its new INS1000 high-performance, dual-band RTK INS (real-time kinematic inertial navigation system) with built-in inertial sensors for automotive, construction, and agriculture applications. The INS1000 embeds ACEINNA’s 9-degree-of-freedom inertial sensor technology to achieve automotive dead reckoning performance in GNSS-challenged environments such as urban canyons, heavily tree-lined roads, tunnels, underpasses, and bridges. The dual-frequency RTK and tight coupling between GNSS and inertial sensors provide centimeter-level accuracy, enhanced reliability, and superior performance during GNSS outages.
“Without access to satellite delivered guidance and localization information, autonomous vehicles can quickly get off track,” said Mike Horton, CTO of ACEINNA. “The INS1000 delivers the essential detailed position and heading accuracy at a price point that is suitable for startups as well as fleet-wide vehicle deployment. As the leading supplier to the precision agriculture autosteer market, ACEINNA is focused on driving the cost and complexity out of GNSS/INS solutions to enable wide-spread adoption in automotive ADAS applications.”
INS1000 is an integrated navigation system consisting of an inertial measurement unit (IMU) and other sensors. It 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) that can be attached to a wheel of the vehicle/robot to measure the rotation rate of the wheel. Integration of a DMI would give an improved solution in challenging environments.
With horizontal position accuracy of 2 cm (RTK), vertical position accuracy of 3 cm (RTK), and velocity accuracies of 0.01 m/s and 0.02 m/s (horizontal and vertical, respectively), the INS1000 is designed to provide the precision navigation capabilities required for the automotive autonomous, automotive track testing, precision agriculture, and construction markets.
The INS1000 is reportedly 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.
The embedded software allows extensive configuration and diagnostic capabilities. For optimal flexibility, the tools enable configuration of the output position, initialization of heading, IMU transformation matrix, GNSS antenna lever-arms, and NTRIP client. The control software can log and decode output data from the system or use the web application to plot results on a map.
