The INS1000, says the company, is the industry’s most accurate system for guiding autonomous vehicles, drones, robots, agricultural, and construction machinery. The device embeds the company’s nine-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 unit’s dual-frequency RTK and tight coupling between GNSS and inertial sensors provide centimeter-level accuracy, enhanced reliability, and superior performance during GNSS outages, says the company.

“Without access to satellite delivered guidance and localization information, autonomous vehicles can quickly get off track,” says 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.”

An integrated navigation system comprising an inertial measurement unit (IMU) and other sensors, the INS1000 provides the position, velocity and attitude information of a 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, say the company, would give an improved solution in challenging environments like urban canyons, tunnels, warehouses, and indoor facilities and campuses.

The INS1000 features a 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) – precision navigation capabilities required for the automotive autonomous, automotive track testing, precision agriculture, and construction markets. It is compatible with all major global satellite systems; supports USB, Ethernet, CAN and RS-232 interfaces; and supports dual GNSS antennae for accurate heading in static and dynamic scenarios, and difficult magnetic environments.

Embedded software allows extensive configuration and diagnostic capabilities. 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.
