Aceinna launches INS1000 for guiding autonomous vehicles
Centimeter-accurate, multi-constellation, multi-band, dual-antenna, RTK and affordable GNSS/INS solution
Aceinna is offering the INS1000 high-performance dual-band real-time kinematic inertial navigation system (RTK INS) with built-in inertial sensors for construction, agriculture and automotive applications.
Aceinna has also launched an OpenIMU package for autonomous vehicle guidance and navigation.
The INS1000 embeds Aceinna’s nine-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 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, the company said.
“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 widespread 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) which 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: urban canyons, tunnels, warehouses and indoor facilities and campuses.
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 antennas for accurate heading in static and dynamic scenarios, and difficult magnetic environments.
The easy-to-use 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.
Open IMU Package
Aceinna also offers an OpenIMU package. Its three key parts are:
a family of IMUs (three high-accuracy accelerometers, three high-accuracy gyros, and a powerful ARM Coretex);
an OpenSource tool chain and reference code for programming the IMU, with everything from basic download and debug to reference implementations of loosely coupled GPS/INS
a full developer site and tools with charting, graphing and algorithm simulation.
