Aceinna ships $150 high precision navigation solution for autonomous vehicles

02 April 2020

Aceinna has reduced the cost for developers creating mission critical guidance and navigation systems for autonomous vehicles - robots, drones, industrial, construction and agricultural machinery - with the new OPENRTK330L. The solution can replace the expensive and bulky precision real-time kinematic (RTK)/inertial navigation systems used in today’s autonomous systems and is available in quantity for about $150 each as compared to $10,000-plus systems currently utilized to generate the same result.

The company’s test vehicle recently drove from the San Francisco Bay area to the CES 2020 event in Las Source: AceinnaSource: AceinnaVegas using this new module. Path and accuracy performance data were comparable to recorded location data generated by a $10,000 industry gold standard system in the trunk of the car, demonstrating potential for engineers to develop autonomous devices and vehicles at an affordable price point.

Aceinna's OPENRTK330L includes a triple-band RTK/global navigation satellite system (GNSS) receiver coupled with redundant inertial sensor arrays to provide cm-level accuracy, enhanced reliability and superior performance during GNSS outages. The OPENRTK330L integrates a very precise 1.5 degree/hour inertial measurement unit (IMU) to offer ten to thirty seconds of high accuracy localization during full GNSS denial. The OPENRTK330L's embedded Ethernet interface allows easy and direct connection to GNSS correction networks around the world, and the CAN bus interface allows simple integration into existing vehicle architectures.

The multi-band GNSS receiver can monitor all global constellations (GPS, GLONASS, BeiDou, Galileo, QZSS, NAVIC, SBAS) and simultaneously track up to 80 channels. The module has RF and baseband support for the L1, L2, and L5 GPS bands and their international constellation signal equivalents. By integrating a triple-redundant IMU array, the OPENRTK330L is able to recognize and utilize only valid sensor data, ensuring high-accuracy protection limits and certifiability under ISO26262 standards. Aceinna's unique triple redundant 6-axis IMU array uses a total of 9 accelerometer and 9 rate gyro channels.

The OPENRTK330L is supported by Aceinna's Open Navigation Platform allowing custom embedded application development on top of Aceinna's proven positioning engine and dead-reckoning algorithms. OPENRTK330L hardware also includes Ethernet, UART, SPI and CAN interfaces for versatile integration into a host system. Additional specifications include operating temperature range of -40° C to +85° C, and qualification to standard automotive shock and vibration levels.
