Aceinna is now shipping its OPENRTK330L, a cost-effective module designed for developers creating mission-critical guidance and navigation systems for autonomous vehicles, including robots, drones, industrial, construction and agricultural machinery.

Aceinna designed the OPENRTK330L to replace expensive and bulky precision RTK/INS systems used in today’s autonomous systems.

The OPENRTK precise positioning engine optimizes satellite tracking and high RTK fixes rates while integrating seamlessly with Aceinna’s open-source Open Navigation Platform.

In January 2020, the Aceinna test vehicle drove from the Bay Area to the CES 2020 event in Las Vegas using the new module. Along the way, Aceinna engineers tracked its path and accuracy.

ACEINNA’s OPENRTK330L includes a triple-band RTK/GNSS receiver coupled with redundant inertial sensor arrays to provide centimeter-level accuracy, enhanced reliability and superior performance during GNSS outages. It integrates a precise 1.5-degree/hour inertial measurement unit (IMU) to offer 10 to 30 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. OPENRTK330L’s 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 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 the 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 -40C to +85C, and qualification to standard automotive shock and vibration levels.
