OpenRTK330L is a solution to integrate a triple-band RTK/GNSS receiver and a triple-redundant inertial sensor enhancing the safety of Autonomous Systems.

ACEINNA announced the availability of the ACEINNA OpenRTK330L, a triple-band RTK/GNSS receiver with built-in triple redundant inertial sensors. 

ACEINNA’s receiver is coupled with redundant inertial sensor arrays to provide cm-level accuracy, reliability, and performance during GNSS outages. The OpenRTK330L integrates 2 Degree/Hour IMU to offer ten to thirty seconds of accuracy localization during full GNSS denial. This enables autonomous system developers to deliver accurate localization and position capabilities in their vehicles. 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. 

The inertial measurement unit and dead reckoning function contains a total of 9 accelerometer and 9 rate gyro channels based on ACEINNA's unique triple redundant 6-Axis IMU array. By integrating a triple-redundant IMU array, the OpenRTK330L is able to recognize and utilize only valid sensor data, ensuring accurate protection limits and certifiability under ISO26262 standards.

The OpenRTK330L is supported by ACEINNA’s Open Navigation Platform allowing custom embedded application development on top of ACEINNA's positioning engine and dead-reckoning algorithms. Autonomous solution developers have access to all resources on the OpenRTK330L module including the GNSS receiver measurement data, IMU measurement data and all interfaces. 

Specifically, the OpenRTK330L GNSS receiver supports GPS (L1 C/A, L2C and L5), GLONASS (L1OF, L2OF), BeiDou (B1I, B2I), GALILEO (E1, E5a, E5b, E6) QZSS (L1 C/A), and NAVIC. The IMU sensor array includes a triple-redundant, 3-axis MEMS angular rate sensor, and a triple-redundant, 3-axis MEMS Accelerometer. The ACEINNA 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.
