The company with research and development facilities in Andover (MA), San Jose (CA), and Chicago (IL) as well as manufacturing facilities in Wuxi, China has announced the OpenRTK330L gateway. It is a triple-band RTK/GNSS receiver with built-in triple redundant inertial sensors. Designed to replace RTK/INS systems used in today’s autonomous systems, this navigation solution meets the performance, reliability, and cost requirements of the automotive market along with the needs of robot, drone, construction, and agriculture systems, said the company.

“The combination of a triple-band GNSS receiver and a high-precision IMU (inertial measurement unit) has enabled us to make a remarkably accurate, small, reliable and cost-effective GNSS/INS solution,” explained Mike Horton from Aceinna. “The OpenRTK Precise Positioning Engine optimizes satellite tracking and high RTK fixes rates while integrating seamlessly with Aceinna's open-source, developer-friendly open navigation platform.”

The triple-band RTK/GNSS receiver is coupled with redundant inertial sensor arrays to provide cm-level accuracy. The device integrates a 2-degree/hour IMU to offer ten to thirty seconds of accuracy localization during GNSS denial. This enables autonomous system developers to safely deliver accurate localization and position capabilities in their vehicles. The embedded Ethernet interface allows direct connection to GNSS correction networks around the world. The CAN interface enables integration into the in-vehicle network architecture.

The multi-band GNSS receiver can monitor global constellations (e.g. GPS, Glonass, Beidou, Galileo, QZSS, Navic, and SBAS). It tracks simultaneously 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 IMU and dead reckoning function contains a total of nine accelerometer and nine rate gyro channels based on the company's unique triple redundant 6-axis IMU array. By integrating a triple-redundant IMU array, the receiver is able to recognize and utilize only valid sensor data, ensuring protection limits. It meets also the safety requirements of ISO 26262.

The receiver is supported by Aceinna’s Open Navigation Platform allowing custom embedded application development on top of the positioning engine and dead-reckoning algorithms. Autonomous solution developers have access to all receiver resources including the GNSS receiver measurement data and IMU measurement data. Besides CAN and Ethernet, the receiver also features SPI and UART connectivity. The product is qualified for operating temperatures from -40 °C to +85 °C, and automotive shock as well as vibration levels.
