Permanent Link to Aceinna drives to CES 2020 with tiny GNSS/INS module
Photo: Aceinna
Module designed for developers creating guidance and navigation systems for autonomous vehicles, robots, drones, industrial, construction and agricultural machinery
Aceinna launched its OpenRTK330L at CES 2020, the massive annual consumer electronics show taking place Jan. 7-10 in Las Vegas. The company is located at Booth 6738, CES North Hall, Automotive Pavilion.
OpenRTK330L is a low-cost,high-performance triple-band RTK/GNSS receiver with built-in triple redundant inertial sensors. Designed to replace the expensive and bulky precision RTK/INS systems used in today’s autonomous systems, the compact navigation solution meets the challenging performance, reliability and cost requirements of the automotive market along with the needs of robot, drone, construction and agriculture systems, Aceinna said.
Demonstration Drive
Aceinna is demonstrating its GNSS/INS-based autonomous vehicle localization technologies on its test vehicle, which drove from Silicon Valley to Las Vegas.
The company is recording live drive-test data that demonstrates how its precision positioning solutions provide high accuracy and reliability. Precision location capability is critical for all levels of autonomous driving.
OpenRTK330L includes a triple-band RTK/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 precise 2 Degree/Hour IMU to offer ten to 30 seconds of high accuracy localization during full GNSS denial. This enables autonomous system developers to safely deliver highly accurate localization and position capabilities in their vehicles at prices that meet their budgets.

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 six-axis IMU array. 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.
Open Navigation Platform
“The combination of a triple-band GNSS receiver and a high-precision IMU has enabled us to make a remarkably accurate, small, reliable and cost-effective GNSS/INS solution,” said Mike Horton, CTO of 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 Open Navigation Platform allows custom embedded application development on top of Aceinna’s positioning engine and dead-reckoning algorithms. Autonomous solution developers have full access to all resources on the OpenRTK330L module including the GNSS receiver measurement data, IMU measurement data and all interfaces.
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.
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.
