Aceinna launches high-precision GNSS/INS localization solution
Aceinna announced the availability of the new Aceinna OpenRTK330L, a low cost and high-performance triple-band RTK/GNSS (Real Time Kinematics/Global Navigation Satellite Systems) receiver with built-in triple redundant inertial sensors. Designed to replace the current RTK/INS systems used in today’s autonomous systems, this compact navigation solution was created to meet the challenging performance, reliability, and cost requirements of the automotive market along with the needs of robot, drone, construction, and agriculture systems.
“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 ACINNA's open-source, developer-friendly Open Navigation Platform.”
Aceinna’s OpenRTK330L includes a triple-band RTK/GNSS receiver coupled with redundant inertial sensor arrays to provide accuracy, reliability, and performance during GNSS outages. The OpenRTK330L integrates a precise 2 Degree/Hour IMU (inertial measurement unit) to offer 10 to 30 s of high accuracy localization during full GNSS denial. This aims to enable autonomous system developers to safely deliver accurate localization and position capabilities in their vehicles at prices that meet their budgets, says the company. OpenRTK330L's embedded Ethernet interface allows easy and direct connection to GNSS correction networks around the world. According to the company, OpenRTK330L's CAN bus interface allows integration into existing vehicle architectures.
Aceinna says that 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 nine accelerometer and nine rate gyro channels based on Aceinna's triple redundant 6-Axis IMU array. By integrating a triple-redundant IMU array, the OpenRTK330L is reportedly able to recognize and utilize only valid sensor data, ensuring high-accuracy 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 full 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 -40°C (-40°F) to +85°C (185°F), and qualification to standard automotive shock and vibration levels.
