- OpenRTK330L integrates a triple-band RTK/GNSS receiver and a triple-redundant inertial sensor enhancing the safety of autonomous systems
ACEINNA recently released the ACEINNA OpenRTK330L.It is a low cost and high-performance triple-band RTK/GNSS receiver. It features built-in triple-redundant inertial sensors. The receiver is designed to replace the expensive and bulky precision RTK/INS systems. This compact navigation solution meets the challenging performance, reliability and cost requirements of the automotive market.
Works on inertial sensor arrays
The triple-band RTK/GNSS receiver is coupled with redundant inertial sensor arrays. It provides cm-level accuracy and enhanced reliability during GNSS outage. Both these characteristics promise superior performance to the system. The OpenRTK330L integrates a very precise 2 Degree/Hour IMU.
This IMU offers ten to thirty 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. This solution is offered at budget-friendly prices.
OpenRTK330L’s embedded Ethernet interface allows easy and direct connection to GNSS correction networks around the world. The RTK’s CAN bus interface allows simple integration into existing vehicle architectures.
Mike Horton, CTO of ACEINNA, said in an interview that,
“ 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. 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. ”
Can track up to 80 different channels
The multi-band GNSS receiver can monitor all global constellations (GPS, GLONASS, BeiDou, Galileo, QZSS, NAVIC, SBAS). It can track up to 80 channels simultaneously over a network. The module offers RF and baseband support for the L1, L2, and L5 GPS bands.
Unique 6-axis IMU array
The inertial measurement unit contains a total of 9 accelerometer and 9 rate gyro channels. All these sensors are 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. This ensures high-accuracy against protection limits. The receiver features certifiability under ISO26262 standards.
Runs dead reckoning algorithms
The OpenRTK330L is supported by ACEINNA’s Open Navigation Platform. It allows custom embedded application development on top of ACEINNA’s positioning engine and dead-reckoning algorithms. Autonomous solution developers can have full access to all resources on the OpenRTK330L modules. This access includes functions used to measure GNSS receiver data, IMU data and all interfaces.
Can work for temperatures up to 85° C
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. It also includes a triple-redundant, 3-axis MEMS Accelerometer.
The ACEINNA OpenRTK330L hardware also includes Ethernet, UART, SPI and CAN interfaces. It provides a versatile integration into a host system. Additional specifications include operating temperature range of -40° C up to 85° C. Additionally, it qualifies to industrial standards focusing on automotive shock and vibration levels.
