Fully integrated miniature dual antenna GNSS/INS, ideal for space constrained ADAS applications such as low-profile robotic platforms, pedestrian and VRU tests.

 - Used for NCAP AEB VRU tests where size and weight are critical
 - Tightly-coupled GNSS/IMU for reliable accurate measurement
 - Up to 2 cm position accuracy, 0.25° slip angle accuracy
 - Dual antenna GPS/GLONASS for accurate heading in all conditions
 - One box solution with real-time CAN, Ethernet and serial output


No compromises

Despite its small size, the RT1003 integrates high-grade MEMS inertial sensors and RTK capable GNSS receivers. This allows it to be economical on price and power but still deliver centimetre-level positioning and accurate velocity, acceleration, and orientation that is required by NCAP, NHTSA, and IIHS tests.

Maximum performance

When GNSS struggles, such as in open-road testing where tunnels and bridges can cause obstructions, the high-grade MEMS IMU provides a backup to fill in the gaps and keep the system on track. Supporting technologies such as odometer input, forwards/backwards processing, and vehicle motion profiles help maintain best possible accuracy that’s smooth and free from jumps in all environments. Ensure as much of your data as possible is within spec with our gx/ix tight-coupling technology, which speeds up RTK reacquisition times and can maintain RTK level performance even in high multipath environments and poor satellite visibility.

An INS and a data acquisition system in one box

As well as the integrated GNSS and IMU, the RT1003 has internal data logging and optional CAN acquisition, so all vehicle information can be logged in one place.

Compatible with the RT-Range S Target

The RT1003 is the ideal choice if you’re looking for an INS for a moving ADAS target including in Euro NCAP AEB C2C and VRU tests. Using the RT-Range S Target, you can connect the device to an RT-XLAN W-Fi antenna Target and transmit data from the RT1003 in your target vehicle/platform to the RT in the Hunter vehicle

Improve productivity

Installation and configuration is made easy with simple and intuitive software wizards to speed up the process. For permanent installations, set it up once and you never need to touch it again, letting you focus completely on the task at hand. The free software suite includes real-time monitoring for instant verification so you can spend more time testing and less time checking. Thanks to advanced temperature calibration, the system is fully optimal after just a few minutes warm-up.
