Precision reference

Record a complete 3D motion and dynamics profile with the GNSS + inertial sensor fusion. The RT3000 provides smooth, robust and repeatable outputs in real-time with low latency. The fully integrated high-grade MEMS IMU and RTK capable GNSS receivers record a comprehensive list of measurements including position, velocity, acceleration, and orientation.

Maximum repeatability

When performing complex test scenarios such as slalom lane changes or multi-vehicle ADAS tests, repeatability is important to be able to properly verify the results. Driving robots for steering, throttle and braking control are often used to eliminate any potential variations from human drivers. The RT3000 can connect with driving robots such as AB Dynamics via Ethernet to provide accurate path following capability.

Fit your budget and application

A range of model variants and upgrades to choose from ensures there’s always an RT product suitable for you. The RT3100 series offers a lower cost option when high dynamic motion analysis is more important than absolute position accuracy. The RT3002 has RTK functionality for centimetre-level accuracy. Options such as dual antenna (RT3003), GLONASS, CAN acquisition and increased output rate can be added at any time so if your requirements change, the RT3000 upgrade path can save reinvesting in a completely new system.

Reliable data in difficult environments

Open-road testing faces issues of limited GNSS in urban canyons, under tree cover and obstructions such as bridges and tunnels. Supporting technologies in the RT3000 help maintain the best possible performance in all environments. Minimise position drift during outages with combined forwards/backwards processing in our free post-processing application NAVsolve. Add a wheelspeed odometer for extra velocity updates in the Kalman filter to help when stationary or slow moving. 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.

One box, turnkey solution

One tool to combine multiple functions, no need to complicate tests with many separate pieces of equipment. The RT3000 integrates GNSS, IMU, onboard data logging, real-time processing and with the CAN acquisition upgrade can become a central data acquisition system for other CAN signals from the vehicle such as steering angle and throttle position.

Take to the open roads

Testing in controlled environments such as proving grounds with a permanent base station and a radio link to transmit differential corrections to the RT3000 is straightforward enough. But NTRIP and Terrastar-C support make it easier than ever to venture out on the open roads. Corrections are supplied via satellite or mobile data connection meaning you aren’t tied to a base station and can still achieve centimetre-level accuracy.
