The RT2000 family products are advanced, precision Inertial and GNSS Navigation systems for measuring motion, position and orientation. They use Inertial Navigation System (INS) technology and combine this with GNSS receivers. The best attributes of Inertial Navigation Systems and GNSS are blended together to give an optimum solution. The systems improve the performance over GNSS-only ones by providing accurate velocity in urban or tree-covered environments. The drift common to conventional Vertical Reference Units (VRU) or Stabilized Platforms is corrected automatically so that the RT2000 family products can be used indefinitely without drifting or needing to be reset.
The outputs from the RT2000 Inertial and GPS Navigation System are derived from the measurements of the accelerometers and gyros. Using the inertial sensors for the main outputs gives the RT2000 system a fast update rate and a wide bandwidth. The RT2000 is available with an update rate of 100Hz or 250Hz.All the outputs are computed in real-time with a very low latency.
The RT2000 Inertial and GNSS Navigation System outputs the real-time measurements over RS232, Ethernet and CANbus. Optional outputs can be made over Analogue. The Analogue option, the RT-ANA, includes 16 individually configurable channels of 16-bit resolution. Galvanic isolation on the analogue outputs ensures there are no ground loops. The CAN bus output can be combined into a vehicle’s CAN bus or captured using any CAN data acquisition system. The real-time nature allows the RT2000 to be used for hardware in the loop and controller development. Connection to powerful tools like dSPACE is easy. CAN DBC files are provided.
The precision ADC in the RT2000 gives more than 20 bits of resolution. The resolution of the acceleration measurements is 0.12mm/s² (12uG). The ADC oversamples the analogue sensors and uses coning/sculling motion compensation algorithms to avoid aliasing of the signals.The internal processing includes the strapdown algorithms (using a WGS-84 earth model), Kalman filtering and in-flight alignment algorithms. The internal Pentium-class processor runs QNX real-time operating system to ensure that the outputs are always delivered on time. The Kalman filter monitors the performance of the system and updates the measurements using GNSS. By using the measurements from GNSS, the RT2000 is able to maintain highly accurate measurements and correct inertial sensor errors.
The RT2000 Inertial and GNSS System comes with acquisition software that collects the data on a PC or on Pocket PC devices. The software can be used to save tests in files, display real-time results and monitor the performance. The internal logging enables the RT2000 range of products to work stand-alone. Post-mission, data can be output in ASCII text format and loaded in to the software of your choice. Simple configuration software allows the user to change the mounting angle; displace the measurement point to a virtual location; change the differential GNSS options and many more.
True Lateral Acceleration
2 GB Logging
5 min installation
Upgradeable to Dual-Antenna
Testing Even during dynamic tests, GNSS and inertial measurements at 100 or 250 Hz give a complete and accurate picture of how a vehicle is moving.
Slip Angle Measurement
Slip-angle measurements accurate to 0.2° at just 50 km/h and accurate roll and pitch measurements provide the detail you’re looking for.
Capture your data in a reliable and repeatable way with high accuracy acceleration measurements in all axes, wheel speed and brake trigger inputs.
Two-centimetre accuracy, multiple slip-point measurements and precise roll/pitch measurements capture exactly how the vehicle responds on different tyres.
The RT2000 can capture the data required for modelling control systems, and then validate the results in real-world tests.
ADAS testing (with RT2002)
RT sensors are already widely used in ADAS development and validation because their accurate and repeatable measurements provide the information engineers need.
