Ultra high accuracy sensor system with quick instalation, and no "initialisation" phase
The dual antenna INS systems fitted and ready in minutes, outputting data as soon as it gets a GPS lock. The dual antenna layout is favoured for industrial automotive testing where the secure temporary installation, and quick setup make efficient use of time, with exceptionaly accurate results.
SPEEDBOX-INS Tactical Dual Antenna Option
- Increased precision with tactical grade IMU
- High precision automotive speed sensor - using inertial (IMU) and GPS technology for an accurate and robust measurement.
- 200Hz on all channels, including acceleration, speed, distance, position and vehicle attitude (roll, pitch and yaw)
- Robust to GPS outages, making it ideal for on highway use as well as at the test track or racing circuit
- Simple to install and use, no complex initialisation requirements
- Dual GPS RTK (real time kinematics) antenna layout
The INS sensor assembly is connected to the main SPEEDBOX unit, where the raw inertial and GPS outputs are combined in real time to accurately measure vehicle attitude (roll, pitch, yaw), acceleration, velocity, distance, gradient and heading as well as position. All measurements have a very low latency of just a few milliseconds, and are output at a rate of 200Hz with no interpolation.
The 200Hz update rate is very important when accurately measuring vehicle responses during testing, assuring the data is accurate during dynamic manoeuvres. With such high update rates on the data it is important not to introduce noise into the system, especially when measuring velocity. The whole SPEEDBOX range is optimised for automotive testing - with the INS option offering the highest accuracy and 200Hz outputs on all channels - ensuring the update rates are as high as possible without introducing noise into the measurements.
The SPEEDBOX-INS products are suitable for detailed analysis of driver / circuit / vehicle handling, performance testing, brake and tyre testing, fuel economy, speed verification, development of driver assistance systems etc.
Typical accuracies are shown in the table below. These figures assume that a good GPS lock is available in a reasonably open environment.
