To cover for losses in satellite visibility most OEM navigation systems have a dead reckoning (DR) capability. This utilises vehicle wheel speed data and turn rate information to provide the system with a guide to the vehicle’s current location when GPS signals are not available. When it comes to testing these systems on the bench if the dead reckoning signals are not present, the navigation unit will not function correctly.

Watch the video below to see how our system can be used to test your device in the absence of GPS >

Many navigation systems now use dead-reckoning information such as vehicle speed, gyro and acceleration sensors to assist navigation when GPS is not available. This information is usually obtained from one of the vehicle’s CAN Bus networks.

Our new Dual CAN Bus Interface module for LabSat 2 allows users to accurately reproduce two CAN Bus networks as well as the GPS signal in a lab environment. Utilizing the digital input capture mode of LabSat 2, this module makes it possible to simultaneously record a live GPS signal and two separate CAN Bus signals, repeatable to within 60 nanoseconds.

The module digitizes the CAN Bus signals at over 16MHz, allowing every message to be recorded, even if the CAN buses use different baud rates.

We have recently completed work on a range of new software features for LabSat. These include:

Transmission of wheel speeds via CAN
In addition to simulating wheel speed pulses, LabSat now includes the ability to transmit wheel speeds via CAN when replaying SatGen scenarios. When used in conjunction with a turntable – to simulate a vehicle turning - this gives you a complete dead reckoning test system.

Simultaneous display of GPS and GLONASS signals
The GPS monitor built in to LabSat 2 has now been upgraded to support an optional GPS & GLONASS module. This allows the software to display signal levels for both constellations during replay.

This February we will be exhibiting at both the Mobile World Congress in Barcelona between the 25-28th and Embedded World in Nurnberg on the 25-27th February 2013.

At the shows we will be demonstrating how LabSat can be used to test navigation and telematics devices, as well as showing you how LabSat 2 can now be used to test devices using the new Chinese BeiDou constellation.

Mobile World Congress 2013 will be attended by Julian Thomas and Mark Sampson from our UK office, whilst our stand at Embedded World will be attended by Chris Smith and Leander Speth, our Sales Director for Europe and Asia.

If you are attending either of these shows feel free to come by our stands and say hello. We will be happy to discuss any testing requirements you may have.

Mobile World Congress – Hall 7, Stand A60

Embedded World – Hall 4, Stand 519
