To cover for losses in satellite visibility most OEM navigation systems have a dead reckoning capability. This utilises vehicle wheel speed data and rate of turn 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 however, if the dead reckoning signals are not present the navigation unit will not function correctly.
To overcome these obstructions we have developed a full navigation testing solution. Watch the video below to see how it works.
