Limited Satellite Contact
WARNING: This page is about a different car, the 2013 Land Rover LR4, 2012 Land Rover LR4, 2011 Land Rover LR4, and 2010 Land Rover LR4. However, it is still accessible from the selected car via links, so may be relevant.
It is possible to maintain the vehicle's positional information when there is limited or no satellite contact, for example when the vehicle is in a:
- Tunnel or underpass
- Covered car park
- street lined with tall buildings
- or dense forest.
When the vehicle is in one of these conditions the vehicle's position is maintained by both the gyroscope sensor contained in the TSD and the vehicle speed signal. The speed signal is supplied by the ABS module and transmitted via the high-speed CAN to the CJB it is then transmitted by a hard-wired signal to the TSD.
