3.4 ADR Navigation
The Automotive Dead Reckoning feature (ADR) of the R&S TSMX-PPS2 provides
100 % navigation coverage even in tunnels or building canyons with bad or missing
GPS coverage. ADR combines the calculated GPS position data with heading and
distance data from additional sensors. When GPS satellites are out of sight, the last
valid position is extrapolated using distance and angle information from a gyroscope
and a speed/direction pulse input.
It is also possible to use the time synchronization output in this mode.
The gyroscope for heading information is already embedded in the R&S TSMX-PPS2.
The distance signal and the direction information need to be derived from the vehicle
tachometer pulses and direction indication and fed via the accessory sensor cable into
the SENSOR IN port. Power supply and data connection are provided via the USB
cable.
