Location tracking and positioning systems can be classified by different techniques. Which
statement is true?
A.
The ToA technique requires very precise knowledge of the transmission start times. To simplify
this technique, TDoA does not require the use of a synchronized time source at the point of
transmission, but the receivers still require time synchronization.
B.
RSS is measured by either the mobile device or the receiving sensor. Knowledge of the
transmitter output power allows you to calculate the distance between the two stations.
C.
A common benefit of AoA compared to the other location tracking techniques is its susceptibility
to multipath interference, which allows several angle calculations and therefore very accurate
positioning.
D.
The LTP field in the CCX Payload information allows synchronization between transmitter and
receivers to allow calculation of the position within 10 meters during 90 percent of the time.
