A terrestrial positioning system includes a mobile terrestrial transmitter including a local clock source and an inertial measurement unit, and a synchronization master including a memory configured to store initially known positioning information of the terrestrial transmitter. The terrestrial transmitter determines altered positioning information of the terrestrial transmitter using the first IMU and broadcasting a positioning signal including a timestamp. The synchronization master calculates an expected time of flight of the received positioning signal based on the determined altered positioning information and the stored initially known positioning information of the terrestrial transmitter, to determine a first deviation of the actual time of flight determined from the timestamp and the actual reception time of the received positioning signal with respect to the calculated expected time of flight and to instruct the terrestrial transmitter to delay or prepone the broadcast of the positioning signal.
