Abstract
A method of determining the position of a plurality of a radio transmitter units relative to a master unit is disclosed in which a control signal is provided from the master unit commanding each of the radio transmitter units to transmit a test signal and the remaining units to receive. The arrival times of the test signals are measured at the receiving radio transmitter units, and the position of each radio transmitter unit relative to the master unit is calculated solely on the basis of the measured arrival times, and an approximate initial position for each unit.

A method of determining the position of a plurality of a radio transmitter units relative to a master unit comprising the steps of:
- providing a control signal from the master unit commanding each of the radio transmitter units to transmit a test signal and the remaining units to receive;
- measuring the arrival times of the test signals at the receiving radio transmitter units;
- and
- calculating the position of each radio transmitter unit relative to the master unit solely on the basis of the measured arrival times, and an approximate initial position for each unit.
A system for position monitoring comprising:
- a master unit;
- and
- a plurality of radio transmitter units, wherein the master unit includes means for providing a control signal commanding each of the radio transmitter units to transmit a test signal and the remaining units to receive;
- the system further comprising means for measuring the arrival times of the test signals at the receiving radio transmitter units and means for calculating the position of each radio transmitter unit relative to the master unit solely on the basis of the measured arrival times and an approximate starting position for each radio transmitter unit.
