Using preciseness timing , they cypher out how far a TV signal travels before it is picked up by a twist equipped with Rosum chips . Next , they compare the measurements against other data that they collect with their own hearing place and then finally calculate the equipment ’s location .
Since the Rosum answer ca n’t determine altitude , and obviously wo n’t work where there are n’t TV signals , the answer is best used when mate with a traditional GPS system .
