Abstract
A system for secure communications between first and second locations wherehe first location measures the location of the second location. The first location then codes that measured location along with a random reply channel code for communications from the second location to the first location. The first location then transmits the two codes to the second location which decodes the two signals. The second location then measures it's own location and compares it with the received location. The newly measured location is coded and transmitted to the first station on the randomly selected reply channel.
