Document Type and Number:
Japanese Patent JP2002536672
Kind Code:
A
Abstract:
In a satellite ranging system predetermined bit sequence or group of bit sequences in a transport stream, which is a digital signal, are used to generate trigger signals on the basis of which the delay introduced into the transport stream by the travel path from a satellite ground station to the satellite and back or to another satellite ground station is determined allowing a calculation of the distance between the ground station(s) and the satellite. The predetermined bit sequence or group of bit sequences may be inserted into the transport stream at the uplink site, for example as a specific payload P. In order to avoid insertion of additional packets the transport stream or part of it may be used as a predetermined bit sequence.
