| 摘要 |
The invention refers to a location method and location apparatus for determining the location of a stationary satellite receiver having a stationary satellite antenna by means of ranging packets within satellite payload signals. Said satellite payload signals are transmitted from one or more earth stations at defined earth station positions and are relayed from one or more satellites at different geostationary orbital positions to be received by the same stationary satellite antenna, wherein each ranging packet within the corresponding satellite payload signal is related to a time stamp information with regard to the point of time when the ranging packet was transmitted from the corresponding earth station, and wherein a plurality of the ranging packets is detected by the stationary satellite receiver in the received satellite payload signals, wherein the relative time differences between the points of time of detection of the corresponding ranging packets are measured and wherein the measured relative time differences are collected and are related to the defined earth station positions, the time stamp information and the satellite position information for estimating the location of the stationary satellite receiver by means of a secondary condition for resolving the redundancy of the measured relative time differences.
