  • System and method to communicate time stamped, 3-axis geo-position data within telecommunication networks
    Patent number: 6144336
    Abstract: In the case of a conventional radio telecommunication system for transmitting information between stationary transmitting/receiving units and mobile transmitting/receiving units it is proposed that the mobile units be additionally provided with a satellite navigation receiver for independently determining a position rough value. The stationary units are likewise provided with a satellite navigation receiver for independently determining a reference position rough value of a reference location of known exact geographical position as the reference position normal value, and with an error detection unit for detecting position determination errors by comparing the instantaneously determined reference position rough value with the reference position normal value.
