Verfahren zur kontinuierlichen Echtzeitverfolgung der Position von wenigstens einem mobilen Objekt sowie zugehoerigen Sendern und Empfaengern

WO2004038448 A UPAB: 20040608 NOVELTY - Time-division multiplexed electromagnetic signals from a transmitter in the mobile object are received by a stationary receiver and analysed by processing device. The available frequency band is used as a single channel for maximizing positioning accuracy. The communication between transmitters (S, Sp, Sb) and receivers (E1,...En) is based on pseudo-random time-division multiplexing with non-synchronized pseudo-random patterns. The transmission signals of different transmission bursts are characterized with low cross-correlation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an apparatus for transmitting electromagnetic waves for use in the method. USE - E.g. for tracking the position of footballs, tennis or golf balls. ADVANTAGE - Very high spatial resolution, and a temporal resolution of a few milliseconds
