In GPS-based RF transmission, mobile wireless camera systems continuously send their position via GPS to a central receiving unit, for example in the RF production vehicle HDwireless RF1. There, the signals of all GPS transmitters in use are recorded and evaluated. This technology is used, for example, when using the HDwireless GPS antenna tracker. Here, the antennas of the tracker are constantly aligned on the locations of the transmitting wireless cameras, for example at major sports events such as cycle racings or marathons. The “Traveled Path Recording” continuously records all GPS positions for analysis in ongoing production and displays them in a geographical map. Using Web Access, the current production data is made available via internet for a transparent monitoring.
