1. An air based position finding, signal monitor, control, emergency and multimode communication system comprising:

  • a receiver having multiple inputs for reception and demodulation of position finder signals to position finder baseband signals;

    one or more cameras or microphones or data signal generation devices, storage devices, and a first processor for recording or storing and processing of signals obtained from one or more cameras or microphones or data signal generation devices;

    a second processor for processing input signals and for providing cross-correlated shaped in-phase and quadrature-phase baseband signals;

    a third processor for receiving input signals and for providing filtered baseband signals;

    a fourth processor for processing the first processor processed signals jointly with cross-correlated signals or jointly with filtered signals or jointly with both cross-correlated signals and spread spectrum signals;

    a control unit for control and selection of one of the jointly processed signals;

    a selector for providing the selected signal to a modulator;

    a signal modulator for modulating the selected signal and for connecting the modulated signal to a signal transmitter for signal transmission;

    a communication receiver for reception, demodulation and processing of the modulated transmitted signal;

    a demodulator for demodulation and receiver processing of the modulated transmitted signal; and

    a receiver processor for providing the demodulated and receiver processed signal to an emergency unit or to one or more subscriber units or to both emergency and subscriber units.
