One or more cameras or microphones or data signal generation devices, storage devices, and processors for recording or storing and processing of signals obtained from one or more cameras or microphones or data signal generation devices. A processor for processing input signals and for providing cross-correlated shaped in-phase and quadrature-phase baseband signals. Transceivers for multimode GSM, spread spectrum, CDMA, OFDM, TDMA and other signals. A receiver and demodulator for reception of modulated position finder radio frequency (RF) signals transmitted by a Global Positioning System (GPS) transmitter and a receiver and demodulator for reception of modulated position finder radio frequency (RF) signals transmitted by other than a GPS transmitter for providing the demodulated and receiver processed signal to an emergency unit.
An air based position finding, signal monitor, control and emergency multimode communication system for use in one or more units located in or on airplanes, or helicopters, or unmanned vehicles (UV) or balloons or rockets, or missiles, or space shuttles or birds or other air based items with a multimode bit rate agile (BRA) and modulation demodulation (modem) format selectable (MFS) signal modulator.
