Remote Controlled (RC) air based communication systems and methods for aircraft such as airplanes, helicopters, Unmanned Vehicles (UV), balloons and other objects in air based devices. Air based communication devices receive modulated signals from GPS satellites, or other satellites or from land based or in or on water or air based transmitters and demodulate and process these signals into location finding information. A photo camera or video camera generated signal is processed with location finding information and the camera generated signal with the location finding information is processed in an OFDM processor or in a spread spectrum processor. The spread spectrum processor provides cross-correlated in-phase and quadrature phase processed signals. The OFDM processed and the cross-correlated processed signals are modulated and transmitted. A received RC signal and/or a motion detector is used for control of operation of air based devices. Infrared transmitters, smoke and heat/sensor devices are implemented in the airborne devices. The airborne device, in a repeater mode receives and demodulate a first OFDM modulated signal into an OFDM baseband signal. The OFDM baseband signal is subsequently modulated into a second OFDM signal and is transmitted from the airborne device. The communications and control of air based devices is in land based cellular systems (e.g. WCDMA, CDMA, GSM, 3G, 4G and 5G), wireless mobile internet networks, Bluetooth and satellite systems. |

1. A method comprising steps of:
receiving and demodulating in an air based device a Global Positioning System (GPS) modulated signal; demodulating said GPS modulated signal into a demodulated GPS baseband signal; generating in said air based device a photo camera generated baseband signal; modulating in said air based device, in a modulator said demodulated GPS baseband signal processed with said photo camera generated baseband signal, said GPS demodulated baseband signal processed with said photo camera generated baseband signal comprises spread spectrum cross-correlated in-phase and quadrature-phase Time Constrained (TCS) waveform and cascaded Long Response (LR) filtered baseband signals, into a cross-correlated modulated signal; transmitting from said air based device said cross-correlated modulated signal; receiving in said air based device a modulated remote control (RC) signal; demodulating said modulated RC signal into a demodulated RC signal; processing said demodulated RC signal into a processed RC signal; and providing said processed RC signal to a processor and control unit, of said air based device, for control of the operation of said air based device. |
