Abstract: The satellite radio communication system of this invention provides communication between one or more service centers and an ensemble of fixed and mobile user terminals. One or more earth orbiting satellites are provided with each satellite having transmitter forming a down-link channel which is slow frequency hopped, and a multi-beam antenna system with a single channel per beam to time division multiple broadcast signals to all user terminals covered by each said beam, respectively. Each user terminal includes a transceiver for receiving a down-link channel broadcast from the one of said beams in whose path it lies, and a return link comprised of a dedicated narrow band broadcast channel with slow frequency hopping of down-link channel. There is a fixed set of frequencies through which the frequency hopping is carried out, with the plurality of fixed and mobile user terminals using the same set of frequency hopping frequencies. Mutually synchronized transmissions from each user is such that while the ensemble of users display the same set of frequency hopping frequencies, each user in said ensemble of fixed and mobile user terminals employs a unique frequency at each instant of time.

Abstract: The present invention relates to a no outage GPS/AM position finding system wherein a GPS system having a plurality of satellites transmits time and location data over radio frequency signals to enable a mobile GPS receiver station on the ground to determine its position, and a cellular telephone is carried with the mobile GPS receiver, traveling in range of a plurality of conventional ground based amplitude modulated (AM) transmitters for transmitting AM signals. Each mobile GPS receiver station includes phase detection means for simultaneously receiving a predetermined number of the AM signals, and measuring the changes in phase of each of the AM signals as the mobile GPS receiver travels, and deriving therefrom an AM position signal. A reference station for receiving the GPS and AM signals provides correction signals via a cellular telephone network which receives and transmits the correction signals to the mobile GPS receiver station. The last accurate GPS position signal is used for resolving any ambiguities in the AM radio position signal and to accommodate the lack of synchronization in the AM transmitters. The reference station measures the frequency and wavelength variations in the AM signals and conveys same to the mobile GPS receiver station by the cellular telephone. The AM position signal is activated upon detecting outages or blockages in the GPS signals.

Abstract: A communications system operating in one or more frequency bands of various number of channels per band (for a total of N channels), and a novel transceiver for receiving these multiple bands of signals. The transceiver comprises an antenna and RF front end for each said band, a separate RF to IF downconverter for each said band. The IF for each band is centered at a succession of frequencies Fo such that the spectra for each band are non-overlapping, with the center frequencies. Analog-to-digital converter sampling rate is chosen such that one band is centered at baseband, and one or more other bands are centered at a specific relationship with the sampling rate such that each band is individually downconverted to baseband by appropriate selection of tap weight multiplying sequences (such as alternating +/− sequence for the case of Fo equal to one-fourth the sampling rate). An analog-to-digital converter converts analog signals to digital signals from the combiner. A digital downconverter converts the digital signals to baseband signals and a single digital processor sequentially time shared among all the bands and channels.

Abstract: An existing TDRSS satellite communication system is incorporated, together with low-power ground-based remote transceivers of special design, and additional beam forming and steering elements at the ground terminals, to make possible digital communication between low power field transceivers and satellite ground terminals. The satellite communication system transmits to its ground terminals a composite signal, comprising amplified, phase-coherent signals received by an array of broad-coverage antennas on the satellite. The field transceiver transmits a pseudonoise coded signal spread across all or a portion of the satellite's receive bandwidth. At the ground terminal, the downlinked composite signal is processed by a beamformer to define a narrow, high-gain beam between the satellite and low-power transceiver. Signal processing gain and beamformer gain in combination serve to elevate the received, demodulated signals well above the noise level at the receiver. Through this invention, a large multiplicity of non-interfering reverse-link (remote-to-central) narrow-band communication channels may be supported by a host satellite communication system of the nature described. By the introduction of forward link signal channels into the satellite ground terminal, and scheduling of forward link transmissions to the set of low-power remote transceivers along with normal transmit activities, highly useful two-way communication can be extended to a class of users not initially served by the satellite communication system.

Abstract: A radio transmitter having a source of first signals for radio transmission, includes a modulator for modulating the first signals on an intermediate carrier frequency second signal to produce a third signal. A charge coupled device (CCD) is connected to receive and process the third signal in the absence of digital waveform shaping and digital-to-analog conversion. The CCD has a sampling rate which is a multiple of the intermediate carrier frequency second signal to provide aliased fourth signal components that are spectrally spaced in accordance with the multiple and provide upconversion to a fifth signal. A bandpass filter receiving the fifth signal is centered around a selected aliased signal component and a power amplifier/antenna means coupled to receive said selected aliased component for transmission. In a preferred embodiment, the multiple is 4. Moreover, the tap weights of the CCD are selected to provide wave shaping of the aliased fourth signal components. A transceiver including the radio transmitter has a radio receiver, with the radio receiver having a CCD signal processing circuit for receiving and demodulating received radio signals.
