摘要： A communication system and method for transmitting data to mobile platforms using multiple simultaneous channels operating at multiple data rates. Each mobile receiver has the capability to receive multiple transmit channels at multiple data rates. Mobile platforms report their position to a ground based controller which determines which communication channel can be operated without substantial loss of data. Data packets destined for each aircraft are preferably routed to the highest data rate channel that can be received by that mobile platform without substantial loss of data. This maximizes the overall system efficiency and throughput. High priority and mission critical data may be transmitted to the aircraft using low data rate channels to increase link availability.

摘要： A polling system and method for establishing forward and return communication links with a plurality of mobile platforms operating within a given coverage region, and further which provides preliminary return channel assignments with each polling message. Each polling message further has an associated ID code designating a particular mobile platform which is registered with a network operations center (NOC) of the system. If the mobile platform does not respond on its designated preliminary return channel within a given time period (e.g., 5 seconds) than the preliminary return channel is returned to a database of available return channels. Polling is carried out more expeditiously because groups of mobile platforms are polled simultaneously and provided with preliminary return channels which accompany the polling messages, and which direct each mobile platform to a designated return channel to use in establishing a return communications link. Polling groups are further sized according to available communication resources.

摘要： A system and method for quickly detecting and remedying an interference incident caused by one of a plurality of mobile terminals in communication with a transponded satellite. The method makes use of a time line constructed from communications of each of the mobile terminals. The time line forms a real time, sequential record of events wherein various mobile terminals have made contact with the transponded satellite. The method extrapolates from the time line which one of the mobile terminals has caused an interfering event by determining which mobile terminal accessed the communication system just prior to the interference event arising.

摘要： A method for rapidly monitoring and detecting a mobile terminal causing RF interference with one or more satellites orbiting in the vicinity of a target satellite, from a plurality of mobile terminals accessing the target satellite. Each mobile terminal performs a transmit lobing signal sequence and a ground-based component in the form of a Network Operation Center (NOC) analyzes the signals transmitted by each mobile platform. The NOC determines a ratio of energy-per-bit to noise spectral density (Eb/No) value for the signals transmitted by each mobile platform and compares these values to a predetermined Eb/No value. If the Eb/No values for a given mobile platform deviate by more than a predetermined magnitude from the predetermined Eb/No value, then the NOC identifies that given mobile platform as causing the unintended RF interference with the adjacent satellite(s).

摘要： An optical sensing system for sensing the temperature at a first location, including: electro-optical unit for producing a modulated optical signal and a light guide unit for receiving and transmitting the modulated optical signal along an optical path. The optical system further includes temperature sensing fiber which receives and guides the modulated optical signal along a temperature sensing optical path. One portion of the modulated optical signal serves as a reference optical signal and another portion of the modulated optical signal serves as a target optical signal. The optical sensor system also has a transducing unit, which receives the reference optical signal, the target optical signal having first and second time delays with respect to a chirped rf signal from the electro-optical unit. The transducing unit produces a multi-frequency electrical signal which includes a first frequency corresponding to the first time delay a second frequency corresponding to the second time delay. The optical sensor system further has a temperature detecting means coupled to the output of the transducing unit which processes the multi-frequency signal and determines a difference frequency corresponding to the temperature at the first location.

摘要： The optical receiver has a photodiode (10) which is reverse biased by a voltage supply (14). The voltage supply provides a variable bias voltage determined by a control unit (16) and the photodiode is matched to the load (22) by an impedance matching circuit (12). The photodiode exhibits large capacitance changes over a range of bias voltages and may be implemented using a Schottky barrier or P.sup.+ N photodiode. By changing the bias voltage, the photodiode capacitance changes to vary the tuned frequency of the receiver. The matching circuit cancels the reactive component of the photodiode impedance and matches the resistive component to the load. The photodiode may have a doping profile in which an intrinsic or lightly doped region of width greater than the average photon penetration depth is located next to the junction. After the intrinsic region, the doping profile may be selected to achieve linear tuning. This doping profile gives linear tuning without sacrificing photodiode conversion efficiency.
