    Abstract: An method and apparatus for computing a scalar projection of a vector onto another vector. The apparatus comprises a multiplying circuit and a summing circuit. The multiplying circuit is for multiplying a value representative of a first component of a first vector with a value representative of a first component of a second vector to provide a first intermediate value, and for multiplying a value representative of a second component of a first vector with a value representative of a second component of a second vector to provide a second intermediate value. The summing circuit sums the first and second intermediate values to provide a resultant value representative of the scalar projection of the first vector onto the second vector. The apparatus may further comprise a storing circuit and a selection circuit. The storing circuit is for storing the values representative of the first and second components of the first vector, and the values representative of the first and second components of the second vector. The selection circuit provides an ordered supply of these values to the multiplying circuit.

    Abstract: A message communication system employing one or more centralized communication stations transferring messages through Earth orbit repeater satellites to or from mobile terminals with at least one central communication station having a first transceiver for transmitting a first communication signal to one or more mobile terminals and at least one mobile terminal having a second transceiver for receiving the first communication signal and demodulating it, and for transmitting at a predetermined duty cycle of the second transceiver, a second communication signal to at least one of the central communication stations. The preferred duty cycle over which the second communication signal is transmitted is about fifty percent of the second transceiver duty cycle. The communication system uses Time Division Multiplexed (TDM) communication signals using a number of channels as designated address channels with the remainder being used for data transfer. Information transmitted on the address channels is used by terminals to determine both the presence of a message and its corresponding data transmission or reception channel. In addition the terminals use the reception of the first communication signal to adjust return link transmission frequency to compensate for transmission path errors. The alternating duty cycle allows mobile terminals to use a single set of local oscillators for both transmission and reception modes of operation. To decrease interference with other systems the present system employs a power dispersal modulation function to achieve the footprint of a video signal for high transfer rate digital communication signals.

    Abstract: A method and system for determining the position of an object using a fixed station and a plurality of earth orbit satellites whose positions are known. Separate periodic signals are transmitted from the fixed station via first and second satellites to the object whose postion is to be determined. The phase offset in periodic characteristics of the periodic signals as received from the first and second satellites is measured at the object. The phase offset corresponds to a relative time difference in propagation of the signals traveling two different paths to the object. The object transmits via the first satellite a return signal indicative of the measured relative time difference. This return signal is activated some time in the future according to the object local time, which is slaved to receipt of the periodic signal sent through the first satellite. This future time is the start of the particular time period as decided by the fixed station's schedule. At the fixed station, an instantaneous round trip delay, determined by the time offset of the current transmission clock time relative to the receive clock time of reception of the return signal, along with the measured relative time difference sent back on the return signal, is used to calculate the distances between the first and second satellites to the object. From these distances the position of the object is calculated.

    Abstract: A method and apparatus for converting phase data into amplitude data. Input phase data is divided into upper and lower phase increments using an input splitter which can also fold in quadrant data. One or more storage elements, such as sine and cosine ROMs, are connected to the input splitter and generate an amplitude, which forms one of a plurality of series terms, and first and second derivatives of the amplitude in response to the upper phase increment. The first derivative and lower phase increment are multiplied together in a digital multiplier to produce a second series term. A third series term comprising a product of the amplitude and lower phase increment squared, is generated by a term generator connected to the splitter and to the storage element. The term generator can comprise elements such as a ROM addressable by the lower phase increment and the amplitude. The first, second and third series terms are subsequently added together by one or more digital adders connected to the multiplier, term generator, storage element and in series with each other to form an output amplitude. An output controller is used for transferring the output amplitude to other apparatus and for incorporating quadrant unfolding elements.
