Abstract: A new approach for designing satellite constellations whereby each satellite follows a common ground track is being proposed for performing high-precision change detection imagery for long periods of time. By precisely prescribing the orbital parameters, i.e., the relationship between the right ascension of the ascending nodes (RAAN) and the phase angle difference between successive satellites, for example, sharpened change detection images may be taken from successive satellites in the constellation without the need to process out blurring by any special image re-working software. The relationship between the orbital parameters of the satellites is precisely tuned to the earth's rotation rate for the altitude of the satellites. A reduction in the total satellite count is achievable due to tiling the satellite coverage in near optimal arrangements.

Abstract: A new approach for designing satellite constellations whereby the satellites are distributed into contiguous groups forming longitudinal lengths at least equal to 360 degrees. Gaps between the contiguous groups are uniformly distributed along the tracks. These contiguous groups of satellites may be populated by having multiple satellites onboard a single launch vehicle, whereby the satellites are nested into multiple common ground track sub-constellations to form a constellation with multiple common ground tracks.

Abstract: A new method of constellation design based on combining repeating ground tracks with common ground tracks and/or sun-synchronous orbits is used for performing high-precision change detection imagery for longer periods of time while minimizing battery usage. By precisely prescribing the orbital parameters, sharpened change detection images may be taken without the need to process out blurring by any special image re-working software. The relationship between the orbital parameters of the satellites is precisely tuned to the earth's rotation rate for the altitude of the satellites. The unique set of earth orbits minimizes satellite battery requirement while optimizing the ability to perform coherent change detection (CCD).

Abstract: An array of individual and autonomous modules are deployed in a region to be surveilled. Each module, contained in an air dropable bomblet, includes a GPS system for determining the exact location of the deployed module. The module also includes an rf receiver and transmitter, as well as an atomic clock circuit for providing highly precise time and clocking signals, with operation of the module circuitry being governed by a control computer. The computers of the modules are individually programmed such that the modules of the array collectively operate as a distributed phased array antenna system, but without any hardwired interconnection between the modules. In another embodiment a single receiver is utilized and the apparatus operates on the frequency set of the GPS system.

Abstract: A GPS radio navigation system utilizes an atomic clock in each user's GPS receiver station and a ground reference station located at a fixed, precisely known position which determines GPS time from satellite information and transmits an absolute time signal together with time-of-flight information over a communications path of precisely known length to the user stations, each at a fixed position. Once the atomic clock in a GPS receiver has been set to the precise GPS time, the user station is free to maneuver for an extended period of time during which its position is calculated from pseudorange and time information received from as few as three satellites and the time maintained by its atomic clock.

Abstract: Push-pull flux quantum gate array cells synchronously process a pair of polarized data signals. These polarized data signals can be derived from dual polarity data signals by separating the input signals into positive polarity data signals and negative polarity data signals. At least one logic or arithmetic operation is performed on each of the positive and negative polarity signals to produce modified positive and negative polarity signals respectively. These modified positive polarity and negative polarity signals can also be combined to produce a modified dual polarity output data signal. Numerous logic operations can be achieved in gate array cells which perform this signal processing method. By using push-pull flux quantum circuits, the need for auxiliary timing signals or interferometers is minimized.

Abstract: A digital set theoretic system is disclosed that expands the reasoning capability from reasoning with probability measures to reasoning with set theory measures and other Venn diagram type operations using linear transformations and power series transformations, and appropriate hardware and software implementations. This expansion also leads to an increase in precision of the output which can be provided by a hardwired power series expansion. A recursive power series expansion increases this precision while reducing the spatial requirements. The system also enhances flexibility by allowing the constants of the power series expansion to be selectable.

Abstract: The present system performs linear transformations on input probabilities and produces outputs which indicate the likelihood of one or more events. The transformation performed is a product of linear transforms such as P.sub.o =[A.sub.j P.sub.j +B.sub.j ].multidot.[A.sub.k P.sub.k +B.sub.k ] where P.sub.j and P.sub.k are input probabilities, P.sub.o is an output event probability and A.sub.j, B.sub.j, A.sub.k and B.sub.k are transformation constants. The system includes a basic processing unit or computational unit which performs a probabilistic gate operation to convert two input probability signals into one output probability signal where the output probability is equal to the product of linear transformations of the input probabilities. By appropriate selection of transformation constants logical and probabilistic gates performing the functions of AND, NAND, OR, NOR, XOR, NOT, IMPLIES and NOT IMPLIES can be created.

Abstract: A preprocessing device is disclosed which performs a linear transformation or power series expansion transformation on the input signals to a neural network node. The outputs of the preprocessing device are combined as a product of these linear transformations and compared to a threshold. This processing element configuration, combining a transformation with a product and threshold comparison, performs non-linear transformations between input data and output results. As a result, this processing element will, by itself, produce both linearly and non-linearly separable boolean logic functions. When this processing element is configured in a network, a two layer neural network can be created which will solve any arbitrary decision making function. This element can be configured in a probability based binary tree neural network which is validatable and verifiable in which the threshold comparison operation can be eliminated. The element can also be implemented in binary logic for ultra high speed.

Abstract: This application discloses a system that optimizes a neural network by generating all of the discrete weights for a given neural node by creating a normalized weight vector for each possible weight combination. The normalized vectors for each node define the weight space for that node. This complete set of weight vectors for each node is searched using a direct search method during the learning phase to optimize the network. The search evaluates a node cost function to determine a base point from which a pattern more within the weight space is made. Around the pattern mode point exploratory moves are made which are cost function evaluated. The pattern move is performed by eliminating from the search vectors with lower commonality.
