Abstract
A GPS receiver includes a satellite receiver/processor having an input that receives input signals from at least one GPS satellite. The output of the receiver/processor provides satellite-related navigation information. A neural network receives the satellite-related information to obtain an output signal representative of receiver-related navigation information. The neural network includes a first node layer connected to a second node layer through a first connection layer and a third node layer connected to the second node layer through a second connection layer. Each of the node layers comprises a plurality of neurons.
Claims9
A navigation system for tracking the position of an object within a geographic area, said system comprising:
- a satellite receiver/processor having an input receiving input signals from at least one GPS satellite and an output providing satellite-related navigation information and a neural network having an input receiving the satellite-related information to obtain an output signal representative of receiver-related navigation information;
- and
- at least one complimentary device for making use of the receiver-related navigation information;
- wherein the neural network comprises one of either a discrete-time Hopfield neural network, a continuous-time Hopfield neural network, a cellular neural network, a multilayer perception networks, a self-organizing system, a radial basis function network or a high-order neural network.
A navigation system for tracking the position of an object within a geographic area, said system comprising:
