Abstract: A portable reconfigurable geolocation system is provided. The system includes a portable user node and one or more portable pseudolite nodes in communication one another and with the user node. Each of the user nodes and pseudolite nodes includes a transmitter that generates a signal on one or more carrier frequencies. Each signal is modulated with digital signals necessary to establish distances between the nodes and to convey data between the nodes. Each node also includes a receiver for receiving and demodulating the signals transmitted between the nodes, and a processor for receiving the demodulated signals, extracting data values and derived values from the demodulated signals and determining a three-dimensional position of each node in the system.

Abstract: An adaptive attenuator is provided, the adaptive attenuator including at least two sensor ports. Each of the sensor ports receives an input signal that includes data on a first channel and a reference sequence on a second channel. One or more delay ports is coupled to each sensor port for receiving the input signal, and a computational port is coupled to the sensor ports and the delay ports. The computational port receives the input signal and the output of the delay ports and performs one or more computations to produce a processed signal which is substantially free of interference. A phase restorer receives the processed signal and the reference sequence and restores phase to the processed signal in accordance with the reference sequence.
