Abstract
An RF/digital signal-separating receiver is provided for GNSS and other RF signals. The receiver includes a first master antenna and a second slave antenna, which are positioned in spaced relation for directional, radio compass applications. First and second downconverters and first and second ADCs are located under the first and second antennas in analog signal areas, which configuration minimizes cross-coupling RF signals from the antennas and reduces noise. The first and second ADSs are connected to respective first and second correlators in a digital signal location, which is centrally located relative to the antennas. The correlators are connected to a microprocessor for computing distances for the received signals, from which the receiver's orientation or attitude is determined. A method of manufacturing receivers with this configuration is also disclosed.
