MULTICHANNEL CORRELATOR AND NAVIGATION RECEIVER Russian patent published in 2010 - IPC G01S5/14 

FIELD: physics, navigation.

SUBSTANCE: invention relates to devices for determining position through determination in one coordinate system, absolute distances to several spaced out points with known position using satellite radio navigation system (SRNS) signals. The multichannel correlator has at least sixteen universal channels for receiving navigation signals, two independent units for fast detection of navigation signals and a second mark generator. The navigation receiver has a multichannel correlator with two independent fast detection units and universal channels, a low-noise amplifier, three band-pass filters, a mixer and an amplifier with differential outputs, two quadrature demodulators, two ADCs, a reference generator, two frequency synthesisers, a navigation signal processor, a multichannel correlator and reprogrammable read-only memory.

EFFECT: increased accuracy of position finding.
