Abstract

GNSS receiver includes first type correlators and a maximum selecting unit selecting an output from the first type correlators, and with a common control of all the correlators in code delay, carrier phase and carrier frequency; second type correlators with individual control in code delay of each correlator or each sub-group of second type correlators and with common control of all second type correlators in carrier phase and frequency; and a processor. The first type correlators can convolve one quadrature only, and demodulates CSK symbols, the second type correlators calculate discriminator values for CSK-modulated signal DLL, the demodulated data then is used by the processor to produce improved position and velocity.
