Abstract

A correlator and method of correlation for Global Navigation Satellite Systems (GNSS) are disclosed in which a multi-navigation pseudorandom operation is performed on an input satellite signal to provide a correlated output. The input satellite signal is input to an N parallel channel correlator (102). Each parallel channel (301) contains a dynamically allocating multi-resolution control block that controls carrier (404) and code (405) oscillator output frequency and resolution separately in each channel. Each channel may also include a multi-system GNSS pseudo- random block (502), low-power computation blocks and low-power control mechanism.
