To implement existing [1,3] vector delay lock loop algorithms (VDLLA) for processing navigation signals in the receiver of global navigation satellite system (GNSS), a high-performance processor is required. This is because the main computations to be carried out at the rate of correlation integrals (50...100 Hz) formation.

The paper shows that by increasing error of navigation parameters in noncoherent receiver of GNSS signals, it is possible to reduce the requirements for the rate of computations (up to 1…10 Hz) for the implementation of VDLLA. Reducing the computation rate leads to decrease in the computational volume and decrease requirements to receiver processor. Proposes a method for initializing VDLLA. Provides an estimate receivers noise immunity gain in comparison with two-stage receiver.
