The cycle-slip detection reliability can be significantly improved with three-frequency signals. Indeed, on one hand the Extra-wide-lane combination provides a several meters wavelength that dramatically improves the sensibility of this code-based detector, overcoming most of the problems mentioned in the article Detector based in code and carrier phase data: The Melbourne-Wübbena combination. On the other hand, two independent geometry free combinations are possible to generate, which allow to relay the detection in carrier-phase data detectors as those described in article Detector based in carrier phase data: The geometry-free combination

Thence, a simple scheme can based in the following elements: (1) Two carrier-phase based detectors for two independent geometry free combinations. (2) A Melbourne-Wübbena detector using the extra-wide-lane combination.
