A receiver, and associated process, for tracking a GNSS positioning signal comprising a carrier modulated by a subcarrier and a spreading code, the receiver comprising:
- at least one tracking loop configured to calculate a first pseudo range from said GNSS positioning signal,
- a first discrimination circuit (521) configured to calculate an ambiguous discriminator value from the subcarrier and the spreading code of said GNSS positioning signal,
- a calculation circuit (522) configured to calculate a value representative of a tracking error of said tracking loop,
- a second discrimination circuit (530) configured to select one of said ambiguous discriminator value and said value calculated by the calculation circuit, and to generate a first non-ambiguous discriminator value, an amplitude of which is based on an amplitude of the selected value, and a sign of which is a sign of said value calculated by the calculation circuit. |
