  • Radionavigation signal tracking device
    Patent number: 9529070
    Abstract: A radionavigation signal tracking device comprises a first and a second tracking stage for radionavigation signals. The first tracking stage comprises a first carrier phase-locked loop. The latter produces a first error signal arising from a phase difference between the first carrier and its replica. The phase of the replica of the first carrier is adjusted with the first error signal. The second tracking stage comprises a second carrier phase-locked loop. The latter produces a second error signal arising from a difference between the first phase difference and a phase difference between the second carrier and the replica thereof. The phase of the replica of the second carrier is adjusted with the first and second error signals.
