GNSS dataless signal tracking with a delay semi-open loop and a phase open loop

► We propose a Delay Semi Open Loop for the tracking of the code of a GNSS signal. ► We propose a Bayesian change point detector for this code tracking loop. ► We propose a Phase Open Loop for the tracking of the phase of a GNSS signal. ► We propose a Bayesian circular filter for this phase tracking loop. ► The proposed methods are assessed on synthetic and real data.
