Web1 jan. 2024 · For these data, we adopt the ionosphere-free (IF) combination to detect cycle slips. The IF combination can reduce the impact of the ionosphere by nearly 99%, thereby providing a detection value precise enough to detect the cycle slips with the magnitude of one or two cycles. However, the IF combination has two main drawbacks. WebThe integer nature of the ionosphere-free ambiguities is confirmed. The amplification of the wavelength of a second combination is discussed, along with the so-called ‘odd/even’ relationship and its impact on Teunissen ’s [1995] hypothesis of the incompatibility of certain double combinations.
WebIonosphere Scintillation Service (ISM) ISM provides global nowcast S4 and σ Φ maps based on numerous GNSS receivers (1 Hz) and a few high rate GNSS receivers (50 Hz). Furthermore, it provides forecast of S4 and σ Φ maps up to 6 hours ahead. The forecasts are most reliant near the equator and less reliant in polar regions. WebIf, on one hand, the ionosphere slant delay is available and the wide-lane bias is known, the ionosphere-free bias , can be computed and used by a navigation filter. Since that estimate is more accurate than the one obtained from processing the ionosphere-free measurements, it helps to accelerate filter convergence in the classical PPP model.
