Do Septentrio receivers provide multi-path mitigation?
Septentrio receivers incorporate the patent pending code multi-path mitigation technique called APME (A Posteriori Multi-path Estimator). APME focuses primarily on short-delay multi-path, which is the most common multi-path type in practical circumstances. This is an important difference with other state-of-the-art multi-path mitigation techniques such as strobe correlator, which primarily suppress medium and long-delay multi-path. The result of the specific focus on short-delay multi-path is an improvement of up to 50% in multi-path reduction in practical circumstances. Moreover, APME is a bias-free multi-path mitigation technique, contrary to most other techniques, which introduce a satellite-dependent error in the code pseudo-range, which can cause extra measurement errors, notably in network applications.
