dc.description.abstractWithin civil aviation the implementation of Performance Based Navigation (PBN) and Automatic Dependent Surveillance Broadcast (ADS-B) is ongoing on a worldwide level. It is of particular interest to assess the quality of these new applications. For instance, within PBN, the Total System Error (TSE) is a safety relevant parameter, especially for applications in demanding environments such as approach procedures within mountainous areas. One solution, in order to estimate the TSE, would be to equip an airplane with a dedicated reference GPS receiver and derive carrier-phase position solutions. This approach would be feasible for flight trials but it is barely impossible to apply for commercial operations, e.g. for monitoring purposes of a complete traffic situation. The setting is analogous for the quality assessment of ADS-B, where the TSE cannot be derived by the data broadcast, but has to be retrieved on-board through dedicated non-operational equipment. Therefore a solution is envisaged by applying multilateration (MLAT) technology operating at 1090 MHz. This method has the advantage that all airplanes operating under Instrument Flight Rules (IFR) can be tracked through their transponder replies. Based on the envisaged solution the Zurich University of Applied Sciences in Winterthur, Switzerland, has developed a mobile MLAT system for skyguide. The advantage of this system compared to classical MLAT is the fact, that it can be quickly installed and operates autonomously during 48h powered only by a battery. Therefore no specific infrastructure is needed for the operation of the system. Dedicated flight trials with airplanes equipped with Mode-S transponders and ADS-B transmitters have been performed in order to assess the position accuracy of the mobile MLAT. Additionally, independent GNSS receivers were installed on-board these airplanes too which allowed the determination of the airplane positions through carrier-phase solution in order to validate the mobile MLAT accuracy performance. The measured accuracy within the area of interest is in the range of 5 to 10 m (1σ) depending on the geometry of the receivers.de_CH
