Correspondence A. Hauschild, German Aerospace Center (DLR), German Space Operations Center (GSOC), Weßling, Germany. Email: andre.hauschild@dlr.de Abstract The paper presents attitude determination results of the “GPS Attitude, Positioning and Profiling Experiment” (GAP) on board the CASSIOPE satellite using real flight data. The GAP payload consists of five minimally modified commercial-off-the-shelf NovAtel OEM4-G2L receivers that provide dualfrequency GPS measurements and allow for attitude and orbit determination of the satellite as well as electron density profiling. To the authors' knowledge, the CASSIOPE mission is the first space mission that provides dual-frequency observations for attitude determination. The data has been analyzed with a GPS attitude determination algorithm originally developed for the analysis of data from the “Flying Laptop” mission. The GPS-based solution for selected attitude maneuvers is compared to a reference orientation provided by the satellite's star sensors. Furthermore, an analysis of the typical time-to-first-fix (TTFF) for the attitude solution is provided. The advantage of dual-frequency ambiguity fixing compared to single-frequency is assessed.

The general method of evaluating the ground subsystem integrity risk consists of placing a series of monitors on the ground. However, only when the appropriate threshold is applied can the risk be accurately evaluated. For BDS GBAS, there is currently no developed method for threshold modeling. This paper proposes an improved method for threshold modeling of the BDS GBAS ground monitor based on real data collected at Dongying Airport. Compared with the original approach, this method results in certain improvements. The improvements are as follows: (1) Definition of the boundaries of the core and tails is proposed to verify satisfaction of the overbounding requirement in the inflation step to calculate thresholds. (2) This paper uses time instead of elevation for statistics that are independent of elevation in the normalization of test statistics. (3) The method of truncation is used in this paper to mitigate the heavy-tailed distribution that is encountered in the calculation of the data distribution. (4) The proposed method relies on the t distribution instead of the Gaussian distribution when dealing with the analysis of a small sample. Finally, combined with measured data and the proposed improved method mentioned, certain typical threshold models are developed and analyzed for different cases, including different constellations (GPS and BDS), frequencies and satellite orbits.
