Title: | Nominal range error analysis of BDS for ARAIM | Authors: | Zhang, H Jiang, Y |
Issue Date: | 2021 | Source: | In proceedings of the 2021 International Technical Meeting of The Institute of Navigation, January 25-28 , 2021, p. 201-211 | Abstract: | The Advanced Receiver Autonomous Integrity Monitoring (ARAIM) requires a minimum performance level of the satellite constellation that is used for aircraft navigation. The distribution of the satellite Signal-In-Space (SIS) range error needs to be sufficiently characterized considering the correlation in error terms. The nominal range error for 14 BDS-2 and 11 BDS-3 satellites and the correlation of orbit and clock errors are analyzed based on one-year data of broadcast and precise ephemerides. Results show significant differences in the nominal range error performance among three different types of satellites of GEO, IGSO and MEO and different manufacturers. The service history is broken down into monthly dataset to analyze the variation of single satellite performance and BDS-2 is compared with BDS-3 from multiple aspects. The URE is characterized and one-sigma value is 9.4m, 5.8m and 4.9m for GEO, IGSO and MEO, respectively. Based on the correlation analysis, orbit error components show significant disparity in the harmonic period between satellite types. Like orbit error components, the large difference also exists in clock error regarding convergence time. Independent sampling interval is estimated with the time interval ranging from 44 to 67, 14 to 15 and 11 to 12 hours for GEO, IGSO and MEO, respectively. | Publisher: | Institute of Navigation | ISBN: | 978-0-936406-27-5 | DOI: | 10.33012/2021.17813 | Description: | 2021 International Technical Meeting of The Institute of Navigation, January 25 - 28, 2021, online | Rights: | Posted with permission of the author.
