A sensor fusion of multiple complementary sensors (e.g. Global Navigation Satellite System (GNSS) receivers, inertial sensors, odometry, camera, Lidar, Ultra-Wide Band) is typically performed to achieve the objectives of both high precision and high reliability. A sensor fusion relies on an accurate knowledge of the measurement statistics. For static GNSS receivers, this assumption is typically well justified as multipath errors are only slowly changing with time. Henkel and Sperl (2016) and Henkel et al. (2016) showed that pseudorange multipath errors can be estimated as additional","PeriodicalId":261056,"journal":{"name":"Proceedings of the 2023 International Technical Meeting of The Institute of Navigation","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122970511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The combination of hardware and software enables us to simulate the RFI and GNSS environment on the aircraft in the laboratory. Considering existing different jamming types and power level effect on the GNSS integrity, several jamming type data sets are pre-generated and jamming power is adjustable by setting the transmitter gain. The receivers collect the raw measurements needed for protection level computation or output built-in protection level. The algorithm to compute the protection level is the multiple hypothesis solution separation algorithm (MHSS). Then, convert the protection level to Navigation Integrity Category (NIC) which is a field in Automatic Dependent Surveillance-Broadcast (ADS-B). Three receivers from surveying to consumer grade are tested for examining different responses of receiver brands.","PeriodicalId":261056,"journal":{"name":"Proceedings of the 2023 International Technical Meeting of The Institute of Navigation","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124997999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
