Phelts, Todd Walter, Rhiannon Sanchez","doi":"10.33012/2022.18257","DOIUrl":"https://doi.org/10.33012/2022.18257","url":null,"abstract":"Approximately 10 years of continuous WAAS signal quality monitoring (SQM) measurements have been collected. Numerous changes to the GPS satellite constellation, WAAS ground system, and user receiver configurations have occurred during that time. A number of anomalous signal deformation events have also been cataloged on L1 since 2009. Despite these various changes, WAAS SQM data can be used to assess the stability and evolution of nominal signal deformations of the L1 C/A code signals from the GPS satellites. In addition, the more recent availability of L5 SQM data and the addition of GPS Block III SVs allows comparisons to the original L1 algorithm and predictions for future nominal L5 characteristics. It is shown that WAAS SQM measurements remain sensitive to changes in nominal signal deformations. Also, while the limits of nominal deformations appear quite stable and signal anomalies tend to be rare, unexpected events can and do occur. Finally, though GPS Block III SVs have dissimilar signal characteristics to previous block types, the maximum nominal range biases on L1 continue to be well-bounded by the threat model and minimum range error limits required to guarantee integrity for single-frequency WAAS aviation users. It is anticipated this will hold true for future dual-frequency WAAS users as well.","PeriodicalId":262695,"journal":{"name":"The International Technical Meeting of the The Institute of Navigation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124238141","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}

LuGRE was chosen by the NASA Commercial Lunar Payload Services (CLPS) program as one of ten payloads on its “19D” task order for delivery to the lunar surface in 2023. The LuGRE payload consists of a weak-signal GNSS receiver, a high-gain L-band patch antenna, a low-noise amplifier, and an RF filter. The receiver will track GPS L1 C/A and L5, and Galileo E1 and E5a signals and will return pseudorange, carrier phase, and Doppler measurements to the ground. It will also calculate least-squares point solutions and Kalman-filter based navigation solutions onboard. In addition, the receiver features the capability to record raw I/Q baseband samples for downlink and ground processing. way for use by future lunar Gateway, robotic and human landers, and rovers. This paper provides a detailed overview of the LuGRE payload, including its design, concept of operations, and its predicted ability to meet its core science objectives. The baseline science investigations and priorities are outlined. Simulated performance results are shown based on the latest calibrated models including signal strength, signal availability, onboard navigation performance and convergence properties, and ground-based post-processed navigation performance.","PeriodicalId":262695,"journal":{"name":"The International Technical Meeting of the The Institute of Navigation","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131324257","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}
