By efficient and secure, we mean maintaining a cryptographic security strength requirement with minimum data bandwidth and watermark signal degradation. We exploit many strategies, including using Timed-Efficient Stream Loss-tolerant Authentication (“TESLA”), sectioned parallelized cryptographic secret distribution, and only one constant, independent spreading code watermark degradation. Our design allows multi-cadence (i.e., slow and fast) distribution even with only a single watermark degradation. Our design maintains standard 128-bit security with a single minimum bandwidth channel while allowing for authentication of many GNSS services.","PeriodicalId":262695,"journal":{"name":"The International Technical Meeting of the The Institute of Navigation","volume":"14 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":"125328348","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}

Radio-Frequency Pulsar Observation using Small-Aperture Antennas 利用小口径天线进行射频脉冲星观测

{"title":"Radio-Frequency Pulsar Observation using Small-Aperture Antennas","authors":"Ryan McKnight, F. van Graas","doi":"10.33012/2022.18259","DOIUrl":"https://doi.org/10.33012/2022.18259","url":null,"abstract":"Recent research on pulsar based navigation and timing by organizations such as NASA and ESA has primarily focused on X-ray measurements as opposed to previous research which instead focused primarily on radio-frequency (RF) measurements. X-ray based systems offer the potential for greater accuracy than RF based systems and do not require the large antenna apertures historically considered to be necessary for adequate performance of an RF system. However, recent RF studies have suggested the feasibility of 1-10 microsecond timing performance using an antenna with an effective aperture on the order of 10 square meters, which is more optimistic than many previous results. This level of performance may be sufficient to prove useful for both terrestrial and space applications, particularly in deep space or even cislunar space where navigation and timing performance requirements are typically more relaxed. Such a radio-frequency based solution would not require the large, heavy, complex hardware required to receive X-ray signals and could be particularly advantageous for small spacecraft where size, weight, and cost are of higher concern. This paper serves as a literature review of radio-frequency pulsar observation, timing, and navigation systems. It examines the theoretical relationship of system parameters such as antenna size, amplifier noise figure, observation time, and processing techniques to overall system signal-to-noise ratio (SNR) and measurement performance. It then details the design of a terrestrial experiment to observe pulsars in the radio-frequency band using two small-aperture observing stations and low-cost hardware with the goal of determining experimentally the minimum practical antenna size for radio-frequency pulsar measurements as a function of signal-to-noise ratio, measurement performance, and observation time. Additionally, experimental results of pulsar observations performed by amateur radio operators are discussed and used to provide context to the theoretical results.","PeriodicalId":262695,"journal":{"name":"The International Technical Meeting of the The Institute of Navigation","volume":"5 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":"131440970","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}
