Information regarding common flight states, such as position, ground speed, and the vertical rate is broadcast by ADS-B and has already been decoded and made available for researchers via the OpenSky historical database. However, there is still a large amount of Mode S communication data that has not yet been fully explored. Specifically, the information contained in Enhanced Mode S Surveillance downlink messages can be utilized to better support ATM research. The challenge of decoding such information lies in the implicit inference process for Mode S Comm-B messages. This paper presents a new open library, pymodes-opensky, which connects the existing open-source pyModeS decoder to the raw Mode S messages from the OpenSky historical database through the Impala shell. It also presents a convenient workflow that can be used to obtain additional information regarding airspeeds, flight intentions, and meteorological conditions of a given flight from the OpenSky database. An analysis based on a global dataset from OpenSky is conducted, and the associated Mode S interrogation statistics in different regions are shown.<\/jats:p>","DOI":"10.29007\/mmsb","type":"proceedings-article","created":{"date-parts":[[2019,12,23]],"date-time":"2019-12-23T18:10:42Z","timestamp":1577124642000},"page":"63-52","source":"Crossref","is-referenced-by-count":3,"title":["Integrating pyModeS and OpenSky Historical Database"],"prefix":"10.29007","volume":"67","author":[{"given":"Junzi","family":"Sun","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jacco","family":"Hoekstra","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"11545","event":{"name":"Proceedings of the 7th OpenSky Workshop 2019"},"container-title":["EPiC Series in Computing"],"original-title":[],"deposited":{"date-parts":[[2019,12,23]],"date-time":"2019-12-23T18:10:43Z","timestamp":1577124643000},"score":1,"resource":{"primary":{"URL":"https:\/\/easychair.org\/publications\/paper\/f7Wc"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[null]]},"references-count":0,"URL":"https:\/\/doi.org\/10.29007\/mmsb","relation":{},"ISSN":["2398-7340"],"issn-type":[{"type":"print","value":"2398-7340"}],"subject":[]}}
