Preventing huge LEO satellite constellations from interfering with the geostationary earth orbit (GSO) satellite system, progressive pitch is a technique to avoid interference with the GSO satellite system that allows the LEO satellite system to maintain a certain angle of separation from the GSO satellite system. Aside from interference avoidance, there is also a need to ensure seamless coverage of the LEO constellation and to optimize the overall transmission capacity of the LEO satellite as much as possible, making it extremely complex to design an effective progressive pitch plan. This paper models an inline interference event and seamless coverage and builds an optimization problem by maximizing transmission capacity. This paper reformulates the problem and designs a genetic algorithm to solve it. From the simulation results, the strategy can avoid harmful interference to the GSO satellite system and ensure the seamless coverage of the LEO constellation, and the satellite transmission capacity is also maximized.<\/jats:p>","DOI":"10.3390\/s22166302","type":"journal-article","created":{"date-parts":[[2022,8,22]],"date-time":"2022-08-22T23:49:56Z","timestamp":1661212196000},"page":"6302","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Optimal Progressive Pitch for OneWeb Constellation with Seamless Coverage"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1584-7311","authenticated-orcid":false,"given":"Cheng","family":"Zou","sequence":"first","affiliation":[{"name":"Innovation Academy for Microsatellites of CAS, Shanghai 201203, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100049, China"},{"name":"School of Information Science and Technology, ShanghaiTech University, Shanghai 201210, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4759-0012","authenticated-orcid":false,"given":"Haiwang","family":"Wang","sequence":"additional","affiliation":[{"name":"Innovation Academy for Microsatellites of CAS, Shanghai 201203, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100049, China"},{"name":"School of Information Science and Technology, ShanghaiTech University, Shanghai 201210, China"}]},{"given":"Jiachao","family":"Chang","sequence":"additional","affiliation":[{"name":"Innovation Academy for Microsatellites of CAS, Shanghai 201203, China"},{"name":"Shanghai Yuanxin Satellite Technology Co., Ltd., Shanghai 201600, China"}]},{"given":"Fengwei","family":"Shao","sequence":"additional","affiliation":[{"name":"Innovation Academy for Microsatellites of CAS, Shanghai 201203, China"},{"name":"Shanghai Yuanxin Satellite Technology Co., Ltd., Shanghai 201600, China"}]},{"given":"Lin","family":"Shang","sequence":"additional","affiliation":[{"name":"Innovation Academy for Microsatellites of CAS, Shanghai 201203, China"},{"name":"Shanghai Yuanxin Satellite Technology Co., Ltd., Shanghai 201600, China"}]},{"given":"Guotong","family":"Li","sequence":"additional","affiliation":[{"name":"Innovation Academy for Microsatellites of CAS, Shanghai 201203, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100049, China"},{"name":"School of Information Science and Technology, ShanghaiTech University, Shanghai 201210, China"},{"name":"Shanghai Yuanxin Satellite Technology Co., Ltd., Shanghai 201600, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,22]]},"reference":[{"key":"ref_1","unstructured":"Handforth, C.
