Two test star trackers- have been mounted on the Space Technology Experiment and Climate Exploration (STECE) satellite, a small satellite mission developed by China. To extract and compensate the LFE of the attitude measurements for the two test star trackers, a new approach, called Fourier analysis, combined with the Vondrak filter method (FAVF) is proposed in this paper. Firstly, the LFE of the two test star trackers\u2019 attitude measurements are analyzed and extracted by the FAVF method. The remarkable orbital reproducibility features are found in both of the two test star trackers\u2019 attitude measurements. Then, by using the reproducibility feature of the LFE, the two star trackers\u2019 LFE patterns are estimated effectively. Finally, based on the actual LFE pattern results, this paper presents a new LFE compensation strategy. The validity and effectiveness of the proposed LFE compensation algorithm is demonstrated by the significant improvement in the consistency between the two test star trackers. The root mean square (RMS) of the relative Euler angle residuals are reduced from [27.95\u2032\u2032, 25.14\u2032\u2032, 82.43\u2032\u2032], 3\u03c3 to [16.12\u2032\u2032, 15.89\u2032\u2032, 53.27\u2032\u2032], 3\u03c3.<\/jats:p>","DOI":"10.3390\/s16101669","type":"journal-article","created":{"date-parts":[[2016,10,12]],"date-time":"2016-10-12T10:18:49Z","timestamp":1476267529000},"page":"1669","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Low-Frequency Error Extraction and Compensation for Attitude Measurements from STECE Star Tracker"],"prefix":"10.3390","volume":"16","author":[{"given":"Yuwang","family":"Lai","sequence":"first","affiliation":[{"name":"Xichang Satellite Launch Center, Xichang 615000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Defeng","family":"Gu","sequence":"additional","affiliation":[{"name":"School of Science, National University of Defense Technology, Changsha 410073, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junhong","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Science, National University of Defense Technology, Changsha 410073, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenping","family":"Li","sequence":"additional","affiliation":[{"name":"Beijing Institute of Tracking and Telecommunication Technology, Beijing 100094, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dongyun","family":"Yi","sequence":"additional","affiliation":[{"name":"School of Science, National University of Defense Technology, Changsha 410073, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2016,10,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"34","DOI":"10.1117\/12.579051","article-title":"Precision attitude and position determination for the Advanced Land Observing Satellite (ALOS)","volume":"5659","author":"Iwata","year":"2005","journal-title":"Proc.
