RETRACTION NOTICE TO “CORRECTED GYROCOMPASS SYNTHESIS AS A SYSTEM WITH CHANGEABLE STRUCTURE FOR AVIATION GRAVIMETRIC SYSTEM WITH PIEZOELECTRIC GRAVIMETER” [AVIATION 18(3), 134–140, 2014]

The following article is being retracted from publication in Aviation Journal: Corrected gyrocompass synthesis as a system with changeable structure for aviation gravimetric system with piezoelectric gravimeter, by Elena Nikolaevna Bezvesilnaya and Andriy Hennadiiovych Tkachuk, Volume 18, Issue 3, 2014, pp. 134–140, Aviation, https://doi.org/10.3846/16487788.2014.969878 https://journals.vilniustech.lt/index.php/Aviation/article/view/2941 Received 20 November 2013; published online 02 October 2014, since the same results are published in Deutsche Gesellschaft für Ortung und Navigation article Corrected Gyrocompass Synthesis as a System with Changeable Structure, by Bezvesilnaya O. N., Ivanov S. V., Ryzhkov L. M. and Staritskiy L. P., Proceeding of Symposium Gyro Technology 2003, Stuttgart, Germany, 2003, 12.0–12.8 (ISSN 1439-4502). The Editors and publishers of the journal, Vilnius Gediminas Technical University, note that we received, peer-reviewed, accepted and published the article on the basis that the authors are presenting original results and are not intending to publish them in any other journal. The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as “retracted”.
