I ad my congratulations! Based on the hybrid optical-radio orbit that Scott tweeted a few hours ago (https://twitter.com/coastal8049/status/1386956328636096515?s=20), it appears that the NROL-82 payload (USA 314) has been placed in virtually the same orbital plane as USA 224 (which it is likely intended to replace). RAAN differs by ~1 degree, inclination by ~0.1 degree The orbital altitude is (for now) somewhat different, but it might manoeuvre to make those match later. So let us continue to keep an eye on it. As the orbit is very preliminary, the figures above are rule of thumb figures. - Marco ----- Dr Marco Langbroek - SatTrackCam Leiden, the Netherlands. e-mail: sattrackcam_at_langbroek.org launchtower: http://launchtower.langbroek.org Station (b)log: http://sattrackcam.blogspot.com Twitter: _at_Marco_Langbroek ----- _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-lReceived on Tue Apr 27 2021 - 06:09:11 UTC
