This could be effected by a second, on-orbit manoeuvre during the first southern Polar pass, where the orbital planes cross. This would align the RAAN, moving the satellite into the plane of FIA Radar 1. I think this is what might have happened with the FIA Radar 3 launch (http://www.satobs.org/seesat/Dec-2013/0042.html). This still begs the question why they would not launch directly into a 123 deg inclination anyway, as with all previous FIA launches. - Marco ----- Dr Marco Langbroek - SatTrackCam Leiden, the Netherlands. e-mail: sattrackcam_at_langbroek.org Cospar 4353 (Leiden): 52.15412 N, 4.49081 E (WGS84), +0 m ASL Cospar 4355 (Cronesteyn): 52.13878 N, 4.49937 E (WGS84), -2 m ASL Station (b)log: http://sattrackcam.blogspot.com Twitter: _at_Marco_Langbroek ----- _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-lReceived on Wed Jan 10 2018 - 10:05:19 UTC
