Immediately after the injection of the satellite, the two solar panels were deployed. The three Imaging Cameras have been oriented towards Earth. All operations and health checks required prior to switching on the three Imaging Cameras have been satisfactorily completed. Orbital trimming manoeuvre was conducted successfully on April 22, 2011, and RESOURCESAT-2 is now placed in the final orbital configuration in a sun-synchronous polar orbit with perigee of 813 km; apogee of 825 km and inclination of 98.78 degree. Operation of the Imaging cameras is scheduled to commence on April 28, 2011. The first imaging pass on April 28th is expected to cover about 3000 km stretch of Indian landmass from JOSHIMUT (in Uttarakhand) to KANNUR (in Kerala).
Pradeep - you're right that I am being speculative here. But it is informed speculation. I would bet money that I'm right. If it turns out there is another reason (I haven't thought of a plausible one) I'll certainly print a retraction. - Jonathan
Pradeep - you should have taken the bet! I was wrong. I was wrong, wrong, wrong. As you pointed out to me on facebook, TLEs have now belatedly become available. I hereby retract. Egg, face, me, all over. - Jonathan
Official TLEs of Resourcesat 2 finally began to be released today (Apr 25 UTC), on Space Track. So far, only two TLEsets have appeared, and it is too soon to judge whether this is a permanent change of policy.
It is certainly very strange that all of the objects from this launch had Two-Line Orbital Elements issued by USSSN immediately after the launch, but it took so long for data for the main satellite to appear.I am sure that there is an innocent explanation but I cannot immediately think of it, other than some dumb bureaucratic error within USSSN.
Well, note that between the first set of elements for A (actually issued in error under the D object's number) and the new set, there was an orbit maneuver.So my alternate theory is that it did an orbit adjust while they were still trying to figure out which object was which, and they lost the damn thing for a few days. Not very impressive if true.

Not very impressive if true. They seem to have changed all of the designations on April 21. RESOURCESAT-2 was initially labelled D and then changed to A. YOUTHSAT was the original A became B. XSat which was B became C. And the rocket body which was C became D. So, now:2011-015A - RESOURCESAT-22011-015B - YOUTHSAT2011-015C - XSat2011-015D - rocket bodyNo idea on why this was done. -Pradeep
There was a Critical conjunction between Resourcesat-2 and another active satellite MetopC owned by Eumetsat on 7 June 2023. ISRO coordinated with both MetopC team and NASA’s CARA team regarding this conjunction. Resourcesat-2 has undergone regular ground track maintenance manoeuvre and the conjunction is mitigated.
