> Analysis of 6 S-band Doppler curves obtained during the first 24h since launch yield the following orbital elements, determined solely from the radio observations. If I may be permitted a non-substantive comment -- please do not post replies -- I find it curious that NRO satellites, the orbits of which are kept secret for reasons of national security, carry S-band beacons that enable their orbits to be determined by methods used to track Sputnik 1 in 1957. _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-lReceived on Tue Apr 27 2021 - 16:12:46 UTC
