1971-117A
A US-A satellite was launched in Dec 1971 from Baikonur,reached orbit and was named Kosmos-469. It operated in the low orbit for ten days before the reactor section was separated and boosted to a higher orbit. One solution for the orbit change is with burns at 0637, 0729 UTC on Jan 4; this is consistent with the claimed time of orbit change in the RAE tables. However, a pair of elsets for the separate reactor and propulsion sections for epoch around 0300 UTC suggests that separation took place before that time. I therefore adopt another solution with burns at 2013 and 2105 UTC on Jan 3.
