Delta IV launch put GPS II F3 satellite in correct orbit but only after compensating for low thrust

by | Oct 9, 2012 | commercial launch services, Satellites | 0 comments

A Delta IVM+ 4,2 launch was reported as placing the GPS II F3 satellite into the correct orbit for the US Air Force on 4 October .  However, it has later been announced that the launch vehicle’s second stage RL-10 engine had a lower than expected thrust which had to be compensated during the three burn sequence.  An investigation is now taking place into the cause of the launch anomaly.
