Subject:[SLR-Mail] No.2505: Succesfull Grace Follow On 1 and 2 pass from Potsdam station

Dear ILRS colleagues,

we just had our
first succesfull Grace
Follow On Pass (24th of May 2018 @ 22:17 UTC) and even received returns from both satellites as they were passing over Potsdam station. As the GPS
receivers are
now switched on, the predicitions are already quite accurate, even so shortly after the launch. So the timebiases were very small and
around

-0.3 ms for GFO1

and

+0.5 ms for GFO2.

Since the orbit quality is so good already, laser tracking shoud be feasible
now. Good luck with that!

Best

Sven Bauer
