15 September 2016 Bjarne: You still do not understand the ISS and Galileo 5 and 6 testsYou don't understand , it ...

- The upcoming Atomic Clock Ensemble in Space (the ISS test) is a test of General Relativity
The Wikipedia article is outdated - launch in August 2017, not 2016: ISS Utilization: ACES (Atomic Clock Ensemble in Space) / PHARAO
Launch: A launch of the ACES/PHARAO platform aboard a Dragon capsule of SpaceX (CRS-13) is scheduled for August 2017.
Orbit: Near-circular orbit of the ISS, mean altitude of ~400 km, inclination of 51.6º, period of ~ 90 minutes.
The planned duration of the mission is 18-36 months. First 6 months are reserved for functionality verification of instruments and performances evaluation. The first objectives are to study the performances of this first cold atom space clock and reach frequency accuracy lower than 3 x 10-16 (with a final goal at 10-16) and deliver a timescale with 25 ps/day stability. The microwave link will have to demonstrate the capability to perform phase comparisons between space and ground clocks with a resolution at the level of 0.3 ps over one ISS pass (300 s), 7 ps over 1 day, and 23 ps over 10 days. - The ongoing Galileo 5 and 6 test is a test of General Relativity. It does not measure any acceleration - not even "perigee acceleration".
