   You claim you can read, so read the paper:   
      
   >> https://paulba.no/paper/Initial_results_of_GPS_satellite_1977.pdf   
      
   The title is:   
     INITIAL RESULTS OF THE NAVSTAR GPS NTS-2 SATELLITE   
      
   The authors didn't care if Einstein was right or wrong, they   
   did what they had to do to make the first GPS satellite work.   
      
   Abstract:   
   "NTS-2 was successfully launched on 23 June 1977   
     into a near 12- hour circular orbit. Precise frequency   
     and timing signals are derived from the two cesium   
     frequency standards. This paper discusses the launch   
     and preliminary results which include verification of   
     the relativistic clock effect."   
      
   The test was done by u.S.Naval Research Laboratory.   
   They weren't sure if Einstein was right, that's why   
   the satellite clock initially was running at its proper   
   rate as defined by SI.   
      
   The rate of the clock in the satellite was during 6 days measured   
   to be (1 + 4.425e-10) faster than the clock on the ground.   
   See fig. 20.   
      
   That's 19.064 μs more per orbit than the clock on the ground.   
   This is slightly less than the 19.235 μs predicted by GR,   
   but it is as can be expected by the precision of the atomic clock   
   in the satellite, which was in the order of 1e-12.   
      
   But their job was to make the GPS work, so after it was confirmed   
   that Einstein was right, they switched on the frequency synthesiser   
   which adjusted the frequency down by the factor (1 - 4.45e-10).   
   (Later the factor was changed to (1 - 4.4647e-10).   
      
   --------------------   
      
   You will of course claim that all this is a lie,   
   Einstein was wrong, so the unadjusted clock measured   
   the same duration of an orbit as did the clock on the ground,   
   so no adjustment of the rate of GPS clocks is done.   
      
   You claim that the GPS satellite clocks are adjusted down   
   by the factor (1 - 4.4647e-10).   
      
   So you have a problem, Maciej.   
   Either Einstein was wrong, and you lied when you said   
   that the clocks were adjusted down,   
   or Einstein was right, and you were right when you said   
   that the clocks were adjusted down.
