Maybe there was a secondary thruster somewhere to provide some separation.<p>I went back and recorded the release speed (km&#x2F;hr), altitude (km) for each drop:<p>25960 626<p>25954 627<p>25950 628<p>25944 630<p>25937 632<p>25935 632<p>A circular orbit at that height is about 29000 km around; 25 km&#x2F;hour of difference between release 1 and 6 would give them a separation of 6 degrees longitude&#x2F;day, or ~50 days until the faster satellites &#x27;lap&#x27; the slowest one.<p>Not any sort of rocket scientist, but I gather the strategy with these kind of LEO satellites is to just throw a pile of them up there semi-randomly, and count on at least one being in the neighborhood when you want to talk to it.<p>edit: 
Last paragraph is wrong. See my comment two levels down for the answer.
