1.   Because they are closer, LEO satellites need a smaller antenna, roughly the size of a ballpoint pen.

2.   A smaller antenna is handling the data transmissions, though at a much slower rate.

3.   But data compressed and saved on the recorder could be played back later for slower transmissions through a smaller antenna.

4.   So communication with Galileo is through a smaller antenna at a much slower rate.

5.   Smaller antenna can be and have been mounted on smaller vehicles.

6.   The eight smaller antennas stand out like communion wafers.
