Tracking Diary

This log covers the first four months of life in orbit for the two STSS Demonstrator satellites.

Entries are written from the point of view of tracking the two satellites and, in particular, measuring the separation distance as the mission went through a test phase where they drew apart and then drifted back together before stabilising the operational separation.
