Mission details:

• On Apr 25, 2016 Arianespace flight VS14 launched a Soyuz ST-A from the ELS pad at CSG Sinnamary. The Fregat stage first burn reached an initial orbit of 695 x 700 km and deployed the Sentinel-1B radar imaging satellite for ESA.
  It then made a burn to 442 x 690 km and deployed three 1U cubesats: OUFTI-1 for the University of Liege, AAUSAT-4 for Aalborg University in Denmark, and E-St@r-II for the Politecnico di Torino.
  The ASAP-S adapter was ejected into the same orbit. Next, the Fregat stage made two more burns to reach 711 x 714 km and released the Microscope satellite. Operated by the French space agency CNES, Microscope uses the Myriade bus and contains drag-free test masses to test the Equivalence Principle.
  Finally, at 0118 UTC, Fregat made a deorbit burn and reentered over the S Atlantic.
• Signals from all three cubesats were being recieved as of May 4.
