In the frame of ESA Integrated Applications Programme, SkyfloX runs the co-funded project DOCS: Demonstration of ORCA Constellation Services. A first major milestone confirming ORCA’s exceptional capabilities was achieved early October at the critical design review at the European Space Research and Technology Centre (ESTEC) in Noordwijk, Netherlands. SkyfloX and partners achieved this milestone in merely five months from the DOCS project kick-off in May 2017. The next step is the flight test campaign planned at the end of 2017.
