VesselSat-1 (Orbcomm FM42, V1) was a miniaturized satellite built and owned by LuxSpace, which was operated by Orbcomm under lease. VesselSat-1 and its sister satellite, VesselSat-2 were used by Orbcomm to compensate the functionality of the malfunctioning Orbcomm-QL satellites.
It was launched from the ISRO's Satish Dhawan Space Centre (SDSC) at Sriharikota in October 2011 atop a PSLV-CA rocket, flight C18. The launch was a multi-payload mission along with Megha-Tropiques, SRMSAT and Jugnu.
Vesselsat was the first satellite to be built in Luxembourg. It had a mass of 29kg (64lb) and had the form of a cube 30cm (10inches) along each side. Its mission was the tracking of shipping by receiving broadcasts from their Automatic Identification System (AIS).
