VesselSat-2 (aka Orbcomm FM43, V2) was a Luxembourgian microsatellite built and owned by LuxSpace, and operated by Orbcomm under lease. It carried a receiver for Automatic Identification System signals, used to track ships at sea. VesselSat-2 was the second of two VesselSat spacecraft (see VesselSat-1), which were built by LuxSpace for Orbcomm, as replacements for the AIS capabilities of the failed Orbcomm-QL spacecraft.
VesselSat-2 was launched as a secondary payload on a Long March 4B carrier rocket which was carrying Ziyuan 3. The launch occurred at 03:17 UTC on 9 January 2012, from Launch Complex 9 at the Taiyuan Satellite Launch Centre, and was the first orbital launch of the year.
