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.

[1] VesselSat-2 was launched as a secondary payload on a Long March 4B carrier rocket which was carrying Ziyuan 3.
