ORBCOMM OG2 Next-Generation

Satellite Constellation

SNC is the prime contractor for ORBCOMM's Generation 2 (OG2) satellite constellation – responsible for the design, manufacture and integration of all 17 OG2 satellites in the constellation. Each OG2 satellite is based on SNC's flight-proven SN-100 satellite bus platform, which can be tailored to support a variety of applications.  All aspects of payload integration, system-level performance and environmental testing are accomplished in-house at SNC's Louisville, Colorado facility. In addition to the design and build, SNC also supports launch operations, in-orbit testing and commissioning the satellites into network service from its Satellite Operations Center in Louisville.

The OG2 constellation significantly enhances ORBCOMM's existing service capacity, offering up to six times the data access and twice the transmission rate of the legacy ORBCOMM Mission 1 (OG1) satellites -- providing faster message delivery, larger message sizes and better coverage across latitudes. The OG2 constellation enables worldwide machine-to-machine (M2M) communications for commercial customers as well as Automatic Identification System (AIS) data for the U.S. Coast Guard and other users.
