Summary
ORBCOMM FM19, also known as Orbcomm B7, is a communication satellite designed for Machine-to-Machine (M2M) and Internet of Things (IoT) applications. Launched on August 2, 1998, from the Eastern Range Air Station using the Pegasus XL/HAPS launch vehicle, it has a NORAD catalog ID of 25415 and an object ID of 1998-046C. The satellite is owned by ORBC and manufactured by OSCG (Orbital Sciences Corporation). It measures 0.2 meters in length with a diameter of 1 meter and spans 4.3 meters due to its deployable solar arrays. Its dry mass is 42 kilograms, the same as its launch mass, indicating no fuel was carried for maneuvering. The satellite is equipped with an Orbcomm payload and powered by two deployable solar arrays and batteries. It has a cylindrical shape with two panels and antennas and operates in space to provide communication services, with an expected lifetime of four years.
