Adaptor upper stage flight opportunity


A new affordable and reliable opportunity to deliver payloads to GEO orbit.

GMP-A is an innovative satellite platform that optimizes the unexploited spare capacity inside the adapter cone of the launch vehicle, under the primary payload.

GMP-A is designed to fit neatly inside the restricted space available, and has no impact on the primary payload or the fairing design. Once launched, it deploys antennae and solar panels and utilizes electric propulsion to complete the journey to GEO orbit, where it reconfigures the antennae and solar panel orientations for start of operations.
