AEROSPACE VEHICLE
The HEXAGON Satellite Vehicle is launched by the Titan HID Booster Vehicle. When
mated together, the entire assembly is termed the Aerospace Vehicle.
The Aerospace Vehicle is launched from Space Launch Complex -4 East, Vandenberg
Air Force Base. The Solid Rocket Motor, Stage I and Stage II are stacked at the launch
site and functionally tested. The complete SV including the shroud is mated to the
booster vehicle fourteen (14) days prior to launch. The Aerospace Vehicle is then func-
tionally checked and all propellants and gases are loaded.
The booster vehicle can place 24,800 pounds into an 82 x 144 nm (perigee x apogee) orbit
with an inclination (-97 degrees) that provides the nearly sun synchronous condition
needed for long life missions.
