Orbcomm 30

 1999-065A


Dec 1999 saw the launch of seven Orbcomm satellites from Wallops. The satellites had originally been planned for equatorial launch to 1000 km from ETR and had 2 kg extra radiation protection, so eight satellites were taken off the launch and put in storage. The satellites were launched into plane A as with the Dec 1997 launch. Total weight 408 kg including HAPS estimate of 100 kg.
