Also called JWS D1
The TacSat-2 demonstrated Orbital's ability to carry out an operationally responsive launch service just six months after the contract award.
It tested 11 different experimental instrument packages designed to give new capabilities to warfighters in southwest Asia.
Right after launch, there were communication problems that could be fixed. First imagery ok.

It carries 11 onboard experiments.
Carries numerous new generation payloads (ESI imager (better than 1 m resolution, 5 km swath width), TIE is a target identifier, CDL is a communication system, ROPE onboard image processing, GPS receiver, etc.)
The Target Indicator Experiment (TIE) consists of a wideband sensor to gather radar, radio and handheld communication signals. The TIE also will check for the automated identification transmission now mandated for large ocean-going ships. The 50 cm optical telescope (0.15° pointing accuracy) will be operated during the satellite's initial day in orbit and throughout the flight to exhibit low-cost, high-quality photography. Runs opensource code derived from the Linux kernel.
