Mission Objectives
1. Demonstrate the ability to rapidlydesign and develop militarily relevant
low cost spacecraft.
2. Primary Operational Objectivea. Scenario OV-1. Receive packetized
data from multiple Unattended GroundSensors (UGS). Transmit that data toground stations within the SMDC-ONEground track.
3. Secondary Operational Objectivea. Scenario OV-2. Provide real time voice
and text message data relay to andfrom field deployed tactical radiosystems.
4. Demonstrate SMDC-ONE operationallife time of 12 months or longer.
Mission Objectives
1. Design, develop, and deliver eightSMDC-ONE satellite systems within 12
months of ATP (April 2008) for ahardware cost not to exceed $350k persatellite.
2. Receive UGS signal on two or moreSMDC-ONE satellites and successfully
relay that signal to a deployed groundstation.*
3. Not required for mission success.
4. Demonstrate an on-orbit operationallife of 6 months or longer.**
Minimum Success Criteria
Dependent upon launch of 8 satellites** Dependent upon assigned orbit
