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
