DSP Block 14
Defense Support Program
Part of the DSP (Defence Support Program) program
The Block 14 DSP satellites are the third generation of DSP vehicles. Cost is about $180M per spacecraft.
Spacecraft
Spacecraft spin slowly (6 rpm) about the nadir axis to permit scanning of the Earth by the detector system. Zero momentum stabilized using a reaction wheel to counter the spacecraft spin. Four solar panels deploy to generate roughly 1300 W. Radiation hardened.
Payload
Payload classified, but thought to include telescope with 6000 element IR array, nuclear explosion detectors, particle detection monitors.
