P-PODs packaged as a secondary payload.
-high capacity (24U-50U)
-leverages mature technology
-multi-LV compatible
-low risk to primary payload or other secondary payloads
This is the Coach Class Section!

NPSCuL-LITE Test Program
Structure Qualification– Launch environments +6dB using Mass Models to
simulate loaded P-PODs– Must accommodate minimum expected CubeSat
mass (1 kg/U)– NPS will perform all structural tests
Functional Developmental Testing– On-board electronics fire the deployment
systems in sequence– Currently in development by a launch provider– NPS to develop mission specific electrical
harnesses

Sequencer Design
Requirements:
•28V power from LV
•RS-422 programming interface
•8-channel redundant output

Program Progress To Date
NPSCuL-Lite– Qualification Test structure
produced and assembled.– Mass model of sequencer unit has
been integrated – Structural and TVAC testing to
begin shortly.P-POD Mass Models
– 9 units produced– design went through a thorough
qualification test batterySequencer – development by industry is
underway.

Future of NPSCuL/NPSCuL-Lite
Potential flight opportunity exists in 2010. To support this opportunity:– Flight Article Build – through DEC 2009– Harness Design and Build – through JAN 2010– Acceptance Test– no later than March 2010
• Requires sequencer and 8 integrated, flight-ready P-PODs– Launch Vehicle Integration – April 2010– 1st Launch – August 2010
2nd Flight Opportunity – Possible slot on an ESPA ring expected in 2012– NPS will seek to fill any unfilled slots with payloads from
University developers
