Payload Software Integration and Verification 
Facility (PSIVF) Overview
• PSIVF is located at MSFC, Building 4755
• PSIVF provides an emulation of the payload C&DH avionics architecture 
for payload software interface checkout
• Payload Developer Interaction with PSIVF
• EXPRESS Laptop Computer Payload Application Software (PAS) is tested at 
PSIVF for compatibility (with other payload software) and interface verification
• Environment is available to support EXPRESS Rack and EXPRESS Logistics 
Carrier payload software development testing
• Interface to Huntsville Operations Support Center (HOSC) can be 
established to check out command and telemetry flow
• Payload software functions performed by the PL MDM (Timeliner Scripts, 
Parameter Monitoring) can be simulated
• Resolution or troubleshooting for On-Orbit payload software anomalies 
can be supported
• Planning for PSIVF testing can be 
coordinated by your Payload 
Integration Manager (PIM)
•PSIVF Point of Contact:  Jill Travers,
