Mechanical, thermal and electrical connector interface requirements are contained in this document. These requirements include details of the mounting hole pattern, fastener clearance-hole sizes, and thermal control approaches.

Reporting requirements for mechanical and thermal design data, such as mass, center of gravity, envelope, radiator and heater locations, and so forth are described.

This standard does provide some limited electrical interface requirements. Electrical power service requirements are included in AIAA S-133-5-2013. A more extensive common reference for both standards is AIAA S-122-2007, Electrical Power Systems for Unmanned Spacecraft. This document identifies the significant features of the SPA interface connector(s) and the associated cabling to allow SPA device and cable manufacturers to build systems that interconnect successfully with SPA-enabled spacecraft. The connector type and pin assignments are described, along with definitions of connector gender and mechanical mounting. Requirements are provided for the associated cabling, including details of shielding, shield termination, insulation and cable impedance

Optional SPA connector interfaces are described in the following sections by type (i.e., Type A, Type B, etc.).
