Session III: Where We're Going Section 2
Abstract
STP shares a fundamental goal with other government organizations to lower costs and increase speed and reliability of access to space. On the way to achieving this goal, STP is procuring a common spacecraft (SC) identified as the Standard Interface Vehicle. The STP-SIV program intends to shorten acquisition timelines and SC build time, reduce non-recurring costs, applying lessons learned from SC to SC, facilitate payload integration and increase flight opportunities. This program provides for up to six spacecraft of ~180 kg in mass, measuring ~60.9cm x 71.1cm x 96.5cm, with standard interfaces for mechanical, thermal, power and data to support up to four payloads totaling ~60 kg. The space vehicle (SV) shall be designed for orbits ranging from 400 to 850 km, inclinations of 0 to 98.8 degrees, and leverages the ESPA and small launch vehicles. The acquisition approach applies a flexible Indefinite Delivery, Indefinite Quantity (IDIQ) contract for rapid acquisition of SC to quickly respond to DoD needs, uses low risk existing technologies to build low cost spacecraft, and takes advantage of lessons learned from one SV to the next. The design philosophy is to use flight-proven hardware for the SC and developmental hardware only for the experimental payloads.
