SPACE TEST PROGRAM’S STANDARD INTERFACE VEHICLE
Rapid & affordable access to space
Payload teams are able to design payloads and specific experiments to be compatible with the flexible standardized vehicle, resulting in lower spacecraft non-recurring costs and increased spaceflight opportunities. By providing such a vehicle, the Space Test Program can shorten acquisition timelines and decrease spacecraft build costs for its defense industry customers.
The first STP-SIV spacecraft, STPSat-2 launched Nov. 19, 2010 aboard a Minotaur IV from Kodiak, Ala. The satellite is carrying a relay transponder for data collected by ocean buoys and a space phenomenology sensor. STPSat-3, the second STP-SIV spacecraft, carried five payloads and was successfully launched Nov. 19, 2013 on a Minotaur I from Wallops Island, Va.
What We Did
Spacecraft provider, integration & test lead
We built STPSat-2 in just 47 days. Construction of the satellite platform was completed before the final payloads had been selected, demonstrating the flexibility of the hardware.
The STP-SIV series of satellites is based on the Ball Configurable Platform (BCP) 100, which is ideal for a variety of science, technology development and risk reduction missions. Accommodating up to four separate instruments, the STP-SIV is easily adaptable for future missions with no design changes necessary for payloads that conform to the standard interface. Additionally, the STP-SIV maintains flexibility to launch on a large variety of vehicles, including the EELV Secondary Payload Adapter
