Space Based Space Surveillance: Follow On Needed
In January 2001, a commission headed by then US Defense Secretary-designate Donald Rumsfeld warned about a possible “space Pearl Harbor” in which a potential enemy would launch a surprise attack against US-based military space assets, disabling them. These assets include communications satellites and the GPS system, which is crucial for precision attack missiles and a host of military systems.
“The US is more dependent on space than any other nation. Yet the threat to the US and its allies in and from space does not command the attention it merits,” the commission warned.
One of the systems that grew out of the commission’s report was the Space Based Space Surveillance (SBSS) project, which is developing a constellation of satellites to provide the US military with space situational awareness using visible sensors. After a slow start, SBSS Block 10 reached a significant milestone in August 2012 with its Initial Operational Capability, followed by full operational capability less than a year later. But lack of funding casts as shadow on whether this capability will be maintained beyond 2017. By 2014/15 the Air Force worked on a stopgap project as well as an effort to obtain proper funding for follow on satellites to be launched at the start of next decade.
Space Tracking
The SBSS system is intended to detect and track space objects, such as satellites, anti-satellite (ASAT) weapons, and orbital debris, providing information to the US Department of Defense as well as NASA. The SBSS is a stepping stone toward a functional space-based space surveillance constellation.
The SBSS is a follow-on to the Mid-Course Space Experiment/ Space-Based Visible (MSX/SBV) sensor. The initial SBSS satellite is expected to improve the US government’s ability to detect deep space objects by 80% over the MSX/SBV system.
The MSX/SBV system was a late 1990s missile defense test satellite; by 2002 most of its sensors had failed. However, 1 small package called the SBV sensor was able to search and track satellites in geosynchronous orbit (GEO) using visible light. This sensor lowered the number of “lost” objects in GEO orbit by a factor of 2.
Building on the success of the MSX/SBV visible sensor, the SBSS Block 10 further develops the technology and replace the SBV sensor. Block 10 involves the development of 1 satellite as a pathfinder for a full-constellation of space-based sensors.
The SBSS Block 20 constellation is expected to include 4 satellites when fully developed and the SBSS constellation was originally expected to be operational in FY 2013.
However, delays have plagued the system. In late 2005, an independent review team found that the program’s baseline was not executable; that the assembly, integration, and test plan was risky; and that the requirements were overstated. The SBSS program was restructured in early 2006 due to cost growth and schedule delays. The restructuring increased funding and schedule margin; streamlined the assembly, integration, and test plan; and relaxed requirements. The launch of the initial satellite was delayed and costs increased by about $130 million over initial estimates.
Northrop Grumman, the prime contractor for the SBSS system, awarded a Boeing-led team that includes Ball Aerospace and Harris Technologies a contract to develop and deploy the Block 10 SBSS Pathfinder satellite and ground system. The program itself was back on track, but funding for follow-on was then nixed several years in a row.
Contracts and Key Events
December 13/18: Sustainment Boeing is being awarded with a contract modification to sustain the US Air Force’s Space Based Space Surveillance (SBSS) Block 10 system. Worth $22.7 million the modification exercises a contract option for sustainment and required development to keep the SBSS running. Required efforts include systems engineering, operations, operations support, and contractor logistics support. SBSS is intended to detect and track space objects, such as satellites, anti-satellite (ASAT) weapons, and orbital debris, providing information to the US DoD as well as NASA. The Block 10 satellite operates 24-hours a day, 7-days a week collecting metric and Space Object Identification data for man-made orbiting objects without the disruption of weather, time of day and atmosphere that can limit ground-based systems. Work will be performed at Boeing’s factory in El Segundo, California and in Colorado Springs, Colorado. Performance is expected to be completed by June 2022.
June 19/15: The Space Based Space Surveillance Block 10 program benefited from a $11.5 million contract with Boeing on Thursday, with this to provide sustainment and development work. The SBSS program needs a follow-on to the existing satellites in orbit, with the Air Force arranging an industry day in January in order to present its acquisition strategy. Principally this involves the planned procurement of three new satellites, with a rough schedule of these entering service before 2021.
Jan. 2015: SBSS FO revival? The SBSS program office plans to hold an industry day on January 22 in El Segundo, CA to discuss their acquisition strategy for the satellite’s stalled follow on. Air Force Space Command has sought $251 million over the FY16-19 FYDP to restart work on a program involving 3 smaller satellites in low Earth orbit, with the 1st launch around 2021 or 2022. It’s not the size of the sats that matters to provide real-time, all-weather access, but rather their orbital position.
Attendants will also be debriefed on the Operationally Responsive Space (ORS) latest results with the ORS-5’s System Capability Demonstration, an effort involving the Massachusetts Institute of Technology-Lincoln Laboratory that may bridge the gap between SBSS’ end of life and the launch of its follow on.

March 2014: follow on delayed. The US Air Force’s FY 2015 budget request delays delivery of the SBSS follow-on by a year, which suggests that it’s not entirely dead, but rather frozen.
April 2013: follow on cancelled. As per the USAF’s RDTE FY 2014 budget request, “the SBSS Follow-on program was terminated in FY14 and beyond to pay for higher department priorities.” This is not a surprise as Congress had already cut into follow on funding as early as FY11.
April 1/13: FOC. US STRATCOM declares that the SBSS satellite has reached Full Operational Capability.
Aug 20/12: Air Force Space Command declares Initial Operational Capability (IOC) for the Space Based Space Surveillance Block 10 satellite. IOC marks a certain level of program maturity within the Production and Deployment (P&D) phase of the acquisition lifecycle. This follows an IOT&E phase conducted in March-April 2011 that DOT&E found adequate [PDF].
According to the GAO’s FY2012 report on space acquisitions, the Air Force decided to wait before asking for follow-up funding given the size the funds required, but this might be in play for FY2013.
IOC
Feb 23/11: The SBSS satellite begins full operational duty within the Air Force’s 1st Space Operations Squadron in the 50th Operations Group, 50th Space Wing, Schriever Air Force Base, Colorado.

Feb 5/09: Boeing announced that it successfully completed initial satellite testing and demonstrated end-to-end mission functionality of the ground and space systems of the integrated Space Based Space Surveillance (SBSS) system.
The SBSS team demonstrated end-to-end mission functionality starting with the generation of mission plans in the Satellite Operations Center at Schriever Air Force Base, CO, in response to simulated tasking. These plans were sent via the encrypted Air Force satellite control network to command the flight space vehicle in Boulder, CO, to take images using the payload optics. The Boeing-led team also demonstrated progress toward operational readiness by completing the second full mission exercise. The exercise employed a mission scenario using the SBSS ground segment and a space vehicle simulator.
April 21/08: The Space Based Space Surveillance (SBSS) System Block 10 team announced completion of the payload electronics, high-speed gimbal and testing of the space vehicle’s visible sensor, enabling the start of payload integration and test.
The SBSS gimbal and visible sensor enable responsive tasking as events in space warrant. The Boeing-provided onboard payload computer performs immediate detection of space objects and provides future capability for improved Block 10 performance.
Dec 11/07: Boeing announced that it had successfully completed a series of Space Based Space Surveillance (SBSS) system tests as part of the development of a new operational sensor for the U.S. Space Surveillance Network.
Tests of the SBSS system’s visible sensor, payload electronics and high speed gimbal further validate that the enhanced capability of SBSS will be twice as fast, substantially more sensitive and 10 times more accurate than the capabilities currently on orbit, resulting in improved detection of threats to America’s space assets.
