Precision Tracking Space System (PTSS)
Abstract
This Program Element encompasses and funds the development of space-borne sensor systems. As threats expand and mature, the need for continuously available sensors and faster interceptors supports investment in a Precision Tracking Space System development beginning in FY 2011. Lessons learned from the two demonstration spacecraft currently on orbit, will guide our decisions on the development of a fiscally sustainable, continuously available, operational precision track space system constellation. The greatest hedge against missile defense threats of greatest concern, regional MRBMs and IRBMs, remains a highly available early missile tracking capability from space. A goal of this effort is to prove the effectiveness of a Precision Tracking Space System by developing, launching and operating a set of prototypes by FY 2014. The Precision Tracking Space System prototype will demonstrate early, precise, real-time tracking of ballistic missiles. This capability significantly improves BMDS performance and the associated functionalities, when approved, will be captured in future BMDS Integrated Build documentation. In the near term, planned terrestrial (surface and airborne) sensor network will be augmented with precision tracking from space. Precision Tracking Space System avoids some of the challenges of terrestrial sensors. Eliminates the need for host nation agreements. Does not require transport to theater or limit our operational flexibility. Limits impacts of weather effects (clouds for airborne, crosswinds and icing, rain for radar). Robust to surprise - can deal with threats arising from unexpected locations or adversaries. Lowers operation and maintenance costs. Observes deep launches. Precision Tracking Space System supports essential BMDS functions by: Continuously observing the regional ballistic missile threat in post-boost. Sending fire-control quality tracks to interceptors - enabling full engagement of the raid. Tracking large raids of nearly simultaneously launched missiles - enabling full engagement of the raid. Providing radiometric data supporting challenging post-boost detection requirements, object classification, and hit/kill assessments. Adding infrared-based tracking to the existing radio frequency sensors in the architecture. Goals for the Precision Tracking Space System are: Develop an operational, end-to-end, missile tracking capability from space focusing on regional MRBMs and IRBMs. Begin the operational approach by developing and testing a space system prototype and integrated ground system with BMDS to precisely track missiles with a sufficient Quality of Service (QOS) (that is, sufficient accuracy and low enough latency) to enable Command and Control, Battle Management and Communications (C2BMC) to provide sensor data to BMDS interceptors to defeat large raids of theater and regional threats. Establish the technical and programmatic foundation for procuring the operational system. Develop space qualified technology to hedge against future missile threat growth.
