. Integrated Surveillance Towers (IST) Consolidated Tower & Surveillance Equipment (CTSE) Award   4

The IST Program will use the CTSE IDIQ contracts to acquire medium and long-range surveillance towers. These surveillance towers will be comprised of multiple subsystems that allow U.S. Border Patrol agents to continuously detect, identify, classify, and track Items of Interest (IoI) 24 hours a day, seven days a week within each tower system's area of coverage under typical operating conditions found along the southern and northern borders. Each CTSE surveillance tower will be customized to the threat and operational/ environmental conditions of the Border Patrol Station Area of Responsibility (AoR) in which they will be deployed. CTSE consists of the following subsystems: Tower subsystem, Power subsystem, Instrumentation subsystem, and Communications subsystem. The IST Program will acquire approximately 277 new IST towers in 53 separate USBP AoRs and upgrade approximately 191 legacy surveillance towers in 31 separate AoRs.
