Attch 4 ROTHR SAASM PPIP.pdf

This document is a Program Protection Implementation Plan (PPIP) for the Relocatable Over-the-Horizon Radar (ROTHR) Selective Availability Anti-Spoofing Module (SAASM) Time and Frequency Receiver. The plan details the security and protection measures for a GPS receiver system deployed at sites in Puerto Rico, specifically at Juana Diaz and Vieques.

Key technical details include the use of a Symmetricom XLi GB-GRAM SAASM Time and Frequency Receiver, which can receive both military and civilian GPS signals and incorporates an Anti-Spoofing Module. The sites are located on military bases with 24/7 surveillance, NSA-approved cipher locks, and multiple security layers. The system supports a narco-terrorism surveillance mission, providing wide area air and sea tracking information. The plan is prepared by Raytheon Technical Services Company in coordination with the USAF Global Positioning Systems Wing, with personnel holding Secret security clearances and following strict government security classification guidelines.
