USNDS 7

Abstract

USNDS 7 consists of an ICADS 7 satellite ground data processing system and UGNT trailers that accommodate new NDS payload on GPS IIIF family of vehicles and are an upgrade to the current USNDS 6 program. USNDS 7 ICADS reports endoatmospheric, transition and near-space nuclear detonations as detected by the USNDS sensors aboard the GPS satellites, DSP satellites and SABRS equipped satellites. ICADS Build 7 process NDS, State-of-Health (SOH), and navigation data from GPS IIIF. USNDS 7 UGNT provide NUDET Detection Reports to end users through survivable/endurable USNDS communications via Milstar/AEHF circuits. USNDS 7 also consists of the Integrated Data Denial (IDD). IDD is a Communications Security (COMSEC) device associated with the USNDS. IDD provides decryption of satellite position data and NDS sensor data used to detect, locate, and report nuclear detonations in earth's atmosphere or near-space in near real time. This IDD effort contains cryptographic modifications mandated by National Security Agency (NSA). In addition, parts obsolescence requires the start of a new IDD design and manufacturing effort.
