P-1 NOMENCLATURE:
SPACE MODS SPACE
Description (continued):
C. MOD #T7215, MONITOR STATION TIMING SUBSYSTEM ENHANCEMENT (MSTSE): No FY03 funding requested.
D. MOD # TBD, VERSION V MASTER CONTROL STATION (MCS) Upgrade. No FY03 funding requested.
E. MOD #T7199, HIGH POWER AMPLIFIER (HPA). This modification will replace the existing Klystrons and increase the mean time
between failure (MTBF) to approximately 8,000 hours. If not funded, downtime due to Klystron failures will continue to increase, resulting in
inability to upgrade navigation data and satellite commands to the GPS constellation. Inaccurate navigation data will be transmitted to
worldwide civilian and military users resulting in potential losses of life and/or operational equipment, including multi-million dollar satellites.
FY03 funds procure the initial kit, including software changes and system integration.
2. 474N SEA LAUNCHED BALLISTIC MISSILE (SLBM) DETECTION AND WARNING SYSTEM: The 474N SLBM Detection and
Warning System consists of the AN/FPQ-16 Perimeter Acquisition Radar Attack Characterization System (PARCS) and the AN/FPS-123
PAVE PAWS System (Phased Array Radars for SLBM Detection and Warning System). The primary mission is to provide the Cheyenne
Mountain Complex (CMC) with credible tactical warning/attack assessment (TW/AA) data on all SLBMs penetrating the coverage area. This
data includes an estimation of launch and impact locations and times. The secondary mission is to provide the CMC and other users with
TW/AA data on inter-continental ballistic missiles (ICBMs) penetrating the coverage area. Additionally, PAVE PAWS and PARCS support the
Space Surveillance Network by providing space vehicle surveillance, tracking and identification as required by the Space Surveillance Center
and the Joint Space Intelligence Center. The sensors have an operational availability requirement of 98 percent. PAVE PAWS consists of two
operational sites: Site I at Cape Cod, MA and Site II at Beale AFB, CA.
A. AN/FPQ-16 PERIMETER ACQUISITION RADAR ATTACK CHARACTERIZATION SYSTEM (PARCS): The AN/FPQ-16 radar
sensor and the AN/FSQ-100 Data Processing System (DPS) are the two major subsystems which comprise the PARCS system at Cavalier AFB,
ND. The PARCS is a single faced, long range phased array radar whose primary mission is to provide tactical warning and assessment of
SLBM and ICBM attack against North America. This one-of-a-kind system was originally developed in the early 1970’s, and has operated
continuously since 1977.
