The RQ-1A/B Predator is a system, not just aircraft. A fully
operational system consists of four aircraft (with sensors), a
ground control station (GCS), a Predator Primary Satellite Link
(PPSL), and 55 personnel for continuous 24 hour operations.
The basic crew for the Predator is one pilot and two sensor
operators. They fly the aircraft from inside the GCS via a C-Band
line-of-sight data link or a Ku-Band satellite data link for
beyond line-of-sight flight. The aircraft is equipped with a
color nose camera (generally used by the aerial vehicle operator
for flight control), a day variable aperture TV camera, a
variable aperture infrared camera (for low light/night), and a
synthetic aperture radar (SAR) for looking through smoke, clouds,
or haze. The cameras produce full motion video and the SAR still
frame radar images. The three sensors are carried on the same
airframe but cannot be operated simultaneously.
In the future, Predators will carry the Multispectral Targeting
System (MTS) with inherent AGM-114 Hellfire missile targeting
capability, and integrates electro-optical, infrared, laser
designator and laser illuminator into a single sensor package.
These Predators cannot carry MTS and the SAR simultaneously. The
aircraft will carry and employ two laser-guided Hellfire
anti-tank missiles with MTS.
Each Predator aircraft can be disassembled into six main
components and loaded into a container nicknamed "the coffin."
This enables all system components and support equipment to be
rapidly deployed worldwide. The largest component is the GCS and
it is designed to be rolled into a C-130. The air transportable
PPSL consists of a 6.25 meter Ku-Band satellite system mounted on
a trailer. It provides communications between the ground station
and the aircraft when it is beyond line-of-sight and is a link
into secondary intelligence dissemination networks. The RQ-1B
system needs 5,000 feet by 125 feet (1,524 meters by 38 meters)
of hard surface runway with clear line-of-sight to each end from
the GCS to the air vehicles.
The RQ-1B includes an ARC-210 radio, an APX-100 IFF/SIF with Mode
4, an upgraded turbo-charged engine and an ice mitigation
system.

The "R" is the Department of Defense designation for
reconnaissance; "Q" means unmanned aircraft system. The "1" refers
to it being the first of a series of purpose-built unmanned
reconnaissance aircraft systems. An "A" or "B" that follows the 1
states the version of the RQ-1 system series.
The Predator system was designed in response to a Department of
Defense requirement to provide persistent intelligence,
surveillance and reconnaissance information to the warfighter. It
was the first successful advanced concept technology
demonstration. This is a new acquisition process designed to
reduce costs and development time by relying on
commercial-off-the-shelf and government-off-the-shelf technology
to the maximum extent possible. In April 1996, the secretary of
defense selected the U. S. Air Force as the operating service for
the RQ-1A Predator system. Operating responsibility is at the
11th, 15th and 17th Reconnaissance Squadrons, Indian Springs Air
Force Auxiliary Field, Nev.
