PFRR Administration Center
Poker Flat Research Range has five major
>launch pads. Pads 1 and
2 each have a 7.5K launcher, pads 3 and 4 each contain 20K MRL launchers, and
pad 5 contains a 4K twinboom launcher. Pad 3 and 4 are equipped with moveable
launcher enclosures which are used to protect rockets on these pads and the
workers from the severe winter weather.
The range facilities include an operations and office building, a 40 x 50
foot launch-control blockhouse complex, a 50 x 50 foot payload assembly
building with a Class-100 cleanroom, a 285-foot instrumented meteorological
tower, minicomputers to calculate wind weight parameters, and other buildings
for rocket storage, assembly, and various operations and maintenance
Range telemetry support is provided by three S-band auto-track systems,
incorporating an 8-foot an 11-meter and a 16-foot dish, provided by NASA and
located on Middle Range. PFRR also
contains a C-Band NASA Radar for vehicle tracking, surveillance radar for
local air traffic, and a meteorological balloon inflation building.
Additionally, the range has Transportable Orbital Tracking System (TOTS), the
Redstone Antenna, and PF1 (Datalynx) used primarily for satellite tracking.
Poker Flat is connected to the Geophysical Institute by means of a digital
microwave system which has a 45 Mbit/s (DS3) capacity. The fully-redundant
microwave system provides the data channels (including Internet access) and
most of the telephone circuits used at PFRR. Poker Flat is also connected via
fiber optic link to the Geophysical Institute.
The LIDAR Observatory hosts LIDAR
experiments, and the T. Neil Davis Science Operations Center, which houses
magnetometers, riometers, all-sky auroral cameras, a meridian-scanning
photometer, a Fabry-Perot interferometer, and other observing instruments
such as the low-light color television camera and video recorder for auroral
research. Local tropospheric measurements are made at the Climate Change
Monitoring station. Downrange observatories exist at Fort
Yukon, Kotzebue, Kaktovik on the Arctic Ocean and Spitzbergen.
