SECTION 1: INTRODUCTION
The Capricorn 2000 System
The Pegasus FlyAway Kit portable weather station combines digital
quality and professional-grade equipment with the need for a highly
mobile weather station to create a state-of-the-art, rapid deployment
weather monitoring system for Emergency Operations.
Pegasus is specifically designed for firefighters, HazMat,
Emergency Management, and Disaster Preparedness personnel
when weather monitoring is crucial to the public’s safety.
Pegasus allows Accident and Incident Commanders to create a fully
functional weather operation within minutes, automatically collecting
weather data and providing a cost-effective force-multiplier not
available in any other portable weather station.

Control Module
The Control Module consists of the System board and a 2.4 GHz
transceiver housed in a weatherproof fiber glass enclosure with
external sensor and power connectors.
The System board has an on-board barometric pressure sensor and
a system fuse (including a spare fuse). The System board also has
in-line rechargeable batteries to preserve the datalog and system
configuration when power is absent.
The Control Module dimensions are: 14 x 11 x 6.5 inches and
weighs: 6.7 lbs/3 kg.
Control Module Connections

Wind sensor
The wind speed and direction sensors use a solid state, infrared
optical design to decrease wear and improve reliability. These
rugged sensors, with a design incorporating years of experience
and testing, are enclosed in a rugged PVC housing surrounding
stainless steel parts. These sensors operate in extreme temperature
and wind conditions for years.

Temperature sensor
The Pegasus comes standard with one temperature sensor with 10
feet of cable. This digital, semiconductor-type probe reduces
susceptibility to noise interference, and increases accuracy. The
sensor is calibrated at the factory traceable to NIST standards.

Relative Humidity sensor
This optional capacitive relative humidity sensor is compact and
easy to use. It is easily installed in the self-aspirating radiation shield
for protection from the sun and rain. This sensor offers long-term
stability with minimal drift. Because the sensor is a capacitive
device, it will not be affected by surface contamination in unclean
environments. Since the sensor element is socketed and laser
trimmed it can be easily replaced in the field without any additional
calibration. The relative humidity sensor comes with a standard 10-
foot cable and a quick disconnect connector.

secure support for your meteorological sensors.
The T-1000 is constructed from welded aluminum and is powder
coated for appearance and longevity. The 15-pound tripod can

easily support up to 60 pounds of equipment. The tie-down kit
allows for additional security in high-wind areas.
Set up takes less than five minutes. Simply insert the legs into the
main body and install the stainless steel retainer pins. Extend the
mast to the desired height and insert another retainer pin. Install
the guy wires and you’re ready to go!
