1.3 ISAT-200 System Components
The following paragraphs describe the components of the ISAT-200 system.
1.3.1 ISAT-200
The ISAT-200 is the primary component of the ISAT-200 System. The system is comprised of a
GPS (Global Positioning System) receiver, an L-Band transceiver specifically designed to
communicate with the Iridium
®
satellite system, a Lithium-ion battery which enables communications
with the satellite system after airframe power shutdown, and a battery charging system. Control and
interfacing are provided with a low power, single-board computer.
The ISAT-200 provides position reporting and messaging with global coverage in near real time.

The ISAT-200 is the primary hardware component of a system designed to provide full duplex sat
phone communication, automatic message reporting, 2-way messaging and other data transfers.
Data can be sent between an aircraft and any point in the world with internet access via the Iridium
®
Low Earth Orbit (LEO) satellites. Position reports and text messages from the aircraft can be
displayed on any computer with internet access and SkyTrac software. Position reporting intervals
are user-defined. Base software displays current and historical position data including latitude,
longitude, GPS time, relative position (to a known way point), ground speed, altitude and heading, in
tabular format and on a map. Airtime, flight time, ETA, distance traveled, time elapsed and other
flight data is also displayed for instant viewing. Flight reports can also be generated by unit and time
frame (i.e. airtime/flight time per day/week/month).
