GENERAL
1.1 Introduction
This publication provides technical information for the ISAT-100 Position/Data
Communicator (Mod AB), developed by SkyTrac Systems Ltd. The ISAT-100 will
provide voice communication, position reporting and messaging with global coverage
in near real time.
1.2 Description
The ISAT-100 contains a GPS (Global Positioning System) receiver, an L-Band
transceiver specifically designed to communicate with the Iridium
®
satellite system, a
battery which enables communications with the satellite system after airframe power
shutdown and a battery charging system. Control and interfacing is provided with a
low power single-board computer.
The ISAT-100 has been tested to the RTCA/DO-160D environmental categories
listed below. The tests demonstrated that the ISAT-100 does not exhibit any unsafe
performance when exposed to the specified environmental test conditions, and that
installation of the ISAT-100 in accordance with the installation instructions in this
Manual will not pose a hazard to the continued safe flight and landing of the aircraft.

1.3 Purpose of Equipment
The ISAT-100 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 having Internet access, via the Iridium
®
Low Earth Orbit (LEO)
satellites. Present position 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).
Operationally, the ISAT system can compliment flight following requirements for
commercial operators and provide vital position data and messaging services to
those operators conducting flight activities in remote areas.
