ST200 Series Technical Support Manual 1January 2000
1.0 Introduction
This manual provides the basic information required to successfully sell, distribute, and maintain
the Mitsubishi ST200 Series satellite terminals. The ST200 Series include the following
configurations:
•ST211 land mobile
•ST221M fixed site
•ST251 OmniQuest®transportable
This document, ST200TSM02, replaces all Technical Support Manuals previously published by
Mitsubishi Electronics America, Inc. (MELA) as it combines and updates the contents of the
ST200TSM01 and the ST251TSM01 into one comprehensive manual.
Distributors and other sales/service agents should use this reference document for training staff
and addressing typical questions and problems from the field. Two portions of this manual
warrant special attention: Sections 8.0 and 9.0. The first details MELA’s product support
policies and procedures. The second describes key operational considerations that can prove
useful in addressing frequently asked questions. This manual is posted on MELA’s web site
(www.melamsat.com) in PDF format. Distributors are encouraged to download, print and
distribute copies to all personnel involved in the MSAT business.
For consistency with previous manuals and concise notation this document uses the terms
Mobile Terminal (MT), Mobile Earth Terminal (MET), satellite terminal, satellite
communications system and satellite telephone interchangeably.
2.0 System Overview
The Mitsubishi mobile satellite telephone products are designed to work on the MSAT (L-Band)
satellite system anywhere in North and Central America including Alaska, Hawaii, the
Caribbean, and 200 miles of coastal waters. There are currently three satellite network
providers: American Mobile (AMSC) located in Reston, Virginia, TMI Communications Ltd.,
located in Ottawa, Canada and Telecomunicaciones De Mexico (Telecom), located in Mexico
City, Mexico. The Mitsubishi MSAT products addressed in this manual are sold and distributed
in North and Central America by authorized distributors and resellers.
The MSAT system comprises a satellite segment, communications ground segment (CGS) and a
mobile terminal segment.
2.1 Satellite Segment
The satellite segment acts as a relay site, similar to a cellular communications base station. It
passes signals to and from the CGS and MTs. AMSC launched its satellite (AMSC-1) into

MITSUBISHI ELECTRONICS AMERICA, INC.
ST200 Series Technical Support Manual 2January 2000
geosynchronous orbit (~ 22,300 miles / 36,000 km altitude). The MSAT satellite is one of the
most powerful communications satellites on-orbit (>500,000 Watts) and is capable of seamless
North American and Central American coverage. Hughes Communications designed the MSAT
satellite with relatively large antennas, allowing for relatively small MT antennas.
2.2 Communications Ground Segment
The CGS routes all MT calls and provides the interface to the Public Switched Telephone
Network (PSTN). The ground segment also provides feeder communications to the satellite,
establishes channels for end-user calls, and managing system resources. AMSC’s CGS is
located at AMSC headquarters in Reston, Virginia with a backup facility located 26 miles south
of this location. TMI’s CGS is located in Ottawa, Ontario and Telecom’s CGS is located in
Mexico City.
CGS subsystems include the Feederlink Earth Station (FES), Network Communication
Controller (NCC), and Network Operations Center (NOC). The FES links the signaling channels
between the satellite and the NCC and communications channels between the satellite and the
PSTN. The NCC uses these signaling channels to manage all communication system resources
through a variable number of Control Groups (CG). Each control group uses specific signaling
channels for specific MTs. The NOC oversees the entire operation, including billing and
customer service.

2.3 Mobile Terminal Segment
As end-user equipment, MTs transmit and receive signals to and from the CGS via the satellite.
MSAT terminals include land mobile, transportable, fixed, maritime, and aeronautical
applications. Each Mitsubishi MT comprises three functional units: Antenna Unit (AU),
Transceiver Unit (TU), and one or more user interfaces (like handsets or a personal computer).
3.0 Product Overview
3.1 General Overview
The ST211 terminal includes a transceiver, beam steering unit, and handset or user terminal
options. The beam steering unit is a small gyroscope that determines vehicle motion for mobile
satellite tracking.
The ST221M fixed site terminal comprises the same major components as the land mobile
configuration, minus the beam steering unit. The parabolic antenna in this high gain
configuration replaces the dome type antenna in the land mobile unit. The ST221M also
includes an AC/DC power supply.
Standard items and optional accessories provide basic digital voice, wide area dispatch and data
capabilities. Mitsubishi land mobile and fixed site antennas physically incorporate the radio
frequency electronics, easing installation and troubleshooting. The following figures show the
primary elements of the ST211 and ST221M configurations respectively.

The ST251 OmniQuest®transportable terminal is one of the most versatile satellite
communications systems available to date offering many unique features and capabilities.
OmniQuest® is an integrated portable terminal containing the transceiver, antenna, battery and
handset as depicted below.

3.2 Key Features
All Mitsubishi MTs are easy to operate. The basic handset, for point-to-point calling, looks and
operates like a cellular phone. There are three one-touch speed dial keys and 99 alphanumeric
memory locations. The handset permits any key answering, displays received signal strength,
and lets users enable special features from a menu of functions. Optional accessories also allow
users to operate in a hands-free mode.
All MTs accommodate service offering for wide area dispatch with an optional push-to-talk
handset (shown above) and circuit switched data at 4800 bits per second.
Three new features have been added to these second-generation MTs: Horn Alert, Auto-Power-
On and Echo Cancellation. Horn Alert is ideal for those with Land Mobile applications who
need to be able to hear the MT ringing while away from their vehicle but while still nearby.
Auto-Power-On allows the user to set the MT to automatically power on once the vehicle’s
engine is started (just like a car radio when left on). The software–based echo cancellation
feature allows users to avoid having to install an echo canceler board in the TU.
3.3 Product Positioning
The mobile, fixed and portable terminals deliver communication where there is no existing
infrastructure; or when other systems fail or become overloaded. These MTs do not compete
with terrestrial offerings like cellular or PCS. However, for those companies and industries that
need seamless communication, Mitsubishi MTs are a viable solution. Seamless coverage and a
flat airtime rate are important for prospects who operate in multiple locations on an on-going
basis.
These MTs offer top-notch brand name recognition, reliability, and quality that Mitsubishi
supports with an in-warranty replacement program.
3.3.1 Target Markets
Mitsubishi mobile, fixed and portable configurations effectively address several niche markets:
♦Industries that operate expansive networks like telecommunications, energy, and
utilities can more efficiently manage their field units with Mitsubishi land mobile
terminals.
♦Remote site industries, like those involved in construction or natural resource
extraction, can employ Mitsubishi fixed site MTs for communicating with isolated
management or operation centers. This market also extends to the tourist industry
with remote hunting and fishing lodges.
♦All configurations also address large corporations or institutions—that because of
geography or regulation—require back-up or contingency communications.

MITSUBISHI ELECTRONICS AMERICA, INC.
ST200 Series Technical Support Manual 6January 2000
Companies in California and Florida in the US and other locations throughout Canada
and Central America are especially receptive to this concept. Further, companies
involved in transporting or working with hazardous materials like nuclear power
generation and HAZMAT transportation must have an emergency mode of
communications.
3.3.2 Applications
Specific MSAT applications for land mobile, fixed site and portable MTs exist throughout North
and Central America today. The following examples may provide some additional insight for
sales and marketing forces. The list is not exhaustive:
♦Telecommunications companies have purchased land mobile and transportable MTs
for operating and maintaining land lines, both fiber optic and wire. Mitsubishi MTs
can improve the efficiency of field units responding to fiber optic cable failure, saving
a lot of money. These companies typically use dispatch service.
♦Oil and gas companies use land mobile MTs for regular pipeline maintenance
operations. Maintenance trucks testing pressures and physical integrity throughout
the extent of a pipeline or segment of pipeline can remain in constant
communications. This concept is very similar to that employed in the
telecommunication industry.
♦Mining and construction companies can more effectively conduct day-to-day
business from even the most remote locations. Their business may require continuous
communications with other remote sites, fleets on the road, and headquarters through
the PSTN. Day-to-day business may just entail a report at the end of each day—
either voice or data.
♦Any large corporation in regions prone to natural disasters, like the West Coast or
Gulf States, can use MTs for contingency communications. This application is not
the same as back-up communications for conducting business operations. Rather,
contingency communications link key executives and decision-makers for
implementing already existing recovery and response plans.
♦Hospitals, nuclear facilities, and HAZMAT trucks require some form of
emergency communications for public safety reasons. Dedicated channels or high
availability channels can save lives during emergency situations that can disable or
degrade the existing terrestrial infrastructure. As a simple example, any cellular
telephone user in a major metropolitan area knows that even a minor traffic accident
on a commuter route can saturate capacity as hurried drivers begin making calls.
More severe emergencies exponentially degrade consumer-type systems.
