SM67 Rev. 4.10 STX100-000 Globalstar™ Satphone Transceiver Manual

Section 1 Description

1.1 Introduction

This manual contains information on the STX100-000 Globalstar™ Satphone
Transceiver. All derivative products will be covered by manual supplements, which can
be obtained from NAT as required.

Information in this section consists of purpose of equipment, features and specifications.

Note: The STX100-000 is shipped from NAT in a deactivated state. The unit must be

registered with and activated by Globalstar
can be attempted. Please refer to the information sheet packaged with the
STX100-000 for registration details.

1.2 Purpose of Equipment

™ before any operation of the system

The STX100-000 is a complete, self-contained airborne Satphone Transceiver for use
on the Globalstar

™ satellite communications system. The system is voice and data

capable (single channel), and is designed for use with the PTA12 POTS Telephone
Adapter and the LMC01 Latitude Mobile Controller, both manufactured by NAT Ltd.

The LMC01 is used to provide asset management and positioning capability (e.g., flight
following). The LMC01 is a remote mounted unit, and connects to the data port on the
STX100-000. The LMC01 is optional, and is set-up at time of installation to operate
automatically. Refer to the LMC/LMC01 Users Manual for more information.

The voice connection is made with a standard two-wire connection (tip/ring). This is also
referred to as a POTS (Plain Old Telephone Service) interface and is the audio path
to/from the PTA12. This will also allow connection of a standard, 2-wire handset for
cabin purposes, if needed.

Note: Due to current limitations (30 mA) on the POTS interface, the handset should be

powered from the aircraft to ensure proper operation of the system.

The data connection is through the STX100-000's data port. The data port supports
asynchronous and packet data services. Asynchronous data services allow for the
transmission of ASCII or binary data between a computer or other device connected to
the STX100-000 and any Hayes™ compatible modem connected to the Public Switched
Telephone Network (PSTN). Packet data services allow for the connection of a device
able to support a PPP session using TCP/IP. This is the typical standard used by
computers for dial-up service.

2.3 Installation Procedures

2.3.1 Warnings

Do not bundle any lines from this unit with transmitter coax lines. Do not bundle any
logic, audio, or DC power lines from this unit with 400 Hz synchro wiring or AC power
lines. Do not position this unit next to any device with a strong alternating magnetic field
such as an inverter or significant interference to operation will result. In all installations,
use shielded cable exactly as shown

and ground as indicated. Significant problems

may result if these guidelines are not followed.

2.3.2 Cautions

All audio installations can be severely degraded by incorrect wiring and shielding, and
may result in much higher cross-talk, hum, and ground-loop interference. This should
be considered when audio wiring to and from the radio system installation is performed.

In communication intensive applications, poor cable routing and shielding may drastically
compromise over-all system performance. Use caution in the routing of wire bundles.

The STX100-000 can be connected to and used with a 2-wire handset, however the
handset current must not exceed 30 mA due to restrictions in the loop current available
from the 2-wire POTS interface in the STX100-000. The handset should be powered
from the aircraft’s electrical buss to ensure proper operation of the satphone system.

2.3.3 Notes

The case of the STX100-000 must be electrically grounded for maximum resistance to
low frequency interference. Pin 16

(CHASSIS GROUND) on connector P103 is provided

and must be connected by a short wire to a clean ground, not jumpered to the power
ground wire connection.

2.3.4 Cable and Wiring

All unshielded wire shall be selected in accordance with AC43.13-1B Change 1,
Paragraphs 11-76 through 11-78. Wire types should be to MIL-W-22759 as specified in
AC43.13-1B Change 1, Paragraphs 11-85, 11-86, and listed in Table 11-11. For
shielded wire applications, use Tefzel MIL-C-27500 shielded wire with solder sleeves
(for shield terminations) to make the most compact and easily terminated interconnect.
Follow the wiring diagrams in Section 2.7 as required.

All wiring should be 22 AWG minimum, except power and ground connections, which
must be 18 AWG or larger, as indicated on the installation drawings. Ensure that the
ground connection is clean and well secured. To prevent inadvertent system failure,
power to this system must be supplied from a separate breaker or fuse and not
connected to any other device. A 5 A fuse or breaker is recommended (28 Vdc).

Allow 3 inches from the end of the wire to the shield termination to allow the hood to be
easily installed. Note that the hood is installed after the wiring is complete.

CONFIDENTIAL AND PROPRIETARY TO NORTHERN AIRBORNE TECHNOLOGY LTD.

SM67 Rev. 4.10 STX100-000 Globalstar™ Satphone Transceiver Manual

Fabrication & installation of wiring harness should be in accordance with AC 43.13-1B,
chapter 11, sections 5-12.

Grounding and bonding should be in accordance with AC 43.13-1B, chapter 11, section 15.

2.3.4.1 Coaxial Cables

The RF budget for the STX100-000 is very specific for both the RX and TX paths. The
type and length of coaxial cable is critical in order to achieve proper performance of the
STX100-000 system. It is recommended that the coaxial cables be sourced from a
vendor that specializes in the fabrication of low loss cable sets. Refer to Tables 2-1 and
2-2 for examples.

Coaxial cable should be in accordance with MIL-C-17 unless otherwise specified. Do
not use coax with PVC insulation. Teflon dielectric cable is recommended at or above
UHF frequencies or where cable runs exceed 8 feet. Note that at these frequencies, cable
losses due to long cable runs and tight bends may cut the ERP (Equivalent Radiated
Power) to less than 50% of specification.

RF cables must be neatly terminated (solder or crimp), and tested for shorts prior to system
check-out (not while connected to the radio or antenna). Keep cable bends to a minimum
at the antenna. Avoid sharp bends in the coax cables to prevent severe reflections. If
sharp bends are required, use 90° elbow adapters.

When routing the coaxial cables make sure they are properly identified as they use the
same connector for both the RX and TX connections at the STX100-000. This can also be
true of the antenna, depending on the model used for the installation.

2.3.4.2 Cable Lengths

The transmit and receive coaxial cables and TX Filter have a minimum and maximum
signal loss that must be taken into consideration. Exceeding the min/max signal
strength by having an improper coax length may cause poor system performance. For
reference, the calculations are based on a transmit frequency of 1.6 GHz, and a receive
frequency of 2.5 GHz.

Transmitter path loss (min): 1.35 dB * Receiver path loss (min): 1.50 dB
Transmitter path loss (max): 2.15 dB ** Receiver path loss (max): 8.50 dB

* Includes the transmitter filter insertion loss (nom) of 1.8 dB.
** Includes the transmitter filter insertion loss (max) of 2.0 dB.

The tables below identify examples of coax cable types that can be used and shows the
min/max cable lengths for that type. The calculations take into consideration the losses
associated with the transmitter filter (transmit cable only) but they do not take into
consideration the losses associated with the coaxial connectors. Any other quality coax
cable can be used provided it meets the requirements for min/max cable loss.

2.3.5 Antennas

Correct antenna placement and mounting is critical in order to achieve the best possible
performance. In general, keep all antennas as widely separated as possible and clear
of any large airframe obstructions.

Installation of the antenna should be in accordance with AC 43.13-1B, chapter 4,
section 4, and AC 43.13-2A chapter 3. If possible, the antenna should be located a
minimum of 8 feet from aircraft navigation receiver antennas and a minimum of 4 feet
from aircraft communications and ELT antennas.

Note: The STX100-000 antenna should be located a minimum of 6’ from the GPS

antenna, and MUST be top mounted (satellite view).

Avoid antenna locations that may become fouled with oil, water, fuel or dirt, as this will
degrade performance.

CAUTION:

Ensure that the unit is mounted in a location where the general population will
not approach within 8 inches (20cm) of the transmitting antenna. This distance
provides an additional safety margin for the product.

SM67 Rev. 4.10 STX100-000 Globalstar™ Satphone Transceiver Manual

2.3.6 Mechanical Mounting

The STX100-000 is a tray-mounted device and uses a standard 1/4 ATR style tray.
Mount (with counter-sunk screws) onto a clean, grounded surface having a resistance
of less than 0.5 ohms to airframe ground. The STX100-000 may be mounted in any
attitude, but upright (mounting hook at the bottom) is preferred for access and
condensation drainage.

The TX Filter Assembly should be mounted in close proximity to the STX100-000. The TX
Filter is supplied as part of the STX100-IKC install kit, which also includes the base plate
and associated hardware that can be used to provide a convenient method of mounting
the TX Filter. The TX Filter (with base plate attached) is secured with four 10-32 screws.

Installation of the STX100-000, its mounting tray, and the TX Filter should be in
accordance with AC 43.13-1B, chapter 4, section 4, and AC 43.13-2A, chapter 2. Ensure
adequate space is available to allow airflow around the STX100-000 unit.

2.3.7 Data Port

The Data Port allows the user to connect a computer to the STX100-000 to access data
services. There are 2 types of data services handled by the Data Port: Asynchronous,
and Packet Data. For both of these services, the equipment interfacing to the STX100­000 must be configured for 19200-baud, 8 bits, 1 stop bit, no parity, and hardware
handshaking, with EIA/TIA RS-232 standard signal levels.

Note: The STX100-000 is shipped from NAT in a deactivated state. The unit must be

registered with and activated by Globalstar™ before the following tests can be
conducted. Please refer to the information sheet packaged with the STX100-000
for registration details.

2.3.7.1 Asynchronous Services

Asynchronous Services establishes a data connection between a computer or other
device connected to the data port, and any Hayes compatible modem that is connected
to the Public Switched Telephone Network. The connection between the device and the
remote modem is accomplished by dialing the number of the remote modem from the
AT command line (i.e. ATD18883359533 <ENTER>). Once the connection is
established between the 2 modems, binary data, or ASCII data can be transmitted.
Sending the "+++" followed by a delay of longer than 1 second, followed by "ATH"
terminates the connection.

2.3.7.2 Packet Services

The data connection is established by the computer issuing a dialing command
"ATD#777<enter>". This starts a PPP session using the TCP/IP protocol. Sending the
"+++" followed by a delay of longer than 1 second, followed by "ATH" terminates the
connection.

d) Request the ‘called party’ to place a call to the aircraft, and confirm ringer

operation and incoming call functions.

2.3.8.3 Power On Checks, Data

a) Following completion of the Voice tests, connect a laptop computer to the data

port on the STX100-000 (this assumes the data port connections are accessible
and allow for easy connection to the laptop).

b) Using a terminal emulator program (i.e. HyperTerminal, TerraTerm, etc.) with the

serial port correctly set to communicate with the STX100-000 (19,200 baud, 8
Bit, 1 Stop Bit, No Parity), type AT <Enter>. You should get an OK back from the
STX100-000, verifying the data port wiring is correct and that you can
communicate with the internal modem of the STX100-000.

Once you have verified connection with the modem, you can test the PPP connection
using TCP/IP. Confirm you have correctly set the modem and dial-up networking
connections, and that you have a working ISP before proceeding with the test.

1.0 Introduction

The purpose of this test is to identify any interference that the STX100-000 Globalstar™
Satphone Transceiver may cause with existing aircraft systems.

1.1 Test Conditions

The STX100-000 should be installed and function tested in accordance with the
STX100-000 Globalstar™ Satphone Transceiver Installation and Operation manual.

1.2 Methodology

Most of the EMI tests can be accomplished on the ground. In some cases, flight-testing is
required or is easier. If the aircraft is approved for IFR operations, then it is mandatory
that interference between the STX100-000 and the approach aids be checked in flight.

The GPS should be operational and navigating with at least the minimum complement of
satellites. VOR/ILS/GS receivers should be set to the test frequencies and selected for
display. If possible, set up a VOR/ILS ramp test set on the test frequencies and adjust the
output until the flags are out of view. The transponder and encoder should be monitored with
ramp test equipment. If possible set the ADF to a nearby navigation station.

Modulate the STX100-000 transmitter for at least 20 seconds. Observe the GPS for any
degradation in satellite status or availability or flags. Listen for any noise or detected
audio signals on the VHF comm(s). Listen for any noise or detected audio signals on
the VOR/LOC receiver audio; look for any movement of flags or needles on the
VOR/LOC/GS navigation display(s).

Monitor the power plant, fuel and other electric instruments in the chart provided and
note any anomalies that occur while operating the STX100-000. Assess the results.

If the aircraft is equipped with an Automatic Flight Control or Stability Augmentation
System, test fly the aircraft and verify that the operation of the STX100-000 Satphone
Transceiver does not have adverse effects on these systems. After checking for gross
effects at a safe altitude, fly an approach with each of the different navigation systems
coupled to the autopilot (ILS, GPS etc.) and look for any anomalies.

the appropriate standards of airworthiness for the system in question. For example: it is
permissible for a VFR certified GPS to lose navigation capability while the STX100-000
is transmitting, providing that it recovers properly and promptly, but it is not permissible
for an IFR Approach certified GPS to be affected in the same way. A complete
discussion of all the standards of airworthiness to be applied in assessing EMI effects is
beyond the scope of this document.

STX100-000 Installation Approval Test Procedure

3.0 GROUND FUNCTION TEST SPECIFICATION - EMI/RFI Testing

3.1 Scope

This document provides guidance for conducting ground procedures and EMI/RFI
testing of an aircraft’s added or removed electrical equipment.

3.2 Acceptance Criteria

While performing testing, the systems under test (i.e. the added equipment) are
considered to have passed if the aircraft instrument and data displays and/or equipment
operate normally and NO failing criteria, as described below, are witnessed.

The System Under Test (SUT) passes if the existing aircraft system only indicates a
momentary flicker or slight movement of the display, as long as the movement is not a
permanent displacement.

The SUT passes if evidence of interference can be determined only by an audible
change of aircraft speaker and/or headsets and the change exhibits a ‘pop’ or other
transitory noise when the SUT is operated in its various modes.

The SUT passes from the standpoint of Automatic Flight Control and Stability
Augmentation System equipment if the SUT does not cause a detectable response from
these flight control systems.

3.3 Ground Test Procedures

All tests may be performed using an external power source, or during a ground engine
run with all electrical systems on line and operating normally.

With the equipment power connectors disconnected, apply ground power and
energize the circuit breakers.

Using the wiring diagram, verify the voltage (power in, and ground) at each of the added
components’ power and ground terminals. Determine, record and correct all
discrepancies before continuing.

Note: During the next step observe the aircraft electrical load meter and verify that it

stays within safe operating range and does not exceed the aircraft’s electrical
generating capacity.

Energize the individual items of the system being installed, one at a time, and apply
power to each. Ensure that each system is operating correctly, referring to equipment
installation and operation manuals for correct operation procedures.
