Introduction

The W61SAT Option allows the monitoring of the L-band downlink in the 1550 MHz range - the forward path - of the INMARSAT System. This link contains the traffic from the Land Earth Station, LES to the Mobile Earth Stations, MES. 'EasySatSystem' is an application that manages the satellite decoding modes running on a system of up to 10 W61PC cards to prevent that more than one W61PC card monitors the same satellite communication session, identified by a specific satellite mode (INMARSAT-B, INMARSAT-M, INMARSAT-mini-M and INMARSAT-C), a service (data, fax, ISDN, etc.), and mobile earth station identification number (termed MES Id in the following). The monitoring system configuration is specified in a text file using a very simple syntax. For logging purposes, statistical data concerning the monitored sessions can be collected. 'EasySatSystem' has three kinds of user interfaces: the operational status display of the coordinated cards, i.e., the EasySatSystem graphical user interface (GUI) the configuration interface, i.e., the text file EasySATSystem.ini, stored in same predefined directory

PCs with W61 cards and W61SAT Option

coax signal cable

The monitoring system consists of three main components: An antenna, including a low noise amplifier (LNA) 2 Description of the System
A down converter One or more W61PC card(s) with W61SAT options One or more card hosts These components are connected with coax cable. If more than one W61 is to be fed from the same source, a splitter must be used to correctly match the input impedance of the W61 70-MHz input (input IF70#4, Zo = 50 Ohm).

Antenna/LNA

The antenna system must have a figure of merit G/T > 0 dB/K. This can be easily achieved with a parabolic dish with a diameter of at least 2 m and a low noise amplifier with a noise figure smaller than 0.8 dB. The polarization of the L-Band signal is RHCP (Right-Hand Circular polarization), so if a parabolic reflector is used, the feed must pick up the mirrored left-hand (LHCP) component. Tracking of the satellite for this diameter of the dish is not necessary, and if so desired the antenna can be of a fixed type, which is installed and aligned to the satellite only once. The power of Inmarsat spot beams allow antennas for terminals to be quite small, but for monitoring purposes larger antennas are required in order to also capture neighboring spot beams. WAVECOM recommends a dish of at least 2.4 m diameter.

Down converter

The down converter is a commercially available product, converting L-band to 70 MHz IF with a bandwidth of +/- 20 MHz. Required SNR before decoder: >15 dB (20 dB recommended)

PC(s) with W61PC(s)

These are state of the art computers, running under Microsoft XP, Vista, Windows 7 or Server 2008 with the same number of PCI slots as the number of W61 cards to be installed. We recommend 4 cards/PC if cooling and power supply are appropriate. Proven Components Check our application note AN-INMARSAT Setup.

Installation

During the installation of the EasySatSystem application by means of the setup utility provided, the directory into which the application is installed can be specified. In the text of this document the directory will be called <easysatsystem_dir>. The following files exist in <easysatsystem_dir>: EasySatSystem.exe (the executable) XMLRCICPP.dll (a required DLL) EasySATSystemUserManual.pdf (this document) FileHandler.exe (a program solely needed during the installation of EasySatSystem) WAVECOM_Decoder.chm (the help file) Administrator privileges are required to modify the contents of the <easysatsystem_dir> directory The configuration file of the application is stored in a subdirectory to <easysatsystem_config_dir>, e.g. C:\Documents and Settings\All Users\Documents\WAVECOM \EasySATSystem\Config. This directory contains these files:

Software 3

EasySatSystem.ini Template-EasySatSystem.ini By default, after start of EasySATSystem.exe, the program looks in this <easysatsystem_config_dir> directory for the required configuration file EasySATSystem.ini. However, a different directory can be specified by setting the environment variable EASYSATSYSTEM_CONFIG_DIR accordingly. The data captured by the decoders will be stored in a subdirectory referred to as <easysatsystem_data_dir>): C:\Documents and Settings\All Users\Documents\WAVECOM\W61PC\Data-Output\Inmarsat[Card SN] By default, the <easysatsystem_data_dir> directory will be used to store statistical data files (if logging has been enabled, see below). Again, a different directory can be specified by setting the environment variable EASYSATSYSTEM_DATA_DIR accordingly. User privileges are sufficient to modify including delete the subdirectories \Config and \Data as well as their respective contents. In order to have EasySatSystem working properly, the 'XML Remote Control Interface' port has to be opened on each PC hosting managed W61PC cards. This is done as follows: 1. Open Control Panel 2. Open Windows Firewall 3. If the On button is set, then clear the Don't allow exceptions checkbox 4. Select the Exceptions tab 5. Click on Add Port and give a name and set the port number to the default value of 33234, or to the value you have specified in the tab Networking Information of the W61PC WavecomServerControl GUI 6. For test purposes, it might also be necessary to open the port for the GUI of W61PC (default value of 33233) Furthermore, on each PC hosting W61PC cards to be coordinated, the respective WavecomService must be running and allow remote connections. In order to allow remote connections to a WavecomService, check the box Allow Remote Connections in the tab Networking Information of the respective W61PC WavecomServerControl GUI.
'EasySatSystem' can run on any PC under the Microsoft Windows XP, Vista or Windows 7 operating system. If cards on more than one PC must be coordinated, then the PCs must be connected via a network. 'EasySatSystem' must be told somehow which PCs hosting which W61PC cards it must coordinate. This is done with the configuration file EasySATSystem.ini, which, by default, needs to be located in the directory <easysatsystem_config_dir>. An alternative location can be specified by means of the environment variable EASYSATSYSTEM_CONFIG_DIR.

4 Software

In the EasySATSystem.ini file, one can also specify the sessions to exclusively be watched by listing the respective MES Ids; if no MES Id is specified, then all sessions will be watched. It is also possible to specify the duration (in seconds) of the automatic level setting (ALS) performed at mode start-up. Only the first valid value specified will be used, if several are given in EasySATSystem.ini. If desired, EasySatSystem collects statistical data concerning the monitored sessions. In such a case, when exiting EasySatSystem, a text file is stored in the directory <easysatsystem_data_dir> or in the directory specified by the environment variable EASYSATSYSTEM_DATA_DIR if it is set. The name of such a file is Stat<dateAndTime>.txt, where <dateAndTime> denotes the date and time (including seconds) of the log-file creation, which occurs at the end of a monitoring session with EasySatSystem. Be aware that such a file may become quite large. To enable statistical logging a sampling interval (in seconds) greater than 0 has to be specified in EasySATSystem.ini. Only the first valid value specified will be used, if several are given in EasySATSystem.ini. The name of the configuration file must be 'EasySATSystem.ini' (case-insensitive). Below, the syntax of the configuration file is specified, for which the following rules apply: Whitespace (blanks, tabs) can be expanded to any length EOL means end-of-line means repetition 0 or more times Single superscript (e.g., xyz10) means repetition exactly the given number of times Range superscript (e.g., xyz1-9) means repetition with minimum and maximum bounds Bold words must appear exactly as shown | means alternative Terms in <> are expanded The starting point for the syntax is <config>.

Note: The string <nameOrIPAddress> can be the PC name, or the dotted IP address of the PC. The local PC of 'EasySatSystem' can also be denoted by 127.0.0.1 A maximum of 10 card-sections can be specified. Each card can run on its own PC, so there can be a maximum of 10 PCs. One PC can have a maximum of 8 cards The number of MES Id watch-sections is not limited Following are two examples of valid configuration files. Example 1 shows the configuration file for a system with 4 cards configured for INMARSAT-B, 1 for INMARSAT-M and 5 for INMARSAT-mini-M, residing on 2 different PCs (Niklaus2 and Test-w61pc). All MES Ids shall be considered, no ALS shall be performed, and no statistical data shall be collected. In Example 2, the system to be monitored consists of 3 different PCs and 4 cards: The local one (127.0.0.1) with one card and two remote hosts, 123.45.67.89 with one card and ComputerA with two cards. On all cards INMARSAT-B transmissions with specific MES Ids shall be monitored. Furthermore, ALS shall be performed for a period of 5 minutes (300 seconds), and statistical data shall be collected every 30 seconds.

The rules must be followed strictly; if there is an error in the EasySATSystem.ini file, the corresponding card will not be included in the coordination process.

Software 7

Operation
'EasySatSystem' must be started by the user. The command to start EasySatSystem has the following format: <easysatsystem_dir>/EasySatSystem [/L:<n1>] [/A:<n2>] The optional argument /L indicates that statistics data should be collected. The number <n1> must be in the range 4.120. This number specifies the sampling interval for the statistics data in seconds; (approximately) every n1 seconds a snapshot of the busy status of each card is taken and written at program termination to the statistics file Stat<dateAndTime>.txt in <easysatsystem_data_dir> or in the directory specified by the environment variable EASYSATSYSTEM_DATA_DIR if it is set. If this argument is not present, or n1 is not in the range 4.120, no statistics data will be collected. A sampling interval specified in the configuration file EasySATSystem.ini has precedence over the value passed as argument on the command line. Absence of both parameters indicates that no statistical data has to be collected. The optional argument /A specifies the duration (in seconds) of the ALS that will be performed on each card. An ALS period specified in the configuration file EasySATSystem.ini has precedence over the value passed as argument on the command line. Absence of both parameters indicates that no ALS has to be done. After starting EasySatSystem, a new window appears on the display, showing one line of status information for each correctly configured W61PC card, as well as the specified ALS period, sampling interval, and MES Id watch-list. The maximum number of cards is fixed to maxN=10, since the window has space for exactly this number. If less than maxN cards are configured, the remaining lines contain empty fields. For each configured card the following information is shown: Column heading

Number SAT Mode Computer Name or IP Address Serial # Op Status

meaning

This is the global number of the card within the scope of the coordinated cards; range: 1.maxN The SAT mode configured on this card Address of the PC containing this card; can be the (dotted) IP address or the computer name; maximum length 30 characters Serial number of this card Operational status of the card, this can be: 'Not Connected': the PC containing this card is not under control of EasySatSystem 'Host Connected' (transient): the PC has answered to EasySatSystem and announced all its cards 'Card Ready' (transient): the card has answered 'Mode Running': the mode was set on the card 'Busy Session': the card is monitoring a SAT session If Op Status is ' Busy Session', this is the forward MES Id of the terminal being in the monitoring session, otherwise this field is empty; If Op Status is ' Busy Session', this is the service being monitored, otherwise this field is empty

MESId Service

The term transient means that this state may last only a very short time, and is therefore possibly not visible for the user. If a configured card is not shown at all, then there must be an error in the respective cards specification in the EasySATSystem.ini file. There is only one button available, labeled Exit. Pressing this button will terminate the program, as will pressing the Close button in the window frame. Note: At start-up, 'EasySatSystem' does not automatically synchronize with the operational status of the cards, meaning that, if a card is already in a session, this is not shown. Only at the next status change of the card, the Op Status field will display the correct status It can take some time until the program has properly terminated after pressing Exit or Close The system does not check if more than one instance of 'EasySatSystem' is coordinating the same card(s). So make sure to start this program with the same cards configured only once It is recommended to manually control from time to time the signal level settings at the different cards under the control of EasySatSystem, also when ALS is enabled

8 Software

Error Handling
'EasySatSystem' tries to connect configured, but not connected cards approximately every 30 seconds. All cards not connected are shown in the Op Status field accordingly.

Functions

General The easy-to-use graphical user interface (GUI) with well structured pull-down menus allows an operator to become familiar with the W61PC in a short time. A high degree of operator proficiency can quickly be achieved. The decoder can be used in a number of configurations: Local use as a PC application Remote use via a LAN with standard W61PC application instances in a client-server mode Remote control using TCP/IP and XML Remote use with a Remote Desktop connection These features allow the system to be adapted to the client's requirements and applications. The implementation of complex systems for monitoring on a large scale is only limited by the number of decoders and the performance of the hardware and software. Analysis The determination of signal characteristics is assisted by a large number of analysis and measurement functions operating over a wide range of signal parameters. All of the integrated analysis tools contain many different methods and viewing options. The GUI assists the operator in analyzing the important signal parameters. Exact measurements are easily made using adjustable cursors with associated numerical displays. Dynamic zoom functions allow magnification of details in any selected window. The scroll buffering feature makes it possible to move back and forward in signal history. Spectrum (FFT/Sonagram) The configuration of the system components can be completely adapted to the requirements of the customer. A wide range of system default settings can be configured, e.g., input signal level, measuring interval, centre frequency and demodulator type. A W61PC decoder may be controlled from everywhere in the network and its output may be sent to one or more applications on the network. In order to process the data output, control the decoder and the code parameters, an integrated remote control interface allows easy control of the W61PC from a customer application.

W61CL Classification (Option)
The ability to rapidly identify unknown signals has become an essential requirement in signal analysis.

Spectrum display

In this pane the monitored frequency spectrum is displayed. After classification has completed the classified signals are indicated in the spectrum display.

Classification

The results of the classification are shown as a list in a second pane. The following parameters are provided for each classified signal: Spectrum, Classifier and Code-Check Windows The automation of the signal classification process relieves the operator from manual evaluation, which otherwise requires considerable skills and experience. The combination of a classifier and a decoder thus satisfies the requirement for an automatic system that is able to rapidly and reliably determine the characteristics of radio data transmissions within the signal spectrum being monitored. The classification algorithm determines the accurate center frequency, speed (symbol rate), shift, bandwidth and modulation. The detection and classification results are displayed in a list together with all parameters and are fully integrated into the WAVECOM user interface. Modulation type Center frequency of the signal Number of carriers in the case of multi-carrier FSK Baud rate in the case of FSK or PSK signal Frequency shift in the case of FSK signal Bandwidth

Additional information

Additional graphical FSK, MFSK and PSK information on symbol timing and constellation, baud rate and frequency vs. time is displayed in a separate window when a classified signal is selected from the list.
Classifier-Code-Check (CCC)

An FSK/PSK or MFSK code check of the classified signal is started to further determine the protocol of the signal. After the code check has completed, the classifier and code-check results are used to automatically parameterize the code and start decoding.

W61SAT (INMARSAT Option)

The W61PC-SAT, together with the W61PC hardware is the first choice to build a cost efficient satellite monitoring system for INMARSAT. The user interface of the WAVECOM satellite modes is fully integrated as a software module in the existing hardware and professional software. Additional functions are: Remote Control, to enable the customer to build his own customized system. INMARSAT B/M/mM, L-Band only, forward channel monitoring (does not require a large C-Band antenna).

INMARSAT B-HSD

HSD (High Speed Data) Service using Inmarsat-B enables high-speed data communications between an INMARSAT terminal and a land-side ISDN terminal or between two Inmarsat terminals via 64 (56) kbps or 128 (112) kbps circuit.

INMARSAT B/M/mM

These modes offer video, data and fax service at different speeds. The software monitors the control channel, and upon initiation of a new session with a mobile terminal, automatically switches to the assigned traffic channel for monitoring.
Sat Dishes for monitoring

INMARSAT C-TDM

INMARSAT C is a store-and-forward, low speed message transmission system. Currently it is one of the most reliable and most used systems for today's communication. This is traffic going to the MES. Data output is in ASCII, HEX or Baudot.
Satellite locations To limit the volume of monitored traffic, a watch list may be created containing target MES IDs. Monitored fax and data sessions are stored in files. A fax viewer is included in the software. INMARSAT B and M Voice are supported (mM on request).

INMARSAT B-C-TFC

SAT-B-C-TFC is used to monitor the return signal of SATB. This signal can be the uplink L-Band signal, or the downlink C-Band signal. INMARSAT C-TDM traffic

INMARSAT-C-TDM-EGC

The INMARSAT C maritime mobile satellite system has an inherent capability, known as Enhanced Group Call (EGC), which allows broadcast messages to be made to selected groups of ship stations located anywhere within a satellite's coverage. Four geostationary satellites provide worldwide coverage for these types of broadcasts. Two types of EGC services are available: Safety NET and Fleet NET.
