[. . . ] 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". Software 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: WAVECOM EasySat System Software V1. 2 User Manual 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. If the On button is set, then clear the "Don't allow exceptions" checkbox 4. 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. Setup '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. [. . . ] 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 WAVECOM EasySat System Software V1. 2 User Manual 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.
