Somewhere about 36,000 km are very far in the geocentric orbit remote from Earth at distance, there are satellites sending us the signals containing the most various data. That these signals turned on screens of monitors into the video image, a sound and other data representation forms, it is necessary to install the satellite antenna and to direct it precisely to the satellite transponder. It is possible to make it only if the direction in which there is the last is known.
It is required to you
- – computer with the satellite equipment;
- – GPS navigator (not necessarily);
- – a satfaynder – the device for setup of the antenna for the satellite – it is also not obligatory.
Instruction
1. Before setup of the antenna for the satellite at you the satellite equipment (the network interface card, the antenna, the converter) has to be mounted and the software for the card is installed. Visit the website http://www.lyngsat.com and find there the satellite on which you need to define the direction. Open the page with parameters of transponders of this satellite. Check according to the coverage map whether there is your area in an area of coverage of the signal interesting you. If yes, that you write out its parameters (symbolical speed, FEC coefficient, polarization, frequency).
2. Start the program tuner of the network interface card in the computer, enter into it the received values of parameters and press the scanning button. If absolutely accidentally your antenna was not precisely oriented on the satellite, the program has to show lack of a signal – red light on the graphic indicator and lack of a sound.
3. Determine coordinates of your location. It can be done by means of the GPS navigator, according to the map or having used one of online services by determination of geographical coordinates. For example, here: http://api.yandex.ru/maps/tools/getlonglat/. Coordinates on this website are given in the form of decimal fraction. To transfer them to degrees, minutes and seconds, use a website http://www.neolite.ru/coord_converter.html online service. Having entered decimal values of coordinates, carry out their converting in degrees with minutes and seconds.
4. Install the program for definition of the direction on the SAA satellites (Satellite Antenna Alignmen) and start it. In the opened window find yours in the list of satellites and click on it. In a window coordinates of positioning of the satellite have to appear on the right. If there is no necessary satellite in the list, enter its coordinates manually. Enter the coordinates of an installation site of the antenna determined in the previous step slightly below.
5. In response to data input the SAA program will give values of an azimuth and an angle of lead of the satellite over the horizon. Go to the Azimuth in the Sun tab and define time when the sun is in the same situation on an azimuth, as the satellite (time of a solar azimuth). Go to the Offset Antenna tab and define an antenna angle of lead.
6. Orient the antenna in the situation corresponding to the received parameters (azimuth and an angle of lead of the antenna). Having used a satfaynder (the device for search and definition of satellites), carry out exact guidance of the antenna on the satellite. The device has to record a signal. Achieve its maximum force and fix the antenna by bolts.
7. In the absence of a satfaynder execute exact targeting by means of the program tuner – displacing the antenna in different situation and watching the program indicator. When existence of a signal is recorded, achieve small shifts of its maximum and enshrine the antenna in this provision by bolts.
