Advice 1: How to see satellite

If in the evening or morning twilight in clear weather to go out, there is a very high likelihood that soon you will see in the sky one of the many artificial satellites.
International space station visible in night sky with the naked eye

Currently, the number of running earth's orbit of the satellites is about 35,000. Most of these objects - nothing more than space debris, ranging in size from soccer ball to one meter in diameter.

Most satellites cannot be seen with the naked eye. But hundreds of them can be seen. Satellites are large enough - from 600 metres in length and located at a fairly low altitude, from 1400 to 8400 feet above the surface of the Earth.

You can see them provided that they reflect the sunlight.

The largest artificial satellite of the Earth

The international space station (ISS) - the largest artificial satellite in earth orbit. The construction of the station began in 1998. Its size is four times exceed the dimensions of a no longer existing station "Mir".

The ISS rotates around the earth's orbit at the altitude of 348 km and at a speed of 27700 km per hour. Space station makes around the Earth 15.7 turnover for the day. It can be taken for fast flying plane, crossing the sky for about 4-5 minutes.

Due to its large size and panels, well reflecting the sunlight, the international space station is the brightest man-made object to orbit the planet.

Under favorable conditions, the plant would glow as brightly as the planet Venus and is 16 times stronger than the brightest night star, Sirius.

Other possibilities

In addition to ISS, you can search for the eyes of the Shuttle. Also see with the naked eye in Earth orbit space telescope "Hubble".

When is the best time to observe satellites

The best time of the year to monitor the satellites in June and July. In these months, the nights shortest, and the Sun will take longer to illuminate objects in the sky. In other months you will not see this.

In addition, because the ISS is in relation to the equator at an angle of 51.6 degrees, you can see two different trajectories of its motion across the sky.

At first the station appears in the southwest part of the sky and rushes to the North-East. After seven or eight hours, you can see a very different movement: the satellite rises in the Northwest and goes beyond the horizon in the South-East.

Best watch for monitoring orbital station - 45-60 minutes after sunset and 40-60 minutes before sunrise.

Advice 2: How to see ISS from Earth

The international space station is the brainchild of many countries, space house near the Ground. It is growing, it added new modules, and the ISS can already be seen from Earth with the naked eye. If you set out to see the ISS from Earth, remember that nothing is impossible. This station is not only seen but also photographed people from different countries across the roof of his house. These tips will help you to realize your dream and see the international space station with my own eyes.
How to see ISS from Earth
You will need
  • - computer with Internet access;
  • - dark night sky without clouds.
Instruction
1
To begin, note that the station can be seen when it is illuminated, and the Earth (i.e. you), are in the shade. Also, choose a time when the station is on your side of the equator and the sky is covered with clouds.
2
To find out where the ISS currently, download software http://www.heavensat.ru/#links-extract and install to your computer. However, no file with information about the satellites orbits and the parameters of stars good program, so on the same page, take the archive ""SKY2000" Master Catalog, Version" and paste it in the program folder ("StarCatalogs").
3
Then download the folder with the parameters of the orbits of artificial satellites of the Earth on the websites СelesTrak.com or www.space-track.org will put it in a folder Tle in the Heavensat directory.
4
Run the program and locate the directory of the ISS, where it is called the ISS(ZARYA). Click on the tab "Earth", right click "Base satellite". Then, select the Tle file that you first downloaded (in the left). You will see all the satellites, which have information in your database.
5
Turn on the real time ("Now"), you will see how and in what direction we are moving different satellites. Look to the right of the box "source satellite" and click "custom", enter in the upper field ISS, which will result in a line ISS(ZARYA). In the other tabs, set your coordinates to see if the station is flying past you at this point.
6
Now you know where flies the ISS in a given time, and to know where it is, for example, in an hour, use the simulation mode.
7
If you did everything right, but something did not work, you can try the next option. Go to the site of mission control Center http://www.mcc.rsa.ru/trassa.htm. Here view the trajectory of the International space station in real-time.
8
Another option is the trajectory of the ISS based on Google Maps http://www.lizard-tail.com/isana/tracking/ here view the height of the station above Ground, speed, current coordinates. If you have time, and you are lucky enough, will have time to see your home from outer space.
Useful advice
In order to photograph the ISS, it is necessary to prepare in advance and stock up on very good technique, time of visibility of the station from one place usually does not exceed several minutes.

Advice 3: How to configure satellite Sirius

System satellite TV is a complex equipment that performs reception of television programmes, broadcasting of which is made using a special communication satellites located above the equator in geostationary orbit.
How to configure satellite Sirius
You will need
  • antenna;
  • receiver;
  • TV.
Instruction
1
Install the wall mount the antenna on a vertical surface at an angle is strictly 90 degrees. Secure all points provided by bolts. Install a Central Converter and multifidi on the Central arc of the antenna. First, set up a multifeed. On the arc of the antenna put on the mounting strip, pull loose her bolt-nut. Install the Converter and turn it on 100 counterclockwise (1 step = 5 degrees).
2
To configure the antenna for the Sirius install for the arc center of the third Converter, rotate it to 10-15 degrees. Tighten all fasteners completely. Prepare three pieces of wire a small length, strip them, screw the F-connectors, connect them to the Converter, fit the protective covers. Install the antenna on the wall mount. For the possibility of its rotation, tighten the retaining nut until the end.
3
Install a Central satellite, to configure the antenna for Sirius. For this wire from the Converter plug to the input 1 of the DiSEqC switch. From its output, connect the cable to the input of the receiver (tuner), set the equipment on a satellite Sirius. To do this, connect the tuner (receiver) to the TV, perform the setup according to the instructions. In the main menu of the receiver to select "antenna Setup", set the frequency to "Manual search" 11,766 GHz, horizontal polarization "H" and the value of the flow velocity 27500 SR.
4
Adjust the signal from the satellite. To do this, select the corresponding menu, focus on the scale of "Quality". Place the antenna vertically, turn it very slowly in different directions to achieve the appearance of the signal. Once you have a signal, achieve its maximum value.
5
Next, turn on the mode "Scanning" to determine which satellite you have set up your antenna. If everything is correct, the screen will display a list of channels, respectively, of the satellite. Then strongly tighten all the nuts of the antenna, tighten them, but monitor the signal, as it can go.
