Sleepy interference, sleepy illumination. Respect! The autumn sleepy interference begins.

Sleepy interference

Sleepy interference- Compromise of the radio signal received from the satellite, as a result of interference with the transmission of the Sun.The sun, like a mirror, vibrates energy in the visible (light) part of the spectrum, and in the visible radio spectrum, in the centimeter range. If three objects - the primary satellite antenna, the satellite on which the sun is pointed - are on the same line, receiving signals from the satellite becomes impossible. This is due to the fact that the transponder signals are blocked by the faint noise of the Sun. This is the phenomenon that people watch out for on the river - in early spring and autumn.

Sonic interference occurs between 3.5 days of autumn and spring equivalence (21st February and 21st spring). During this period, the Sun, with its river route, flows over the surface of the equator. The sunny interference in the winter, birch and winter flows into the earth's primary stations, located in the daytime latitudes, then floods the stations, installed in the daytime. On the equator, the middle of the period in which narcotic interference manifests itself falls exactly on the day of the equinox - 21 Birth. Then the interference zone is shifted at the original signal, and the remaining interference bursts are heard by stations at the same latitudes. For them, the period of sleep interference will end 3.5 days after the spring day. At the sickle, spring and evening, the picture changes to a turning point, and the fragments of the Sun at this hour collapse along the turning straight - from the Pivnichna Pivkulya to the Pivdennya. The interference period for a specific skin station lasts a little longer. During this period, the skin shows signs of interference, at the beginning of the day - for similar companions, at the end - for the closing ones.

At first, the interference appears as noticeable noise in the image and sound, then over time the noise becomes more significant, and in the middle of the interference period the reception is no longer visible.

Autumn Equine:

The remaining days of the winter - the first days of Bereznaya - the hour of spring sonar interference, the beginning of the winter - the middle of the summer - the hour of autumn sony interference for satellite primary stations of the Leningrad region. At this hour, the Sun, passing its empty path through the skyline, for many hours finds itself on the line of its companion - the primary antenna, “sinking” into the diagram of the remaining straightness. Finally, it is necessary to exert a strong force of electromagnetic vibrations in all frequency ranges, so that when interference occurs, the signal from the satellite becomes impossible to receive. This phenomenon lasts for 5-12 days, from 5 to 15 days a day at the same hour. The severity of the interference depends on the diameter of the primary antenna and the frequency range.

Why sleep interference is dangerous

• For the main systems of television companies and radio stations that directly relay the satellite signal to the airwaves: when the sun passes through the antenna directivity diagram, the inevitable result is a gateway to the airwaves.

Respect! Autumn sleepy interference begins

On the 27th of spring, the period of dream interference began in Russia. At this time, the Sun, the satellite connection and the primary antenna of the ground-based satellite station are connected on the same line, which leads to a decrease in the brightness of the reception of television and radio channels from the satellite until it is completely lost. Interference occurs two days on the river, stretching three and a half days on the days of autumn and spring (21st Spring and 21st February).

RTRS uses all technical capabilities to minimize the influx of sleep interference on the reception of television and radio channels by TV viewers. For satellites that have different orbital positions, the hour of unpleasant influx of solar interference varies. Therefore, RTRS branches organize local reception of TV and radio channels from backup signal channels.

Both backup devices can be used as digital program packages (federal version of the first multiplex and another multiplex), as well as direct communication satellites (program packages “Tricolor TV”, “Tricolor TV Sibir”, “NTV-Plus”, “NTV-Plus” Skhid", "Continent TB" etc.).

The majority of TV viewers in Russia do not notice interference.

Sleepy interference- The signal is received as a result of vibrations when the ground station-satellite station is close to the axis.

On a global scale, solar interference manifests itself two days a week during the period of 3.5 days of spring and autumn (20-21 February and 21-22 spring respectively).

The spring interference starts from the ground station in the daytime, goes to the equatorial ones (as long as the interference falls exactly on the same day), and then goes to the station during the day and pіvkuli. In the spring, everything repeats itself at the gateway.

From the point of view of the ground station, the interference lasts for 5-12 days, during which, when passing across the sky, the sun moves the entire satellite antenna for 1-10 days, at the leading hour for the station of the convergent song, for One - in the evening. At the beginning of the interference period, it appears as a decrease in the level of the signal and an increase in the number of signals, until the middle of the period it appears to be received at all.

For a particular ground station, the hour at the beginning and the end of the interaction can be resolved to the nearest second. Output data for the breakdown:

• Roztashuvannaya companion
• ground station coordinates
• antenna diameter
• range (Z abo K u)

On a duplex communication channel (between two ground stations), interference is indicated by two - initially the reception of one ground station, then the reception of another.

Skoda, which suffers from sleepy interference

In front of us, the interference destroys the bitterness of the connection and induces its effects, which are indicated on the basis of the services that are received from it. The only way to escape is to later switch to another satellite (with a different interference period) or an alternative communication channel.

Some positioning systems for satellites in poor orbits may begin to follow the sun in place of the satellite in the face of interference. Positioners susceptible to such an effect are recommended to be disabled or switched to geostationary mode during the hour of interference.

Antennas of large diameter, coated in light colors in sunny weather, focus light on the converter (or damage), which can lead to fire, melting of plastic parts and damage to your electronic components. To avoid damage, for such antennas it is recommended to shield the converter with a sheet of radio-transparent material (cardboard, plastic, etc.) for an hour of interference.

But in satellite technologies the sun is a dead end. How are you going to ask?

Everything is just thermal energy, which resembles the sun, even stronger than before. If the sun is in the same line as the transmitting satellite and the antenna that is being received, it will jam the blue signal from the satellite.

For greater understanding, you can level the rosemary on the hub, if the noise from the car passing by drowns out your rosemation and slightly the sedative.

If there is a receiving antenna, it is impossible to separate the required signal through a wireless transmitter from the sun. If the signal doesn’t reach you, you won’t be able to reach a moment of sunlight.

This happens rarely, but mostly in spring and spring. All to the fact that at this very hour all these factors are avoided. Such periods are called SONIC INTERFERENCE or else sleepy lights. It also means there is no signal on your satellite device.

The triviality of the influx of sleepy signals depends on the geographic location of the primary antenna, its diameter, the orbital position of the satellite, and the type of transmitting frequency. It all starts with short hours, a trivial amount of pain, wasting a signal. What to notice about the approaching sun before the light comes on, so that you stay in one line.

The heat from the sun on the table is tighter, which makes it possible to clearly recognize the cortical signal from the satellite even when approaching the point of sunshine illumination. The closer you are to the direct line with the transmitting and receiving antennas, the more important the periods of solar interference become. However, after passing through the most unsafe zone, the sun begins to move away and we no longer become unsafe for the received radio signal.

Depending on the position of the satellite and adjusted on a new satellite antenna in one geographical point, the influx of solar interference changes throughout the day at the appropriate hour. More similar satellites will initially appear under the influx, and then the illumination will move from one to another antenna in the incoming direction to the satellites in orbit. All because the earth rotates on its axis at the same time as its geostationary satellites, thus the sun eventually changes its position to become our primary antenna.

The severity of the periods of sleep interference is proportional to the size of the satellite antenna and the indicator of the non-frequency. In other words, the larger the diameter of the satellite antenna, the shorter the interference period and the lower the transmission rate. Well, the smaller the antenna you have, the longer periods of overexposure.

The sun, like a mirror, vibrates energy in the visible (light) part of the spectrum, and in the visible radio spectrum, in the centimeter range. If three objects - the primary satellite antenna, the satellite on which the sun is pointed - are on the same line, receiving signals from the satellite becomes impossible. This is due to the fact that the transponder signals are blocked by the faint noise of the Sun. This is the phenomenon that people watch out for on the river - in early spring and autumn.

Sonic interference occurs between 3.5 days of autumn and spring equivalence (21st February and 21st spring). During this period, the Sun, with its river route, flows over the surface of the equator. The sunny interference in the winter, birch and winter flows into the earth's primary stations, located in the daytime latitudes, then floods the stations, installed in the daytime. On the equator, the middle of the period in which narcotic interference manifests itself falls exactly on the day of the equinox - 21st Vernal. Then the interference zone is shifted at the original signal, and the remaining interference bursts are heard by stations at the same latitudes. For them, the period of sleep interference will end 3.5 days after the spring day. At the sickle, spring and evening, the picture changes to a turning point, and the fragments of the Sun at this hour collapse along the turning straight - from the Pivnichna Pivkulya to the Pivdennya. The interference period for a specific skin station lasts a little longer. During this period, the skin shows signs of interference, at the beginning of the day - for similar companions, at the end - for the closing ones. At first, the interference appears as noticeable noise in the image and sound, then over time the noise becomes more significant, and in the middle of the interference period the reception is no longer visible. At the time of interference, especially in clear weather, it is necessary to remove the antenna from the satellite if possible. Rolled aluminum reflectors and plastic reflectors with a glossy surface concentrate solar energy at the focal point of the table “successfully”, so that the plastic parts of the frames are melted through high temperature and get the electronics of the converters in order.

Days, hours, and the end of sleep interference for the skin companion for a specific primary station can be covered absolutely accurately.

Output data for the breakdown:

1. The geometry of the mutual rotation of the Earth, the primary station, the satellite and the Sun;
2. Strengthening the antenna and the width of the head pellet with straightness diagrams;
3. Vickory frequency range;
4. Noise temperature of the primary system;

Autumn Equine:

The last days of the winter - the first days of Berezny - the hour of spring solar interference for satellite primary stations of the Urals and Western Siberia. At this hour, the Sun, passing its empty path through the skyline, for the next hour finds itself on the line of its companion - the primary antenna, “falling” into the diagram of the remaining directness. Finally, it is necessary to exert a strong force of electromagnetic vibrations in all frequency ranges, so that when interference occurs, the signal from the satellite becomes impossible to receive. This phenomenon lasts for 5-12 days, from 1 to 8 days a day at the same hour. The severity of the interference depends on the diameter of the primary antenna and the frequency range.

Why sleep interference is dangerous

1. For the main systems of TV companies and radio stations that directly relay the satellite signal to the airwaves: when the sun passes through the antenna directivity diagram, the inevitable result is a gateway on the airwaves. To avoid this, it is necessary to prepare an alternative signal and switch to it later.

2. For stations that receive signals from satellites “Obriy”, “Express” with poor orbits from satellite receivers-positioners Drake ESR-700, Drake ESR2000XT-plus, Pansat XR4600D: under an hour of interference The receiver can “throw” the satellite. To prevent this from happening, you must first program the required satellite in the receiver as a geostationary satellite in order to turn on the power for the hour of interference. After renewing the satellite, you can become a satellite again from a low orbit. If the main part of the receiver is not victorious, then during the hour of interference it can simply be switched to Standby mode.

3. For stations that receive signals from satellites “Horizon”, “Express” with poor orbits from the satellites of the intelligent surveillance controller RC2000B, RC2000C from Research Concepts Inc.: if the hour of interference is carried out, the transfer procedure is carried out If you enter the row table data, the controller will close the table row. This can lead to repeated use through supplementation until the interference ends. To prevent this from happening, you need to turn on the controller in advance for an hour of interference, and turn it off again after receiving the signal again.

4. For most systems that use large-diameter antennas, light-colored ones are used: in clear weather, during the interference period, the antenna is focused on the converter. This can lead to melting of the plastic parts of the converter and the electronics output. To prevent this from happening, it is necessary to place a screen made of cardboard or non-transparent polyethylene before opening it.

How to determine the hour of dream interference

1. You can quickly use the simple calculator program look.exe, which can be easily accessed on the Internet from ftp://mckibben.com/look.exe. This is an MS DOS program that requires installation. The program is simple, it only gives the date when the severity of the interference is maximum and the hour in the middle of the “session” of the interference. To determine the first and last days of interference, it is necessary to select the date back and forth for a number of days, which is indicated by the same program with the antenna diameter and range. It is also necessary to work through the clock in order to remove the earliest hour of the beginning and the latest hour of the end of the interference. The program only works for primary stations of the Pivnichnoy Povkulya. The look.exe program can be found on our website (66 kB).

2. A very handy in-line calculator, which is available on the PanAmSat website. To determine the time of interference, you need to enter the orbital position of the satellite (or select a satellite from the list), geographic coordinates of the primary station (or select a place from the list - there are Russian places !), Select frequency range (C-Ku), season (spring - autumn ), enter the antenna diameter in meters, then press the Calculate button. The program will show the breakdown of the beginning hour, the end hour and the trivialities of interference today. It can be extracted from the html-file, to be unzipped or saved on disk, for which you just need to press the Print/Save As button

The program works for any point on Earth, it is oriented at the main station of the USA, so when entering the data you must verify actions of particularity:

• The orbital positions of the satellites are measured in degrees of sunset latitude around the world from 0 to 360 W (from the Greenwich meridian to Sunset). For satellites that are located above the Convergence area, it is necessary to enter the similarity values ​​with a minus sign, or overestimate the similarity in the roundabout world and the outflow in the circle: W = 360 - E
• The longitude of the receiving point may also be entered in degrees of entering latitude around the world. For similar yield, it is necessary to put a “minus” in front of the similar yield values ​​or convert them into the entry for the same formula.
• When entering the antenna diameter for half a dozen digits, select the point, not the one. When you enter a number, the program will appear.
• Remember that Americans write the date: month-day, not month-day.
