The fourth measuring station GLONASS began work in Brazil

The Roskosmos press service reports that the fourth GLONASS measuring station has started its work in South America. We are talking about the so-called request-free measuring station (LSI), which from today will be operated in Brazil. BIS began its work on the territory of the Brazilian University of Santa Maria.

The developer of the BIS SM-GLONASS is structurally part of Roscosmos JSC NPK SPP.

From the message press service Roscosmos:

The ceremony was attended by Yury Roy, Director General of NPP SPP, Gennady Sayenko, official representative of Roscosmos State Corporation in Brazil, Sergei Akopov, Russian ambassador to Brazil, Jose Cardoso, Brazilian Minister of Justice, and Paulo Burmann, rector of UFSM (United Federal University of Santa Maria).

For reference: LSI SM-GLONASS is a station designed for continuous tracking of satellite signals not only from the GLONASS orbital constellation, but also GPS, Compass and Galileo. The station allows you to read the current navigation parameters, receive satellite navigation messages, record the measurement results and transmit data to the SVO EVI center (a global system for highly accurate determination of ephemeris-temporal information).

Ephemeris-time support is provided by a special set of software and hardware that monitor the orbits of satellites. In addition, trajectory measurements are carried out and the calculation of ephemeris information directly.

Too shy to ask - does the station have a dual purpose?

GLONASS has a dual purpose, and this station is intended only to improve the accuracy of the navigation system.

Suddenly, purely by chance, it may turn out that there is also someone else to reduce the accuracy of someone else. ;)

Well, where is the alarmist who wrote that everything was lost? That the state steals all the money? See, not all. How easy it is to scratch with your tongue, "Yes, I would have shot all" embezzlers ... In short, drop dead news, cool !!!!

I’ll clarify, over both Americas (we have dual-use all of space), and our fleets do not only go through the marquise puddle, they must be provided with accurate navigation, otherwise gps may happen by the will of the owner

What are you, what are you! Of course only satellites!

The Navy, VKS and missiles will find our targets for sure. Also, each of us, having a navigator in the car or in our pocket, will not get lost in an unfamiliar area.

Information transmitted by these stations is open to anyone. A rocket will fly where necessary without them, but complex geophysical equipment will not work without them.
Previously, a network of Triangulation towers was deployed throughout the country. All surveying was tied to them. Now the location with an accuracy of several millimeters is determined by GPS signals.

Glonass, like jeepies, originally had a military purpose, and civilian use is a consequence.

Navigation systems around the world are designed and built by order of the Ministries of Defense, and their main task is to fulfill the relevant tasks of the military departments, including the precise guidance of missiles. And only secondarily are civil positioning systems.

For "full-fledged" GLONASS operation, 50 pcs are required. measuring stations to be located in 36 countries. we asked the United States to place 2012 of our stations with them, but the CIA and the Pentagon did not recommend the State Department to give consent (increasing the "accuracy" of GLONAS). At the same time, there are 8 American GPS stations (installed in the 19s) on the territory of the Russian Federation. We hinted that we will respond to the ban in a mirror image. At what stage is this question now, I have not met the information.

Have we already dropped Cuba from our accounts?

These stations increase accuracy in the area where they are installed. That is, in the Western Hemisphere. And without them, you can quite accurately reach the goal. But with these stations, accuracy improves. I’m not sure that Brazil is the most ... But the Americans do not allow them to be placed at home. The mirror answer begs for a long time.

Ha, but in Russia everything has a double meaning. Well, except for men and our women of course. And so - life made too many friends around.

Well, about the men, I agree. Lie on the couch, drink beer and watch TV. But the woman is worse, And feed the children to wear, Earn money for clothes and housing, and feed the drunk on the couch. This is more than a dual purpose.

Let them be healthy! At the hour "h" the signal will be muted or distorted. :-)

[Bakht]

Which signal? At what frequency? The second frequency (standby) is unknown a priori. And there are no complex signals. Just an impulse. The system operates on a simple time measurement. That is, for the operation of GLONASS or GPS you need a good chronometer. :-)

As soon as we learned how to make good chronometers and launch them into space, GPS appeared. But the chronometer is really good (atomic cesium clock). Time is measured up to the 9th decimal place. This is if in seconds. So simple arithmetic shows that the accuracy of the system cannot be less than 30 cm. But this is in theory. In practice, much worse (up to a few meters if you're lucky). Here, to increase accuracy, these stations on Earth are also required.

PS Our navigators have always prided themselves on the accuracy of coordinates. To which I modestly pointed out the diameter of the mast. And the diameter of the plate is generally about 1 meter. What millimeters they talked about is still incomprehensible to me. And for the exact operation of the system, they always needed 5-6 satellites. On 4 satellites, the accuracy dropped dramatically. Although in theory you need 3 satellites. Favorite joke: "Can you get by with two"?
