    Russia to develop Glonass orbital navigation system with six new satellites

    This will improve the accuracy, accessibility and integrity of the system, Roscosmos believes

    MOSCOW, November 21. /TASS/. Russia will continue developing its Glonass orbital navigation system with the launch of six new satellites, First Deputy CEO of State Space Corporation Roscosmos forRo Orbital Grouping Development and Priority Projects Yuri Urlichich said on Wednesday.

    "We will have new satellites in other orbits that will help us solve the tasks of improving accessibility on the territory of Russia. We are planning to launch six space vehicles that will qualitatively improve the Glonass system. This will improve the accuracy, accessibility and integrity of the system," Urlichich said at the 8th Era-Glonass international congress.

    ‘What will this yield for us as consumers? Intellectual transport systems will become even greater reality and humans’ work in them will become even less and unpiloted systems will emerge. Of course, there will be those willing to drive automobiles themselves but gradually they will find themselves on special tracks and special roads," the Roscosmos official said.

    "As of today, producers predict a total reduction in the production of automobiles. However, the human population is growing and there will be more rides but they will be unpiloted as unpiloted transport, both freight vehicles and cars, is awaiting us," he noted.

    In 2011, Russia launched its first Glonass-K satellite, which has been undergoing flight trials since then, and in 2014 its analogue was launched, Urlichich said.

    "In 2019, we are already waiting for the Glonass-K2, which will enable us to solve many tasks with a better quality. As of today, the Glonass orbital satellite grouping comprises 24 vehicles in their standard operation and it will continue developing," the Roscosmos first deputy head said.

    Today, only two navigation systems have been fully deployed in the world: the Russian Glonass and the US GPS. The Chinese Beidou system and the European Galileo will be deployed but they are lagging behind, he said.

    "The European system is more than 15 years late compared to its initial plans while we have been able both to create and maintain our system and we are creating products on its basis, such as the Era-Glonass - the emergency response to traffic accidents. When we were starting the Era-Glonass program, we were behind Europeans. But we have managed to make it first and this is the first national system of such a scope," the Roscosmos official said.

    New generation satellites to join GLONASS system early 2020

    NOVOSIBIRSK, April 9. /TASS/. New generation satellites will join the navigation system GLONASS at the end of 2019 or the beginning of 2020, the deputy CEO, deputy general designer for development and innovations of the JSC M.F. Reshetnev Information Satellite Systems Yuri Vilkov has said.
    "We are in the phase of developing a new generation of navigation satellites. They will replace the current ones and considerably improve the system’s parameters, including accuracy. The satellites boast better energy and mass characteristics. The first ones in the new series are to be launched at the end of this year or the beginning of next year," Vilkov said.

    He explained that a specific date could not be disclosed right away, because it depended on the life cycle of the existing technologies. The GLONASS system, he added, is rather stable and most of the satellites already launched stay operational much longer than their declared life cycle, so there is no need for their prompt replacement.

    GLONASS is Russia’s a global navigation satellite system. Guaranteed global coverage requires 24 operational satellites located in middle circular orbit at 19,100 kilometers - eight satellites in each of the three orbital planes. The orbital group is controlled from the information and analysis center of the Central Research Institute of Machine Building TsNIIMash.

    New satellites to improve accuracy of Russia’s Glonass orbital grouping to onemeter


    Such accuracy will better determine the location of cars, to be helpful in analyzing a traffic accident and restoring the circumstances, Glonass Company Chief Designer Mikhail Korablyov said

    ST. PETERSBURG, May 31. /TASS/. New Glonass-K2 satellites will improve the accuracy of Russia’s satellite navigation system from 3-5 meters to 1 meter, Chief Designer of Glonass Company (the operator of the Era-Glonass traffic accident emergency response system) Mikhail Korablyov told TASS on the sidelines of the Transport Security forum on Friday.

    Russia is currently drafting a new federal target program for developing the Glonass orbital navigation system in 2021-2030. The program is due to be drafted by 2020.

    "The tasks [stipulated in the federal target program] envisage further developing and fully deploying the grouping on the basis of Glonass-K2 satellites and increasing accuracy. The navigation accuracy is about 3-5 meters today and we are set to improve it to less than a meter by the end [of the program’s operation]," he noted.

    Such accuracy will better determine the location of cars, which will be helpful in analyzing a traffic accident and restoring the picture of the accident’s circumstances, the chief designer said.

    "There are also tasks linked with the country’s defense, there are special precision weapons, the requirements for which already make up less than a meter," he added.

    As was reported earlier, Russia’s strategy of developing the Glonass satellite orbital grouping through 2033 stipulates that from 2030 the Glonass system will fully consist of 24 new Glonass-K2 space vehicles that will be manufactured using only domestic components.

    The Glonass-K2 is due to become a follow-up of Glonass-K satellites (two such satellites are operational in the Glonass orbital grouping). The new satellite will be transmitting nine navigation signals and will weigh about 1,800 kg (twice as much the Glonass-K). Russia plans to launch the first Glonass-K2 satellite into orbit in late 2019 - early 2020.

    Russia’s Glonass navigation satellites to switch to domestic components by 2023


    The program of replacing foreign components with domestic items was launched in 2018

    MOSCOW, June 14. /TASS/. Russia’s program of fully replacing foreign components in Glonass navigation satellites is due to be implemented before 2023, Chairman of the Roscosmos State Space Corporation’s Scientific and Technical Council Yuri Koptev told TASS on Friday.

    "A four-year program exists for the Reshetnev Information Satellite Systems Company as the developer of Glonass satellites. The program has been agreed upon with the developers of the components base. Each year, the program defines a specific set of Russian components to replace foreign analogues," Koptev said, adding that the program was designed for a period until 2023.

    The program of replacing foreign components with domestic items was launched in 2018. It stipulates that Glonass satellites will carry no foreign components in the future, he noted.

    Under the strategy of developing the Glonass orbital grouping through 2030, the launch of the last Glonass-M satellite is scheduled for 2020 while the last Glonass-K space vehicle is due to be delivered into orbit in 2023. Roscosmos Chief Dmitry Rogozin said during a lecture at Moscow State University that the first Glonass-K2 satellite was planned to be launched in late 2019 - early 2020.

    The Russian 5th column press and liberasts were chirping that this satellite would never be launched because import substitution
    of foreign components would result in massive corruption (like actually happens in Banderastan) and Russia would prove that
    it cannot into tech. We had articles on RBC claiming that Russia was officially discontinuing Glonass satellite production even
    though there was never any such move.

    The template for this anti-Russian, NATzO sycophant BS is always the same. And always totally wrong. Liberasts have a
    compulsion to cherry pick from and deny reality. They are the definition of sociopaths and clearly have serious mental issues.

    Rogozin spoke about the accuracy of the GLONASS system
    Evgeny Shakirov
    December 31, 2020

    The accuracy of the GLONASS system at the moment is 2.5 m. This was announced by the head of Roscosmos Dmitry Rogozin on Thursday, December 31st.

    “Next year we will launch several spacecraft into orbit (Glonass-K - Ed.) And begin updating the constellation. They will be more accurate. Now we have the permission given by our navigation group - this is more than 2.5 m accuracy, and so it will be 1.3, ”Rogozin said on the air of the Russia-24 TV channel.

    He also added that in 2025 it is planned to transfer the entire GLONASS grouping to Russian electronics.

    Last week it became known that the new-generation navigation satellite "Glonass-K", launched into space in October, will replace the previous generation apparatus that failed prematurely in orbit.

    The orbital constellation of the Russian global navigation satellite system GLONASS includes 28 spacecraft (25 Glonass-M and three Glonass-K), of which 23 operate as intended, two are in flight tests, two are undergoing maintenance and one is in reserve.

    China will add reliability to Russian space, by Mikhail Kotov for VZGLYAD. 03.21.2023.

    Russian satellite navigation will receive support from China.

    Is it possible to disconnect Russian residents from global satellite navigation systems? How to ensure the success of Russian technologies in such a sensitive area? The answer to this question is provided by documents on new forms of practical interaction between Russia and China, which appear during the visit of the Chinese leader to Moscow.

    The Russian government instructed Roscosmos, together with the Russian Foreign Ministry, to coordinate with China the creation of a subcommittee on cooperation in the field of satellite navigation. The document, signed by Prime Minister Mikhail Mishustin, has been published on the Legal Information Portal.

    According to the document, it is proposed to strengthen the practical interaction between Russia and China in the field of satellite navigation, to ensure the compatibility and complementarity of the Russian GLONASS and the Chinese Beidou system. Why is this necessary and how useful is such work for Russia?

    Oddly enough, but since the launch of spacecraft for global geopositioning (in this case, the Russian GLONASS system) on Earth, work has only just begun. It just seems that satellites work independently in space, and those who use the constellation can only relax and only receive a signal. In fact, the ground services responsible for the functioning of the group are constantly working to ensure that the coordinates are determined as accurately and quickly as possible.

    GLONASS satellites operate at an altitude of 19,400 kilometers. At the same time, the orbit of spacecraft is optimized for use at high latitudes of the planet, that is, where the territory of the Russian Federation is located. Under normal conditions (in open areas) from anywhere in Russia, the device must see at least four spacecraft to determine its exact coordinates (three signals provide accurate triangulation, the fourth is a control one and helps determine the height above sea level).

    How does this happen? Spacecraft transmit signals that are received by a chip inside your smartphone and thereby allows you to determine its (and, accordingly, your) location. The chip measures the time it takes the signal to reach the device.

    Knowing the positional point of each of the spacecraft of the navigation system, this method can determine its exact location.

    The problem is that even at such a high altitude, spacecraft are gradually but inexorably changing their position in orbit. This is due to many factors, including, for example, the solar wind.

    The change relative to the circumference of the orbit is almost imperceptible, but it can make its own adjustments to the determination of the location. Therefore, the ground services of each of the satellite navigation systems are constantly working to determine the exact coordinates of each satellite and enter these changes.

    There are two types of information about the location of spacecraft in orbit - almanac and ephemeris. The almanac contains the parameters of the orbits of all satellites, and each satellite transmits the almanac for all spacecraft in its constellation. This data is valid for several months and is intended to provide a rough indication of which spacecraft are currently overhead. And so that the search for satellites and obtaining information does not have to be started anew each time with its constant use and when moving a few meters, there are so-called hot start systems.

    In addition, each spacecraft transmits with a signal to the user its own and only its own ephemeris - data that contains the most accurate corrections of the orbit parameters for each device. It is they who provide the maximum accuracy of determining your location.

    Surely you have noticed that sometimes in the first seconds the smartphone determines the location less accurately. This is due to the fact that the chip has not yet received ephemeris from the satellite, they are sent to users every half a minute. As soon as the chip receives this information and makes corrections, the accuracy of determining the coordinates increases to a couple of meters. There is another option for obtaining ephemeris via the Internet, the so-called hot start system (A-GPS), this is the general name for such systems, regardless of the grouping.

    That is, there is a lot of work on Earth. And this work really greatly affects the usability of the navigation system.

    In the event of the start of work on cooperation in the field of satellite navigation, Russia and China will begin to exchange information on refining the orbits of spacecraft. Perhaps the parties will start creating programs to increase the accuracy of determining coordinates. In recent years, Russia has already carried out such a program on its own - and some improvements have been achieved. Together with China, such work will be even more effective. Probably, it will be possible to increase the accuracy of navigation even more.

    Yes, modern chips use data from all the spacecraft that the satellite sees - both the American GPS and the European Galileo. Nevertheless, the accurate and uninterrupted operation of its system is one of the most important conditions for national security.

    In the summer of 2022, voices were already heard with ideas to “disconnect” Russia from the GPS global navigation system.

    The ideas themselves are crazy, but the general direction of thoughts is clear. In this situation, it is critically important for Russia to independently maintain the performance of GLONASS at the maximum level.

    Partnership work on an equal footing with China is also a very good help in this story. Unification of signals, joint testing of systems. In addition, two systems in the event of some serious opposition are always better than one, more reliable.

    A separate conversation is the work to expand cooperation in the international program COSPAS-SARSAT, the international satellite search and rescue system. In case of emergencies on ships and aircraft, it announces the distress and the location of personal radio beacons installed on vehicles. GLONASS satellites are also part of this system, which has already saved more than tens of thousands of lives.

    Either way, working together is good. Especially when it is carried out on an equal footing, and in this type of cooperation, this is undoubtedly true.

    "Soyuz-2.1b" with a spacecraft in the interests of the Russian Defense Ministry launched from the Plesetsk cosmodrome

    MOSCOW, 7 August. /TASS/. Crews of the Space Forces of the Aerospace Forces of the Russian Federation launched the Soyuz-2.1b carrier rocket in the interests of the Russian Defense Ministry. This was reported to journalists in the Russian military department.

    "On Monday, August 7, at 4:20 p.m., from the State Test Cosmodrome of the Ministry of Defense of the Russian Federation (Plesetsk Cosmodrome) in the Arkhangelsk Region, combat crews of the space forces of the Aerospace Forces launched a Soyuz-2.1b medium-class launch vehicle with a spacecraft (SC ) in the interests of the Russian Defense Ministry," the ministry said.

    In 2023, this is the 10th launch of a space launch vehicle, the third from the Plesetsk Cosmodrome.
