Russia, being skilled in space situational awareness SSAshould be part of the global effort to protect the space environment, experts said March 15 at the Satellite conference here. Currently, the United States provides a large amount of position information on objects in space through the Joint Space Operations Center, or JSpOC, an Air Force operation that nations and satellite operators have come to rely on for navigating through space. SSA experts say the more eyes watching objects in space, the more accurately governments and commercial operators can predict orbits for their spacecraft, and in turn, the better they can predict the likelihood of a collision.

However, they have a very different approach to sharing that information with others: We have not seen a lot of reciprocity. Conjunction notifications are alerts sent when spacecraft or debris may pass within a few kilometers of each other, raising the risk of an impact. That includes setting aside other differences for the sake of preserving the space environment. The environment stays pristine. Analyst firm Northern Sky Research tracks at least 10 companies planning to build broadband constellations of or more satellites in non-geostationary orbits. This year, SpaceX and Telesat launched prototype satellites as precursors for constellations of 4, and satellites each. Mark Dickinson, chairman of the Space Data Association SDAan international group of satellite operators that share information about satellite positions and maneuvers, also urged further transparency between nations. The low-Earth orbit satellite system would circle the equator, providing the recently tested telecom services as well as machine-to-machine and Internet of Things connectivity. Moalem said voice services, though successfully tested, cannot be commercially offered yet with just three satellites because they lack continuous coverage. Moalem said he anticipates the first launch in the last quarter ofwith the majority of the constellation deployed in Completion of the full constellation is expected by Sky and Space Global is not alone in designing cubesats for telecommunications services. Toronto-based Kepler Communications is preparing a constellation of up to Ku-band cubesats for the Internet of Things, and Swiss startup Else is building 64 L-band cubesats for roughly the same purpose. Moalem said Sky and Space Global intends to build a network operations center in London, and is investing in network management software for the fleet. Those investments should make constellation operations manageable with one primary and one backup ground station, he said. Rather than build a new ground station network, Moalem said Sky and Space Global will likely join forces with a ground station services provider — a move made possible by several companies tailoring services for smallsats. Moalem said the company plans to retire satellites earlier than that — after three to four years — replacing around 25 percent of the constellation every year. Each satellite will have a propulsion system to shrink orbits down to between and kilometers, he said, before letting gravity take over. LeoSat is developing a constellation of low-Earth-orbit satellites that will provide high-throughput communications comparable to terrestrial fiber systems.

The incident, which took place May 3 at the Michoud Assembly Facility, damaged one dome section of a tank being built for qualification tests.

  • There had been speculation that a potential reorganization of space leadership at the Pentagon might do away with the PDSA position. Wilson was confirmed by the Senate as the new Air Force secretary on Mondaybut has not yet been sworn into office. An Inmarsat satellite has been fueled for a launch next week on a Falcon 9. The Inmarsat 5 F4 satellite is scheduled to launch Monday evening from the Kennedy Space Center, joining three other Inmarsat 5 satellites that provide broadband mobile communications. The new satellite will likely be placed into service over Europe, but Inmarsat has not finalized those plans. The launch is part of a surge in activity by SpaceX that involves launches roughly every two weeks. A recent Air University study concluded private sector activities could make frequent affordable launch a reality in the near future. The contract, awarded to its KBRwyle government services unit, covers more than 20 missions operated by Goddard. China plans a series of long-duration stays in a simulated lunar habitat to prepare for eventual human missions to the moon. One group of four volunteers will spend 60 days in the habitat, followed by a second group of four who will spend days there. In the letter, Reps. The office was established in the s under the office of the Secretary of Transportation, but was moved within the FAA in the mids. Fitness levels of astronauts drop dramatically during an extended stay in weightlessness. A new study found that the exercise capacity of astronauts drops 30 to 50 percent after a six-month stay on the space station, likely because capillaries are not as effective in delivering oxygen to muscles while in microgravity.

    The finding could support both improved healthcare for astronauts on missions to Mars as well as people suffering from heart failure on Earth. GSS supplies 30 percent of the satellite capacity available in Russia through a fleet of four satellites: Yamal, YamalК, Yamal and Yamal The latter three launched between andforming the core basis for a young fleet. Yamala replacement for the Yamal satellite that launched inis under construction by Thales Alenia Space, with a launch slated for Proton. Yamal is currently under a feasibility study.

    But GSS has been able to drive up its fill rate to 65 percent by holding its ruble capacity prices, enabling customers to buy more bandwidth for the same amount. How much is international. One-third of the capacity is concentrated in the beams serving areas outside Russia. This capacity is the base for our international business. Each satellite has its own target markets for international sales. Yamal is designed for the Russian market, although it has foreign clients. Inthe company received 36 percent of the total revenue from the sales of satellite capacity in the international market. Yamal is being equipped with a C-band payload that is almost the same as the payload of Yamal, both in terms of capacity, volume and the coverage zone.

    It means that the capacity for the international market business that the company has today in C-band will not change. Yamal will be also equipped with a Ka-band payload. This capacity will be used only on the territory of Russia to deliver satellite broadband services to the various user segments, including private persons business to consumer. In the past year, financing of the project was organized. Loans for the project are provided by the Russian Sberbank. Thales Alenia Space has started the satellite manufacturing, and in two years we expect to see Yamal in orbit. This launch will give a new impetus to the development of the company. How is the broadcast business in Russia. How many channels is Gazprom supporting today. Do you see growth in HD and even ultra-HD. Notwithstanding the challenging economic situation, the broadcast business develops in a sustained way in Russia.

    Among pay-TV market segments, satellite TV constitutes approximately 40 percent, and shows the best dynamics over the last years. Currently there are approximately TV channels, including five HD channels, being distributed via Yamal satellites. That confirmed the technical capability of TV signal broadcasting in new formats via the Yamal satellite network. Almost all of these stations operate in the territory of Russia. Gazprom Space Systems said in that a new hub was needed to support Ka-band for Yamal Are those ground segment updates complete. What is your expectation for the uptake of Ka-band services. In order to deliver services in Ka-band, there will be a need to create two new hubs in the European part of Russia and in Siberiaproviding broadband services and control of several hundred thousand satellite terminals.

    Their construction is stipulated within the project of Yamal satellite creation. Now GSS selects the optimal technology and, accordingly, the equipment supplier. The works on hubs creation shall be performed in and Concerning Ka-band, we certainly see the good prospects of its use in Russia. In this band, Russian service providers plan mainly to develop broadband services for private users as well as for satellite mobile applications: We believe that point-to-point trunking will be also in demand. Yamal will cover approximately three quarters of the Russian territory in Ka-band, and the remaining fourth will be covered by the next satellite Yamal The installation of Ka-band on Yamal will broaden the customer base and geography of services, and will create a full-scale system of satellite broadband for Russia. The fixed satellite communications segment is stable, but it is currently going through a transitional period. Due to oversupply of satellite capacity alongside a complicated and thus restraining the demand growth macroeconomic environment, the competition between traditional satellite communications operators has increased. The outbreak of high-throughput systems, which marks a sort of technological breakthrough, led to a significant reduction in data transfer costs counting on one bit of information, and also had a significant impact on the industry and prices. There was a sufficiently long period in Russia towhen there was a deficit of satellite capacity. This created a significant increase in supply in the Russian market. The peculiarities of the economic situation in the country has led to some reduction in the growth rate of satellite capacity demand, which has always been higher than the world-wide average. But we feel the situation is beginning to change for the better, and we believe that in the next three years the Russian market will come to an equilibrium state. The main demand growth drivers for satellite capacity in the Russian market in the coming years will be: The ruble rose in value at the beginning ofbut is still weaker than it was in How has this affected you.

    What do you expect of the ruble in the future as it pertains to your business. The situation on the financial markets certainly affects our business, if only because we implement all our projects without government budgetary financing, using our own and attracting loan funds.

    Currently, GSS has loan commitments including in U. Due to the Russian national currency weakening in andthe sum of the obligations under these credits, calculated in rubles, increased. In order to harmonize our revenue and commitments, we also try with priority rates to increase currency earnings received in the international market. We have already returned a significant part of the loans, without any breaking commitments ever in our history, but we still have considerable repayments. In our business, we try to use generally accepted during the project financing ways to optimize the debt load, such as, for example, refinancing. Following this practice, in GSS realized the refinancing of loans acquired from tosigning an agreement with UniCredit Bank Austria AG for a new credit line in the amount of up to million euros. On November 10,Alexander Perepilichny was feeling a little under the weather. Police and medics were called to the scene, but within 30 minutes, Perepilichny was pronounced dead.
