Ten Iridium communications satellites were released on Friday at the Falcon 9 rocket orbit in California on the eighth and final launch of the Iridium network in the last two years and planned the 18th SpaceX missions in 2019.

The 999-meter-tall (70-meter) Falcon 9 rocket raiser its nine major Merlin 1D engines and the Launch Complex 4-East Vandenberg Air Force Base (California) remotely went 7:31:33 a.m. PST (10: 31:33 a.m. EST; 1531: 33 GMT) Friday.

Falcon 9 flared off into a dark sky over the Pacific Coast of California, south of the Pacific Ocean, and its first booster stage was launched to land around Vummer's 150-mile (250 km) spacecraft around SpaceX's drone.

Landing seasoned in 33rd season SpaceX retrieves one of its rockets after launching the orbit, and the second specific Booster mission was launched on Friday, during the Cape Canaveral flight in September.

The second stage of Falcon 9 stopped in the orbit, trying to manipulate its Merlin engine twice, to get rid of an iridium of 1,896 pounds (860 kilograms) to handle 388 miles (625 km) altitude. The next satellites are simultaneously two dispensers mounted in the Republican rocket.

Iridium's lower controllers have rapidly received signals from new satellites, when their health reaches an orbit and launches eight SpaceX, the Iridium Network Recapulation XXI. Modern century nuclear space.

Matt Desch, the chief executive of Iridium, told Spaceflight Now on the telephone conversation, the launch of the Iridium 75 new-generation satellite high-speed data transfers, better voice communications and second-class missions and sea surveillance.

"I am still processing, because this epic and massive commitment is something that is a gratifier," Desche said. "Obviously, I'm in vain, but I'm a bit annoyed that we are not doing now. It's so fun to start it up and work it smoothly. But I'm going to go ahead and try to think all the things we'll do with these satellites.

"I am proud of my group and everyone Iridium is proud of and they have continued with us," said Desche on a telephone interview on Friday's Vandenberg. "And I'm very happy about all the fans we've been doing along the way, who cheer on us."

Iridium ordered the Iridium 81 Thales Alenia Space and Northrop Grumman Innovation Systems to build a nuclear-based assembly line in Gilbert, Arizona. In June 2010, after less than two weeks of the Falcon 9 rocket missile, Iridium announced an almost 500 million dollar SpaceX contract to orbit its satellites.

At that time, Iridium and SpaceX launched the first series of satellites in 2015 and planned to complete the 2017 network. In 2015 and 2015, the delays in the Falcon 9 rocket defects occurred in 2015.

But eventually, SpaceX placed Iridium's next 75 satellites in orbits. The remaining six spaceships will be on the ground, but they can be launched in the coming years to complete Iridium constellation backups.

"Commitment, we saw passion, we saw a technical experience with experienced people," said Ichirik SpaceX decided to fly its satellites to Iridium. "We saw Elon (Musk) and (SpaceX Chairman) Gwynne (Shotwell) and the key managers of our work (SpaceX CEO).

"I would not say reuse and landing focused on all rockets and things," said Desch. "We were more than just the ability to start up efficiently. I know they also developed enough time. We still did a lot of 75 satellite construction work.

"I really appreciate the fact that Gwynne was here today. We wanted to get to know what we first knew in 2006 and gradually grew together. Many people thought what we were trying for at that time was crazy and brave, and it was difficult for our story. He thought the same thing. Here are a few years later, and we both got what we got. So we always get together together as we have grown and succeeded in our successes, "Desche said.

SpaceX has made plans for 18 Falcon rocket missions 2019

Hans Koenigsmann, vice president of SpaceX, construction and flight reliability, said last month that the company is organizing around 2019 Falcon rockets.

"We have run for 18 years for the next year, but less than or less than one year, that can easily happen," said Koenigsmann on December 5 at a press conference at the Kennedy Space Center in Kassedy.

SpaceX launches this year's two flight tests for the two-crew Crew Dragon spacecraft, an astronaut, as early as February, after the International Space Station, with a NASA astronaut two-week ship, in the middle of the year. These missions take place on schedule and, successfully, the third Crew Crew capsule can be launched at the end of 2019 at the station's first operational flight crew, and NASA completes its relationship with Russia to transport Earth's astronauts into the Earth's orbit.

It is also planned in 2019: Two Falcon Heavy launches a satellite satellite communication platform from Arabia and the US Air Force's load-load set. SpaceX aims to launch a series of satellites around the company's planned Starlink broadband network, as well as three unpiloted Dragon cargo space missions and another starting point for the US Air Force GPS navigation satellite. To do this, he continued the first GPS Falcon 9 tracking. 2018 closure

Similarly, the release of Falcon 9 this year in Cape Canaveral will establish satellites for satellite geostation communication, PSN 6, video, voice and data relay crafting from NT Pasifik Satelit Nusantara to Indonesian operator. Satellite PSN 6 satellite, manufactured by SSL, will last until mid-September, mid-February, developed in the southern Israeli private land Beresheet, the word "genesis" in Hebrew.

Other commercial communication geostation charges are scheduled to launch Falcon 9 rockets this year, including Israeli-based Spacecom Ltd. satellite satellite programming Amos 17 satellite programming from June to June, and JCSAT 18 / Kacific 1 high-throughput satellite satellite broadband Asia-Pacific coverage for the third quarter of each year – between July and September.

Sirius XM Radio SXM 7 satellites will also be released at the end of 2019 or early 2020 at Falcon 9 rocket.

In addition to flights from the two flight launches for SpaceX Florida, four of the Falcon 9 launched by Vandenberg Air Force Base this year, following the role of Iridium on Friday.

SpaceJ's next launch in Vandenberg will lead the Canadian Radarsat Constellation Mission, a three-satellite radar image set, to enter into the orbit of the Falcon 9 rocket. The California 9 Falcon 9 release of Californian aims to expand the satellite fleet of the German military satellite, and the SAOCOM 1B radar satellite satellite Falcon 9 satellite satellite is scheduled at the end of 2019.

SpaceX also plans to test the abortion of the atmospheric flight space of the Crew Dragon space over the next months before the astronauts fly to the orbit of the ship. NASA's Kennedy Space Center flight testing will use a standard Falcon 9 rocket that will only be missing a 39A pad from the second stage, and the Crew Dragon capsule will activate the spin-off spot for roughly one minute and parapet in the Atlantic Ocean When the abortion vehicle is dismantled after the abort command has been made.

Twenty-one Falcon rockets started in 2018, all successfully. 18 The growth of the Falcon rock missions has been in 2017.

SpaceX has launched 40 successful direct missions in September 2016 after losing a Falcon 9 rocket.

This year's launch schedule will see changes to the missions that will be launched in SpaceX, and it will also be possible to see the extent of the commercial launch industry.

The geostationary orbiting missions that perform large remote sensing missions are more commonly used in commerical marketing than in more than 22,000 miles (35,000 km) in Ecuador. SpaceX sent seven shipments to the geostationary transfer orbit in 2017 and continued eight flights in 2018. This year, four or five geoestables were launched in SpaceX's manifesto.

The mission missions for smaller satellites are now more common, with national Earth observation programs and "mega-constellation" commercially launched.

Iridium is ready to open new services

Nowadays, with modernized satellite fleets, Iridium has launched a new era with expanded capability, new services and money-wasting revenue.

The Iridium communications network operates on 66 active satellites in six orbital planes, plus spare parts, connects satellite radio to the voice and data traffic without connecting to the Earth's lower stations.

The company's first generation "Block 1" satellites, built by Lockheed Martin, were launched from 1997 to 2002 and were designed for seven-year missions. Most of the fleets have overcome their long-term projection and new satellites are substitutes for the company's obsolete aging and obsolete 1990s, and the introduction of new Iridium bread and butter vehicles through the phone. message relay functions.

The satellites entered the Iridium fleet's 3rd plane, and in the second, the launch window appeared to be loaded directly into the orbit.

Iridium Certus, the new Iridium services, will allow the transmission and delivery of broadband messages to clients, including high definition videos and Internet connections. In the design of boats, aircraft and other users, Iridium Certus will provide Iridium customers with a maximum of 1.4 megabytes of bandwidth L bandwidth, with 128 kilobits per second second satellites.

After Iridium Next satellite, he has also hosted an air receiver at Aireon, a member of Iridium, in collaboration with European and Canadian air traffic authorities. Aircraft equipment continues air circulation around the world, including plans that travel outside of conventional ground radars.

"We went on to the bottom of Iridium Next in 2007 and started in 2010. We were very excited about what happened in the last two years in the last two years, on January 14, 2017, amazing and very important, but our latest launch … the most important milestone is far away. " Desch said.

"I'm sure you can imagine some reasons," he continued. "To finish $ 3 million redevelopment, we can launch new services like Iridium Certus broadband, more efficient IoT (Internet of Things) and Aireon, to enable Iridium's financial transformation, but for me, startup is even more important, the creators of the system realized that they had been dreaming for more than 30 years, which means that our network will achieve the security of the financial independence and security satellite operator successfully, and that we never have the chance to create many opportunities, which is our customers, our partners and also in relation to the sector.

Originally sponsored by Motorola, Iridium was a pioneer in the communications and communications industry, placing its large satellite satellite commercial in its orbit. But Iridium was named bankrupt immediately after deploying the initial satellite range. An iridium-active company was created, a new business strategy, high prices and low demand, which was condemned to the original concept of Iridium, including satellites already in space.

Iridium has more than one million subscribers in its list of customers, and the United States Department of Defense is one of the company's leading customers with aviation and sea operators, land transportation providers and mining, forestry and oil and gas industries.

"What will happen next after Iridium? This answer is a lot," Desche said. "Special emergency broadband service is a brand like Iridium Certus, the name of the Certus is Latin, and we can say that they are reliable, inaccurate, uncertain, and accurate. All indicators clearly define Iridium and our broadband service.

"We completed 2018 tests and Iridium Certus marketing and almost complete data rehearsal, which is made up of some of our service providers, which offers customers the opportunity to launch their commercialization before marketing. This official launch of Iridium Certus is very important."

Desch said the broadband connectivity "life-security" of Iridium Certus for sea crews and riders. Iridium's new broadband bandwidth service will not compete hundreds or thousands of planned satellite mega-constellations aimed at the Ka-band and Ku-band consumer electronics markets.

"Iridium Certus is applicable to vertical vertical industry, from the sea and started in the mobile region and on the Internet of things", said Desche. "We are focusing on service life-long applications and the most prestigious high-bandwidth applications, we believe we are currently serving a 700 million dollar satellite service (Inmarsat), and we believe our service will be superior in all ways."

The Internet of Things is a period of time when it is a type of network that transmits data, measurements and other signals with a wide variety of objects around the world, critical shipments of road, sea or air travel.

"Iridium Certus is not designed to compete with high-speed satellite mega-constellations, or anyone using Ka, Ku, or other bands," said Desch. "Iridium Certus is complementary, for example, in marine applications today, L-band terminals have often been installed as VSAT (Ku- or Ka-band) airliner assistants for coverage and security."

Communications common L-band require a groundwater receiver smaller than Ku-or-Ka-band, and L-band rain, fog and storms are not interfered with, making it a critical service. But Ku and Ka-band offer a broader band than the L-band.

"Aviation applications, Iridium Certus, operating cockpit and security communications at an optimum level, will be the Ka- and Ku-band booth for everyone to use WiFi entertainment services," Desch said.

At an initial 388 million gauge orbit, the Iridium Next satellite will use its impulse to elevate 476 miles (780 kilometers) in height, in the orbit, where the first sixth block of the 1st block in the spacecraft will find six nuclei. Lower controllers in Leesburg, Virginia, the Iridium Network Operations Center, circulate traffic from the old, uninterrupted satellite service immediately, in a procedure called a "slot swap" procedure.

On the other Friday, four satellites are fleeing to the iridian fleet.

"This will make the new Iridium satellites in 75 orbit, and after a thorough analysis and validation process lasting several weeks, we will officially form a new constellation," Desche said.

Iridium satellites are turning off engineers, as new relay stations arrive in the orbit. Most older satellites have orbit maneuvers that fall into the Earth's atmosphere and will undergo a process called "passivization". Batteries and propellant tanks are drained and reduced as a result of an explosion. in the future

Iridium flares, a known phenomenon of heavenly observers over the past 20 years, will end when older satellites have retired. The Iridium satellites built in Lockheed Martin are like Teflon antennas covered with silver-covered mirrors, the sun's light reflects the sun before sunlight and after sunlight.

Slums can be predicted – the latter – and the short satellite becomes one of the brightest objects in the night sky. Sky-watching applications and websites can provide hours of iridescent explosives around the world.

The satellites designed by Iridium Thales Alenia Space have no other antenna forms that produce flares.

"Blare is a sad season of community observation," said Desche. "That will disappear."

Airships foreseen for North Atlantic air navigation trials

Aircraft managed monitoring service is also underway.

Aireon offers its services, including Harris Corp., built-in receivers, which integrate aircraft location data to ensure that air traffic controllers know about airplanes from the rest of the world, reducing blind flights to improved traffic and safety, and fuel efficiency.

Canadian, Irish, Italian, Danish and British air traffic authorities are part of the Ionium Aircompany, and air traffic management organizations are preparing to use the system in other African, United States and European countries.

"In addition to Iridium's next constellation, Aireon will receive real-time air traffic surveillance data, compared to terrestrial systems, but across the planet, oceans and remote areas have never existed," said Don Thoma, CEO of Aireon.

The air system includes data from aircraft emitted by ADS-B technology. Automatic dependency monitoring or ADS-B technology allows an aircraft to determine its location through satellite navigation and then immediately transmits it to the position.

This reduces resistance to air traffic control to keep track of aircraft movements in the old tracking radar. On the ground ADS-B receivers have the same limit as the radar; They do not continuously monitor airplanes in the oceans and in other remote regions.

When airplanes fly by radar, the pilots generally deal with the maintenance of infrastructure and heights, for the safety of the aircraft between 30-150 kilometers (50-150 kilometers). With real-time global monitoring, these requirements can be reassured.

Aerodrome receivers are designed to receive the same ADS-B signals provided by most airplanes in the next satellites per Iridium. U.S. and European regulators need a passenger plane with ADS-B technology by 2020.

"It was the main reason for airing," Thomak said. "For many years, it has been a clear and comprehensive system of aircraft surveillance, not only for air traffic management but also for the safety of those traveling on board.

"Aireon accepts important security improvements, eliminating the lack of monitoring of aviation distribution and the lack of security in the state of consciousness, by reducing the lack of security barriers in real time," said Thomak. "The response of the controllers will be reduced to normal times, such as weather deviations or navigation errors by riders, and, of course, improve search and rescue responses.

The use of air will improve the efficiency of air traffic through optimized flight paths and the improvement of traffic flows. In real time, airline companies will plan and fly more straightforward to save a large amount of fuel. "

According to Thoma, Aireon's system certification must be launched to allow operational trials on satellite-based ADS-B location data to begin in the North Atlantic in April in the open air corridor between North America and Europe.

The Canadian and British traffic authorities will oversee these trials, and the Federal Aviation Administration will attempt similar tests on the Caribbean.

"The final shot at Aireon is very significant," said Thomak. "The final delivery of 10 airplanes for the delivery of the aircraft will be definitively terminated on the Aeronautical Network, and once the airbags are integrated into the constellation, the engineers and triggers will perform the tests, with the final validation and certification, the operating system for air traffic control."
