India frees itself from the US & Russian GPS system.

Back home, the mission control room of Indian Space Research Organisation(ISRO) resonated with thunderous applause. The scientists who were till then glued to their monitors burst into cheers. India’s mini GPS, a regional positioning system, was ready to be rolled out.

Prime minister Narendra Modi who was watching the launch live from his office in Delhi congratulated the scientists. “With this successful launch, we will determine our own paths powered by our technology. This is an example of made in India and made for Indians,” he said. The navigational structure was given a new name — NavIC (Navigation Indian Constellation) — by the prime minister. “125 crore Indians have got a new Navic,” he tweeted.

Desi GPS The seven-satellite constellation, IRNSS (Indian Regional Navigation Satellite System), is designed to provide a regional positioning system for India with the least number of satellites. It is expected to provide accurate position information service to users in India and 1,500 km around the Indian mainland.

Hmmm; I guess the government needs to change its mode of operations. I believe that everyone has been saying this for a while now.

Technology companies are moving too fast for governments to keep up, according to a former chief of the US Defense Advanced Research Projects Agency (DARPA).

Kaigham (Ken) Gabriel was acting director of DARPA and the man behind drone technology and global positioning satellites, as well as the military’s top secret, high-tech operation responsible for inventing the forerunner to the internet, Arpanet.

He believes governments are fighting a losing battle with technologies such as encryption. But, when it comes to the possibility of advanced tech falling into the wrong hands, he doesn’t believe western governments should give up altogether.

DARPA plans to service orbiting satellites.Satellites operators have been longing for it for decades, and DARPA (once again?) is turning their dream into reality: on March 25, one of America’s most futuristic agency announced it would launch a public-private partnership to provide in-orbit servicing to geosynchronous satellites, both commercial and military.

The program dubbed Robotic Servicing of Geosynchronous Satellites (RSGS) will be a major breakthrough for the satellite industry world. Since Sputnik’s launch, the biggest weakness of satellites was that, once on orbit, nothing could be done if something went wrong or once the fuel tank ran dry. A rather embarrassing issue when considering how pricey such platforms are. The only maintenance and repair operations performed to date were manned (Hubble telescope, ISS). The agency announced that it would allocate RSGS $500mn over the next few years, supplemented by commercial partner investment.

DARPA’s RSGS is composed of two elements: the arm that will dock and manipulate the satellite, and the space ship carrying it. Regarding the first element, the agency will provide its Front-end Robotics Enabling Near-term Demonstration (FREND) technology. The prototype of the FREND arm was built for the agency by the California-based company Alliance Space Systems. The robotic arm will enable it to dock with satellites and carry out maintenance.

“The station regularly passes out of range of the Tracking and Relay Data Satellites (TDRS) used to send and receive video, voice and telemetry from the station,” a spokesperson for NASA told ValueWalk.

The only problem with this explanation, of course, is that it’s so much more boring…”

It is, of course, highly unlikely that this was some alien ship. That said, those tracking and relay stations are fixed and known locations. Also, the range and power of the ISS communication systems are well known, non-classified public domain knowledge. I suck at math, but it should only be a matter of taking the exact time and duration of this outage and comparing it to the tracking and relay station stats.

Although Google has been filing patents for the design of an advanced high-altitude balloon network for some time now (examples one and two) and CEO Larry Page talking up Project Loon with Charlie Rose at a TED Conference, it appears that they’re simultaneously dreaming of another Moon Shot project related to a communications satellite constellation wrapped around the globe.

In 2014 Google signed a 60 year lease with NASA airfield and hangers. The Verge reported at that time that “Google may use Hangar One, as well as two sequentially named hangars on the airfield, as a space for research, development, assembly, and testing of technology related to robotics, aviation, space exploration, and other new fields once it moves in. Perhaps Google’s recent patent application discovered at the US Patent Office for a new satellite constellation is one of the many projects that they have on their drawing board.

Google’s patent FIG. 1B noted below shows us a schematic view of exemplary orbital paths or trajectories of the satellites in their proposed system.

SpaceX has finally landed its Falcon 9 rocket on a drone ship at sea, after launching the vehicle into space this afternoon. It’s the first time the company has been able to pull off an ocean landing, after four previous attempts ended in failure. Today’s success is a crucial milestone for SpaceX, as it shows the company can land its rockets both on solid ground and ocean.

This is the second time SpaceX has successfully landed one of its rockets post-launch; the first time was in December, when the company’s Falcon 9 rocket touched down at a ground-based landing site in Cape Canaveral, Florida, after putting a satellite into space. Now that SpaceX has demonstrated it can do both types of landings, the company can potentially recover and reuse even more rockets in the future. And that could mean much greater cost savings for SpaceX.

Mastering the ocean landing is going to be important, since that’s the type of landing SpaceX will probably conduct more often. At a recent NASA press conference, Hans Koenigsmann, vice president of mission assurance for SpaceX, said the next two to three flights will involve drone ship landings. Ultimately, the company expects to land one-third of its rockets on land, and the rest at sea.

Satellite manufacturing today is a lengthy, meticulous process; its high tech nature, and the cost in time and money make advances slow compared to sectors like the mobile industry. But an explosion in demand for connectivity and other space services is driving the need for ever-more capable satellites. It is at this crossroads, that bold new ideas are being forged.

Next week, astronauts on the International Space Station are getting a brand new room. Called the BEAM, short for Bigelow Expandable Activity Module, the room is launching on top of one of SpaceX’s rockets on Friday; it will then be attached to the ISS sometime within the next four months. The BEAM, which is created by private company Bigelow Aerospace, will remain deflated during launch, but once in orbit, it will inflate up to four times its size, providing more overall volume for the interior of the ISS.

The BEAM isn’t a permanent addition to the space station, though. It will only stay attached to the ISS for two years, and the astronauts will go inside the habitat very rarely. That’s because the main goal of the BEAM is to test out if this expandable habitat technology actually works. A successful mission could be the first step to something bigger: an era when expandable space habitats orbit the Earth, allowing for scientists and tourists to visit these “space hotels.”

The concept of expandable spacecraft isn’t new. In the 1960s, NASA launched a series of expandable communication probes called the Echo satellites, which looked like big metallic balloons. The satellites inflated in space and turned into mirror-like reflectors that bounced signals from one spot on Earth to another. Since then, NASA and other private companies have toyed with the idea of scaling up expandable spacecraft so that they could house humans in space.
