In 2017, Telesat, an established Canadian geostationary satellite operator, announced a planned low-Earth orbit Internet service constellation. The plan called for 117 satellites with inter-satellite laser links in a mix of inclined and polar orbits, enabling global coverage. more
SpaceX and T-Mobile are set to begin testing their satellite-to-cell service this year, an executive of Elon Musk's company confirmed Monday. Jonathan Hofeller, SpaceX vice president of Starlink Enterprise Sales, made the announcement during a panel at the Satellite 2023 conference in Washington, D.C. more
On February 2, 1989, the Soviet Union launched its Cosmos 2004 satellite and the Chinese launched a rocket on December 15, 2009. Cosmos 2004 is now defunct, as is the third stage of that Chinese rocket, but both remain in orbit. They were long forgotten until recently when LeoLabs, a satellite tracking service, predicted that they had a good chance of colliding at 971 km over the sea near Antarctica. more
There was a paper published in June in the peer-reviewed Geophysical Research Letters titled Potential Ozone Depletion from Satellite Demise During Atmospheric Reentry in the Era of Mega-Constellations. As can be deduced by the lengthy title, scientists have uncovered a new risk coming from the reentry of low-orbit satellites through the atmosphere. more
Iran has imposed a sweeping internet blackout amid nationwide protests, disrupting even Starlink satellite service. The move marks a new level of digital repression, raising fears of an impending crackdown shielded from global view. more
This week SpaceX petitioned the FCC to reconfigure their Starlink constellation and Elon Musk outlined their beta testing plan. As shown below, the most significant configuration change is reducing the altitude of four of the five groups of orbital planes by around 50%. The total number of satellites and the number orbiting at a 53-degree inclination, which gives good coverage over relatively affluent regions, are not changed very much. more
Last April, Elon Musk tweeted that Starlink "should be fully mobile later this year, so you can move it anywhere or use it on an RV or truck in motion." It is good to know that mobility with a standard dish is in the works, but it's not yet available. David Lang had been able to connect his Starlink terminal about fifteen miles from his home in Simi Valley, California, but when he brought it to my place in Carpinteria, California, about forty-three miles away and in a different coverage cell, it failed to connect. more
Following the devastating impact of Hurricane Helene on North Carolina, the U.S. Federal Communications Commission (FCC) has approved SpaceX's Starlink to provide direct-to-cell coverage in affected regions. more
When we first heard of the possibility of broadband from low-orbit satellites, there was a lot of speculation that the technology could bring affordable broadband to the masses around the globe. The latest announcement from Starlink shows that affordable broadband is probably not coming in the immediate future. Starlink announced a premium tier of service with a $500 monthly fee for 150-500 Mbps. more
After several delays due to bad weather, Amazon's Project Kuiper finally launched its first batch of low-orbit broadband satellites on April 28. The company says it is in communication with all 27 new satellites. Amazon used a United Launch Alliance (ULA) Atlas V rocket launched from Cape Canaveral. Amazon is under pressure to get the launches going and has a commitment to the FCC to launch 1,618 satellites by July 2026. more
On August 10, the FCC issued a press release denying the long-form applications of Starlink and LTD Broadband in the RDOF reverse auction. This is big news because these are two of the biggest winners of the reverse auction. LTD Broadband was the largest winner of the auctions at $1.32 billion, while Starlink had claimed over $885 million in the auction. more
The posting with a similar name seems a bit contrived by anonymous in some strange attempt to enhance its significance. Many others, including myself, have been discussing this subject for some time. Indeed, a concerted lobbying effort and anti-competitive efforts by legacy TCP/IP internet stakeholders have been really ramped up over the past year to mischaracterize what is occurring. more
Five companies are developing low-Earth orbit (LEO) broadband satellite constellations, but, as of now, only SpaceX is planning to market directly to consumers. What sorts of support will they require? A pilot study of Starlink connectivity in remote Chilean communities may provide some answers to that question. The Chilean regulator, SUBTEL, has authorized a year-long pilot study of Starlink connectivity in remote, rural communities and is committed to supporting them during the year. more
There was an interesting phenomenon that happened in September when Starlink launched 49 new satellites. The satellites were successfully deployed by the rocket, but as the satellites were being maneuvered to reach the final orbital slots, there was a geomagnetic storm that caused 38 of the satellites to fall back to earth. Space storms happen when radiation affects the magnetosphere that surrounds the earth. more
Every second, 4.5 billion people using computers and other electronic devices send 100,000 gigabytes of information to each other. Around 60% of the world's population has an Internet connection. North America and Europe have penetrations of 95% and 87%. But Asia and Africa do not yet get beyond 54% and 40%. On those continents, there are many remote areas where there is no Internet yet. At least no affordable Internet. more
