SpaceX delayed last Wednesdays Starlink launch due to high winds and on Thursday they decided to do a software update and postpone the launch until next week, but they revealed significant progress in their Starlink mission press release and in tweets by and a media call with Elon Musk. The mission press release said SpaceX has significantly reduced the size and weight of their satellites. more
I've suggested that Cuba could use geostationary-orbit (GSO) satellite Internet service as a stopgap measure until they could afford to leapfrog over today's technology to next-generation infrastructure. They did not pick up on that stopgap suggestion, but how about low-Earth orbit (LEO) satellite Internet service as a next-generation solution? SpaceX, OneWeb, Boeing and others are working on LEO satellite Internet projects. more
In a study of the Internet in China in the late 1990s, my colleagues and I observed that "China has been able to execute plans effectively by allocating resources to competing, government-owned enterprises," and Kai-Fu Lee shows that they have pursued a similar strategy with respect to AI. Now they are doing the same with low-Earth orbit (LEO) broadband satellite constellations. more
SpaceX's Starlink project appears to be the only low-Earth orbit (LEO) satellite ISP among close to 400 ISPs to qualify to bid in a U.S. federal rural-broadband funding auction. more
We got a recent analysis of Starlink broadband speeds from Ookla, which gathers huge numbers of speed tests from across the country. The U.S. average download speeds on Starlink have improved over the last year, from an average of 65.72 Mbps in 1Q 2021 to 90.55 Mbps in 1Q 2022. But during that same timeframe, upload speeds got worse, dropping from an average of 16.29 Mbps in 1Q 2021 to 10.70 Mbps in 1Q 2022. more
When SpaceX first announced plans for Starlink, their low-Earth orbit Internet service constellation, they said each satellite would have five inter-satellite laser links (ISLLs) - two links to satellites in the same orbital plane, two to satellites in adjacent orbital planes, and one to a satellite in a crossing plane. They subsequently dropped the crossing link as too difficult and, when they finally began launching satellites, they had no laser links. Last year they tested ISLLs on two satellites. more
In a recent issue of the Dongfang Hour Newsletter, Blaine Curcio pointed out that China's powerful State Administration of Science, Technology, and Industry for National Defence (SASTIND) had published a notice intended to promote the orderly development of microsatellites and strengthen safety management. The notice defines microsatellites as being below 1,000 kilograms, which would include those making up China's planned GwoWang/SatNet broadband constellation. more
Sanjay Bhargava, Starlink Country Director for India at SpaceX (source)SpaceX Starlink is moving quickly in India. Last April, they said they would be offering service in 2022 and began accepting pre-orders. In July, SpaceX committed to manufacturing antenna systems and terminals in India and, at the end of September, Sanjay Bhargava, who had been with Elon Musk at Paypal, was selected to head Starlink in India. In the last week or two, they set up a wholly-owned subsidiary that will apply for licenses, seek Indian distribution partners, and attempt to sell 200,000 units - 80% in rural districts - in 2022. more
Beta testers in the US and Canada paid $500 for a terminal and are paying $99 per month for the service. The beta tests began in high-income countries, but SpaceX is beginning to roll Starlink out and will include low-income nations, for example, India. Last September, SpaceX responded to a request for consultation on a roadmap to promote broadband connectivity and enhanced broadband speed from TRAI, the Telecommunications Regulatory Authority of India. more
The bottom line is that success is not guaranteed, but neither is failure -- there is a non-zero probability of success. On May 26th, SpaceX applied for permission to launch 30,000 "second-generation" Starlink broadband Internet satellites. (Note that the software on Starlink satellites is updated about once a week). The application narrative states that the second-generation satellites will be configured... more
The new Biden Administration in the USA laid out a $100 billion proposal for broadband investment as part of its $2 trillion+ infrastructure plan. Under the proposal, the plan is to provide national broadband coverage. The Administration will use better competition measures, such as price transparency, the use of public utility infrastructure, and subsidies for low-income households to achieve its goals. more
Teledesic was the first company to plan to offer broadband connectivity using a constellation of low-earth-orbit (LEO) satellites. Craig McCaw, who had sold McCaw Cellular to AT&T, founded Teledesic in 1990 and it got a big visibility and credibility boost when Bill Gates made a small ($5 million) investment in the company. McCaw and Gates were able to attract capital - $200 million from a Saudi Prince, $750 million from Motorola, and $100 million from Boeing, which signed on as the prime contractor. more
On November 15th, Russia used an anti-satellite missile to destroy COSMOS 1408, a defunct spy satellite. The explosion quickly created over 1,500 pieces of trackable debris and will likely generate hundreds of thousands of smaller pieces. As a precautionary measure, the astronauts on the International Space Station, two of whom are Russians, took shelter in escape shuttles during two orbits. The anti-satellite test was widely criticized, but the Russian defense ministry released a statement saying... more
FCC has cast serious doubts about the capability of low-Earth orbit (LEO) satellite operators, such as SpaceX's Starlink, to provide low-latency broadband and thus their eligibility to bid. more
In his January 12 SpaceX update, Elon Musk said the biggest goal for Starlink from a technical standpoint is to get the mean latency below 20 ms. He expanded by saying that given the speed of light, 8 ms is the absolute minimum latency for a satellite at 550 km. He believes they can optimize terrestrial and inter-satellite links, and minimize queueing delays and dropped packets, to recude the the rest of the time to below 10 ms. more
