The 2x2 phased array is tracking satellites! I am running some tests on LEO satellites before I go full electronic beam-steering. #AMSAT #N4IP #SO50 #RS44 @RFSPACE

@rfspace Can you link to the phase shifter design?

@rfspace The goal is to have an SDR phase shifter with 16 channel ADC and a 420-450 MHz front end for each ADC.

🌍 At the World Space Business Week in Paris, our President Scott Wisniewski joined a panel on Direct-to-Device Satellites. Scott highlighted our MNO-first approach and comprehensive spectrum strategy: “Having a large aperture in low Earth orbit lets us handle more frequencies, balance cellular and MSS strategies, manage multiple frequencies within the same beam, and deliver as much service as possible. We don’t require a new device — it’s about enabling a full offering with flexible technology and spectrum strategy through an ecosystem approach.” 🚀 With the largest commercial phased-array satellites in LEO, flexible technology, and strong MNO partnerships, and we are building the future of global connectivity. #WSBW #Satellite #Connectivity #D2D #ASTSpaceMobile

Have you ever wondered how Starlink can keep talking to satellites moving across the sky? It uses a Phased-Array Antenna. It has many small antenna elements on a flat surface, and each one is given a tiny phase delay so the radio wave adds up in one chosen direction. That lets the beam steer electronically and stay locked onto a fast-moving satellite. In this animation, the beam pattern was generated using computational electromagnetics, by computing how the array’s directional pattern changes as those phases are updated.

SpaceX has released an updated Starlink Mobile website, along with a new video and coverage map that shows where the service is currently available and where it's coming soon. Starlink Mobile: • Available on 40+ apps and on 100+ devices. Future service will offer video calls, streaming, emails and more. • 32+ countries (covering 1.7+ billion people) • The next generation of Starlink Mobile satellites - V2 - will deliver full cellular coverage to "places never thought possible via the highest performing satellite-to-mobile network ever built." • V2 Starlink Mobile satellites will use custom SpaceX-designed silicon and phased array antennas. The satellites will support thousands of spatial beams and higher bandwidth capability, enabling around 20x the throughput capability as compared to a first-generation satellite. • V2 will enable full 5G cellular connectivity with a comparable experience to current terrestrial service.

This house - where Heidi and I built our life together, and brought our sons home from the hospital - is imprinted on my brain and in my soul. I go to my dirt lot every day because I am connected to this place. And as much as I am connected here, I am also connected to the City of Los Angeles. And I’m running to save it before it all turns to ashes. Watch the full episode of IMPACT by Nightline 's “Hated on The Hills: Spencer Pratt Rewritten” on Hulu. #ImpactOnHulu ABC News Studios

THE PATH TO 100 TERAWATTS GOES THROUGH THE MOON "If you want to go up another order of magnitude let's say you want to go to 100 terawatts a year which is obviously a nutty number then you want to make those AI satellites on the moon and use a mass driver Like Robert Heinlein’s The Moon Is a Harsh Mistress. I love that book; it’s a sort of libertarian paradise on the moon On the moon, you can just accelerate the satellites into escape velocities around 2,400 meters per second and there's no atmosphere, so a mass driver works perfectly"

The $100 CNC I got on Facebook marketplace seems to be working just fine. Next up is running some G code and making my first cut! I also need to add some limit switches before I inevitably crash this thing.

"It's nice to do something before Elon Musk for once." Rocket Lab CEO Peter Beck on the benefits of going public: "I didn't want to build a space company that just lives for the lifetime that I'm running it. It needed to be multi-generational & go on & on & on." "And being a public company really enforces that discipline of profitability‚ & profitability is survival. The rockets & satellites, it's all cool, but at the end of the day, it's all for nothing if your economics aren't there & you're not profitable."

#WATCH | Raipur, Chhattisgarh: Mahima Rajput, a 10th-class student, is selected for the international space Mission 'ShakthiSAT' from India. Students from 108 countries will participate. Mahima Rajput says, "I am selected for the Mission 'ShakthiSAT', which my principal told my guidance teacher, and she registered me after that. After I registered, some modules came up, which clarified your basic concepts about science and satellites. There were a total of 21 modules and 365 lessons, which helped us a lot. We were trained in how to make satellites, which includes a total of 108 countries. On the 23rd of August, we have to go to Delhi, where we will build a satellite that will land on the surface of the Moon, and another satellite will revolve in the Moon's orbit, and then we will launch it in October..."

This is Balochistan's Ras Koh, where Pakistan conducted its nuclear tests, NOT the Chagai Hills. ​The famous peak that turned white on May 28, 1998, is Koh Kambaran, right here in our majestic Ras Koh Hills. ​The actual Chagai Hills run along the Afghan border, 100km further north. While "Chagai-I" was the military's clever decoy name to keep international satellites guessing, the actual mountains that made history belong to Ras Koh. ​#Balochistan #RasKoh #Chagai
