Starlink Status April 2022 mit ~2,110 Satelliten ohne Sat-to-Sat Laser communication => ~60 ms RTT

Im Vergleich zu
Fibre ~21 ms
Geostat Sat. ~650 ms

Ja, zumeist den billigen Tarif als Backupleitung. Mit dem Business Tarif hast du deutlich mehr Bandbreite, Latenzen sind die selben.

Zitat
SpaceX's laser system for Starlink is delivering over 42 petabytes of data for customers per day, an engineer revealed today. That translates into 42 million gigabytes.

“We're passing over terabits per second [of data] every day across 9,000 lasers,” SpaceX engineer Travis Brashears said today at SPIE Photonics West, an event in San Francisco focused on the latest advancements in optics and light. "We actually serve over lasers all of our users on Starlink at a given time in like a two-hour window.”

Although Starlink uses radio waves to beam high-speed internet to customers, SpaceX has also been outfitting the company’s satellites with a “laser link” system to help drive down latency and improve the system's global coverage. The lasers, which can sustain a 100Gbps connection per link, are especially crucial to helping the satellites fetch data when no SpaceX ground station is near, like over the ocean or Antarctic. Instead, the satellite can transmit the data to and from another Starlink satellite in Earth’s orbit, forming a mesh network in space.

Tuesday’s talk from Brashears revealed the laser system is quite robust, even as the equipment is flying onboard thousands of Starlink satellites constantly circling the Earth. Despite the technical challenges, the company has achieved a laser “link uptime” at over 99%.

The satellites are constantly forming laser links, resulting in about 266,141 “laser acquisitions” per day, according to Brashears' presentation. But in some cases, the links can also be maintained for weeks at a time, and even reach transmission rates at up to 200Gbps.

interesting, wusste garnicht dass die laser-links zwischen den sats überhaupt schon funktionieren... dachte das kommt erst mit v2 der satelliten

da geht ja ordentlich was weiter :cool:

Das ist eh ein gutes Feature von Starlink und hoffentlich auch den anderen Sat-Providern.
Sonst wäre da oben bald alles zugemüllt.

das waren alles v2mini (damit es sich in der falcon9 fairing ausgeht)

v2 ist ja dafür designed im starship via pez disposer rausgeworfen zu werden, afaik
