Wow, sounds great. So the dish moves, following one satellite, then another?

no, the dish is stationary (to my knowledge) after it finds its focal point.. I'm not entirely sure of the exact process after that, other than it involves using mutiple satellites, laser beams, ground stations and your dish.

We received the email from Starlink on Friday and we signed up. Should be arriving in 4 to 7 business days. Say goodby to Viasat and Directv.

Where abouts are you located? I'm curious to see the locations of all who are running the beta test for this? And I'll assume that once this goes live public release all of ID will be available? I've stumbled up some property around the southeast part of the state that has some interest from the wife.

We are just south of Sandpoint. it seems most of the beta tests were on the 44 to 41 parallel if I recall.

If you are curious how the antenna is steered/pointed at high speeds, here is a video from a guy who tore one apart last month. It shows that it is an electronically steered phased array. I would imagine it is generally pointed in the right direction when installed; then the system is activated and the electronics take over to perform the high speed beam aiming to track the satellites.

Such flat panel, phased array technology was developed decades ago, and used in military applications. The flat front of an Aegis cruiser contains a low band, electronically phased array, but there are a lot of other examples.

BTW: 'Beam steering' goes back prior to WWII; mechanically activated phase shifters were used to shape airborne radars on sub-hunter aircraft, so that the radar returns were better equalized for both near and far targets. And that phase shifting was derived from early phased antenna array used in commercial AM radio stations, as far back as the late 1920's! So these principles are old, but modern technology adapts them to new applications.a

Fascinating video. Thanks for sharing. I was a Radarman/Operations Specialist on the last cruisers with the older, rotating radar antennas and always wondered how phased array radars worked.

That Starlink is an amazing piece of engineering. Worth way more than the $500 price.

Ahah, an ETR! I was ETN during my stint in the USN. (Left the Navy, got my engineering degrees, and spent 15 years designing electronics for communications and radar, in the consumer, military, and cellular fieldss.)


The frequencies mentioned in that video, up in the 40-50 GHz range and higher, is quite a leap forward in technology that has come in less than the last 20 years and is pretty amazing that it is now being used like this.


If you like neat engineering graphs and data, here is something from the FCC from over 20 years ago about millimeter wave signal propagation. One of the things that can be seen is that heavy rain is going to have some effects on this system, just like other satellite services. If the system will have enough satellites in view at any time it might well be able to steer around a storm cell hanging in one part of the sky. I will be curious to see if other things like the fire smoke common out west in the late summer and fall, will have any impact; I have never read about satellite link losses in smoke.....
https://transition.fcc.gov/Bureaus/E...t70/oet70a.pdf


And for those contemplating this system, these super high, millimeter wave radio bands are pretty much 'line-of-sight' signals. So I suspect you need to have a 'window' to the sky that is decently sizeable for this for multiple satellites to be 'seen', which is a consideration if you have a lot of trees and/or are down in a deep valley. (A 'holler' as we call them here in the Appalachians...LOL) You will very probably need a bigger 'window' for the base station to look up through, compared to the 'window' needed for a standard dish system, which looks just at one spot in the sky all the time.

Starlink showed up Friday and hooked up. We had Viasat with 4 mgb and unable to stream anything.
Now with Starlink desktop gets 170 mgs and cell phone wifi about 140. Can't wait to use our house as a smart house after two years of it being a dumb house.
Thank you, Starlink.

Congrats, and looking forward to hearing the next update!

Hubby was just telling me about Starlink the other day. He's thinking it might be a viable option for working remote in an RV some day.
