The large constellation is to allow connectivity only, much like access points. Alot of them are needed to cover the large geographical area. Each starlink satellite has a finite footprint on the earth it can service because the angles and distances make the connection unstable.
Starlink does NOT host web services and systems in space other than the access point (and future cell service via tmobile). So you still need to downlink to earth for access to connected systems and services. There are many downlinks and the system can transfer connections via satellite to a better downlink location. But you still need the earth's internet.
Regarding the hope that government and private business are prepared.. they like to say they are but the reality is somewhere around the dunning-krueger-esc "we are prepared" to "were working on it".
The problem here is its all simulations, nothing real. The last real nuke test for emp was just before the airburst treaty went into effect and the blast pegged all the measuring equipment.
We don't know what we don't know. Be prepared for life without...
Thanks for the clarification. My prior experience was some exposure to the Teledesic project, operating with an antenna footprint of 700 km2. These footprints move along at orbital speed (~7.8 km/sec for low Earth orbit), so dwell times are probably measured in a matter of a few minutes at most. There will be considerable packet switching to connect with a ground terminal.
I looked up Starlink to get some sense of the downlink distribution and support and it is pretty amazing. A complete terminal is priced to be available to commercial or industrial entities. A lesser capability is potentially available to those who can afford it, so links direct to user may not be far off at all. It was a quick scan of a long article, but it seems that the system relies on wifi for the final path to the end user, instead of landline.
The government apparently issued a response strategy in 2018, so, yeah, they're "working on it."
Were you thinking of the Starfish Prime test in 1962? There is plenty of theoretical dissection of what happened, based also on a similar Soviet test that same year. Underground tests still provided data on nuclear detonations, and we've also learned more about the structure of the upper atmosphere since then.
Yea the whole fishbowl project really. From the models devised from those experiments they have extrapolated what "could or should" happen regarding emp, but its all just models.
I tend to think that the starlink satellites would be greatly affected as well. In private discussion with starlink design engineers they give zero confidence in survivability of the local constellation above a blast.
