Does this mean curtains for the most dangerous weapon in the US Army inventory?

A 2nd Lieutenant with a map.

It is one of the things I immediately thought of when considering starlink.

It also hardens military communications (potentially all communications).

Teach them navigation with a map and compass and jamming isn’t a problem.

My car has gps but my old Harley doesn’t. Both the Harley and the car have a map and a compass, and that’s what I use.

It takes a certain type of intelligence

to understand maps and to use compasses well.

Substantial numbers of people are not up to it.

I suspect the number of people who can do it well is less than 20%.

Wonder if that’s the main goal, (or if the main goal is even more spooky and still hidden) rather than a by-product.
Kinda like Howard Hughes and the Glomar Explorer...

Looking for “manganese nodules”, instead of actually grabbing a sunken soviet sub.

I would be more inclined to go for it

As if it matters whether you go for it or not.

I have Starlink in my Subara. Is this the same Starlink or something different?

Britain bought a company that went bankrupt in the midst of launching a smaller constellation of about 1,300 LEO satellites. Britain was severed from participation of the European version of GPS known as Galileo, due to the Brexit vote. As this is not a completely new concept, perhaps this is their compensating move.

P.S.
Some sources state that a StarLink satellite runs algorithms which provides for self-knowledge of position to centimeter accuracy. This could confer an operational advantage, considering that a laser interlink is intended for node-to-node bucket brigade style relay of coms traffic about the globe—pointing accuracy. Reduced chance of intercept.

The U.S.military already uses the Iridium satellite network for high integrity jam resistant GPS under the name of IGPS. The Iridium signal is upwards of a million times stronger at ground level. The I birds transmit the full GPS almanac and orbital parameters in less than a minute compared to 12 with GPS. In addition to also transmitting a CDMA time epoch signal that’s encrypted that is used a a pseudo GPS satellite adding 60+ more usable signals to the IGPS enabled receiver. IGPS is also capable of using the older Transit Doppler effect navigation method due to the low earth orbits of the iridium birds , only a single signal from a single iridium birds is needed for a Doppler transit fix. The actual transit system was not retired until 1997 having served as the sole sat nav system for the Navy since the 1960s. Starlink can and almost assuredly will also transmit GPS almanac data and a CDMA time signal from each of an expected 30,000 birds with dozens visible at once at lower levels in the spot beams well over a million times stronger than GPS. A system of such magnitude will be for all purposes unjammable as one birds will always be visible in a beam formed null of a military grade active antenna system. Military units have phased array antenna with active beam steering any ground based hammer will simply be nulled as the antenna points it’s beam upwards to one of thousands of satellites all broadcasting a high integrity jam resistant GPS signal with low earth orbit Doppler shift allowing single bird convergence of the least sums Taylor matrix fix.
