Xona's satellites will use a similar signal, but one that's 100 times stronger, to offer greater resiliency against such deliberate interference. But the Pulsar-0 spacecraft also carries a GPS receiver to make sure the two systems will be able to work together. When the Xona team first turned on that receiver a few months after Pulsar-0's launch last year, they were shocked by the scale of signal degradation the receiver was reporting above Europe and parts of the Middle East.

Hello? Here are people living, on the planet known as Earth...
Are you sure it's safe to turn your machinery on "x100 times" of power?
Do you even care about human safety in these frequencies ever?

you need to learn about inverse square law.

Thank you for the reminder! Yes, I recall the law learned around two decades ago alongside the waveguides and reflectors.
And I'll try refreshing the knowledge with more time available.

The transmit power of these satellites is on the order of 200W, so 100x more would be 20kW, so about the same as a TV transmitter. And you can drive right past a TV transmitter, whereas satellites are thousands of miles away in space, and the received power here on earth is a fraction of the emitted power.

is signal strength just higher volume?

It's likely a higher amplitude, that is. In radio, normally, the electricity current.
Yes, it may be related to the sound signal volume indeed.

Yet, hardware or a human, as a recipient has limits in terms of amplitude, the current, and either ears may get damaged, or brain get fried, or worse, unfortunately.

Six men are likely to have been accidentally exposed to high levels of very high frequency (VHF) radiofrequency radiation (100 MHz) while working on transmission masts; four men in one incident and two in another.

Human cells die at about 107 degrees Fahrenheit or above, and when contact is made with a strong RF transmitting element the tissues near the point of contact rapidly heat well above this level. In severe cases this can cause an RF burn.

This is accurate. RF burn sucks but you've got to be touching a powerful transmitter, and pray you're not wearing jewelry.
