So to recap, J-man says it's either god bounces off of the dome or balloons and Junker says to read the Wiki for GPS information where none exists.
Very informative.
Yep. If you search the Wiki for "GPS" you get exactly one page: https://wiki.tfes.org/Space_Travel - which contains four broken links and nothing else.
If there was just one GPS system and it only worked in continental USA, then towers and balloons and such might work - but there are AT LEAST four different GPS-like systems out there (US, Russian, Chinese and European) and all four of them have world-wide coverage. Do you see Chinese and Russian navigational towers studding the landscape in the USA? Are there thousands of balloons from all four nations drifting languidly across our skies?
The "bouncing off of the ionosphere" approach cannot work for precision better than a few kilometers - and all four systems that we know of are accurate to within ten meters or so most of the time.
So I guess the Earth must be round.
qeek you should stop the deceit or maybe it's just ignorance? TV GPS radar all work off High Frequency waves now. You don't need satellites for Skywave, Groundwave or Line of Sight transmissions. Put the Kool-aid down and come join us in this brave new world that was discovered in 1921....
https://en.wikipedia.org/wiki/Skywave"In radio communication, skywave or skip refers to the propagation of radio waves reflected or refracted back toward Earth from the ionosphere, an electrically charged layer of the upper atmosphere. Since it is not limited by the curvature of the Earth, skywave propagation can be used to communicate beyond the horizon, at
intercontinental distances."
"E-skip is a notable exception, where VHF signals including FM broadcast and VHF TV signals are frequently reflected to the Earth during late Spring and early Summer."

Abstract: Written by a leading global expert on the topic, High Frequency Over-the-Horizon Radar provides in-depth coverage of the signal processing models and techniques that have significantly advanced OTH radar technology.
Conventional Processing
"1010505Signal and data processing have long been recognized as key elements to the success of OTH radar (Headrick and Skolnik, 1974). Such systems are inherently required to operate in severe clutter, interference, and noise environments, where the power of a received target echo is typically several orders of magnitude lower than that of the disturbance signal. Here, signal processing refers to a sequence of steps that transform the in-phase and quadrature baseband data samples acquired by the analog-to-digital (A/D) converters in each receiver of a multi-channel system to complex-valued outputs in the canonical radar dimensions of group-range, beam direction, and Doppler frequency.

The Israeli's invented Voice over internet Protocol which is in fact the basis for the success of this HF model. To take analog packets smash them down to digital packets with individual ID and blow them all over the skies. Then suck them up with a huge vacuum cleaner, they automatically arrange in the proper order and a high tech switch is able to then send them (packets) to the processor to find your ass, listen in on ya, or send you reruns of Little House on the Prairie.
The storage facility in Utah to accumulate every digital packet ever processed is waiting for you. There is no escape.
