There's a number of proven tools used to navigate this planet as per RE.
I'd like to see FET list their tools and explain how they work.
To start with I'll list a few RE tools we can brake down how they work and/or FET can can explain why they don't work.
#1 Dutch Pendulum Clock. In the 17th century
#2 Ramsden Sextant. Navigating in the sea. 18th century
#3 Apollo Sextant and Scanning Telescope. Navigating in space. ( While this instrument does not look like a traditional sextant, the basic procedure is descended from centuries-old methods used by navigators at sea and in the air.)
#4 Longines Sidereal Second-Setting Watch. Before 1927, watches used with sextants for celestial sightings could only be set to the minute. A watch error of 30 seconds caused a navigational error of up to 12 kilometers (7 miles).
#5 Lockheed Vega 5C Winnie Mae. Wiley Post's Winnie Mae circled the globe two times, shattering previous records. The first time was in 1931 with Weems associate Harold Gatty as lead navigator. The second was a solo flight in 1933 assisted by "Mechanical Mike," one of the world's first practical autopilots.

Anybody that's experienced in navigation I would like to hear their stories, RE and FE alike.

"Believe it or not, the SR-71 used a computerized celestial navigation system as one of its primary means of navigating the globe. The system could lock onto as many as 11 stars at a time, even during the day, and could determine the jet's position with up to 300 feet of accuracy. That's not a bad thing to have when you're going Mach 3."
"OMEGA became operational in 1971, and was the first global radio navigation system. It enabled aircraft to navigate using low frequency radio signals transmitted from 8 OMEGA antennas placed around the globe. The OMEGA system was shut down in 1997 because of the widespread use of GPS, but one of its stations in La Moure, ND, was converted to a US Navy submarine communication station."
"Loran-C gained popularity in the 1970s. It used a network of land-based radio beacons to create a highly accurate, long-range navigation system. But its fate was sealed by GPS. While Loran-C is still operated, many stations around the world have been shut down, or are the process of being decommissioned."
"Without GPS, we wouldn't be going 'Direct To' many places. The first production GPS satellite was launched in 1989, and the 24th satellite was launched in 1994, making it the first full-global satellite navigation system."

Hmmm several references to GPS and Global. Flat Earthers won't like that.. global suggesting round, spherical etc
I thought Flat Earthers are convinced that nothing has ever gone beyond the Earths atmosphere. If so (and I stand to be corrected if I'm wrong) then presumably Flat Earthers will not believe the GPS system exists. Or is it just that they think no human has ever gone beyond the Earth?

I could be wrong but I think the FE belief is that GPS uses towers not satellites.

Fair comment I suppose. For towers though it would have to work by line of sight surely and that poses a bit of a problem to me out in the middle of the ocean. My telescope has got a GPS receiver which locks onto up to 20 'satellites' in order to obtain a location, time and altitude reading. It also tells me by digital display exactly where the satellites it has locked onto are in the sky. That would be a problem if towers were used.

I think they claim you're are locking onto balloons. Satellites are a hoax perpetrated by NASA

The most important requirement for navigation is a map.
You can't navigate without maps.
I see myriads for globe earth, none for flat earth.

Of course why didn't I think of that! Are the ballooons in question anchored to the surface somehow or are they free floating? I suppose in theory you could make anything up to try and avoid having to admit the obvious couldn't you. That seems to be a particular talent among the FE people.

There's threads here about satellites being hoax. Interestingly a few comments directed at flatearthers that they should admit the obvious and come up with a new theory that makes satellites fit in the flat earth model.
RonJ, a member here, a career seaman merchant marine, cargo ships etc. Somewhat of an authority on the subject, explained thoroughly how satellite navigation at see works. Of course FET argued with him that he was getting radio signals from land based antenna networks. He explained how he had to pint the ships antennas up in the sky directed at the coordinates provided by the satellite companies. Also how he would have to switch to another satellite when the one in use would drop below the horizon of the curvature of the Earth.
Pretty interesting stuff.
He also pointed out how expensive these systems were and that if FET were correct the shipping industry as well as many other could save a lot of money if they could use line of sight radio signals.
-
Absolutely. The TV and mobile phone industries to name just two who spend a LOT of money on the technology needed to beam radio signals off satellites in order to give us phone and TV signals all over the world. I'm sure they would be very impressed if suddenly they realised that money hadn't needed to be spent!

It would definitely be a lot cheaper to set up a series of low powered short antenna network stations than the billions of $$s it takes to design, engineer, manufacture satellites, launch vehicles, the total sales industry and tech support, field crew etc. etc. of satellite networking.
Interesting how GPS works for navigation. I have a unit on my motorcycle called Garmen, basically a GPS linked navigation system.
I give readout on the digital screen speed, mileage, altitude, air temp, warnings of traffic delays, weather, just a number of things.
Interestingly the GPS speed calculator is accurate to every road side radar speed indicator, where my speedometer is off 5 mph. Also miles traveled is off on the trip meters that match the speedometer. But the GPS miles traveled is accurate to map calculations.
An example of how accurate GPS is is I got a ticket going 80 mph as per the cops radar and my GPS but when I looked at the speedo when I saw the cop it read 85.
When the the technician comes up on the mountain to adjust my satellite dish he goes through a series of tests to find the bird in the sky above and beyond any mountain tops. Another indication that the signal is not coming from as radio tower. Also that it's a fixed position that never changes. The idea of FET, a balloon in the sky would work if it were tethered to the Earth.But then you would see the tether and thus have proof. There is non. Another fallacy in FET.
I think Tom said something to the effect that Speedometers are accurate and GPS is off.
I mentioned if you search Speedometer error % allowed especially you'll find that to be 5% to 10% nation wide. I got no response.
Just like everything else when flat earth believers claims get flattened they disappear.
