Flat Earth General / Re: Jane's FE Compendium
« on: February 12, 2019, 03:58:00 PM »

This is a little outside the usual wheelhouse for this thread, as it's not exactly a principle specific to FE models and this isn't intended to answer every question asked of FET, but there are a few interesting concepts used so it seemed worth a mention.
First, as ever this is not universal. There are FE models (like the non-Euclidean) that allow for conventional space travel. Beyond that however, what fills the roles of satellites if there is no space travel? This question can especially be asked when there is no clear means for a perpetual orbit.

The catch-all term here is stratellites, which are literally just in-atmosphere equivalents. Commonly these are posited to be anything from planes, airships, balloons... though there are models (such as AFET) that have an alternate explanation for gravity that can be cancelled in certain circumstances allowing for machines that we have no real existing name for that can stay aloft easily. More conventionally, there can also be communication towers with either a direct line of sight, or a signal bounced off the upper atmosphere.
This allows for signals to be transmitted.

These can also be used to simulate points higher up. A satellite dish pointed one way could receive a signal from anything along that line, no matter how far it is. Two dishes claimed to be pointed to the same satellite are not necessarily doing so. This kind of simulation is connected to the GPS question; at a basic level GPS functions by a receiver picking up a signal from a transmitter containing the time at which the signal was sent, which is then used to determine how far away the transmitter is. With multiple transmitters, this ends up providing enough information to find a location as there will only be one spot that is the known distance away from the various points.
If a stratellite staggers the signals it emits, it can give the mathematical equivalent of a signal sent from higher up, at least if the signals are more directional.

For an example, forgoing units so we don't have to be constrained to realism, in the RE model a person on the ground might have a GPS transmitter telling them that they are 10 away from satellite A, and 12 away from satellite B.
In the FE model, stratellite A would be 5 away from the person in question. To compensate, the signal it emits is delayed; it gives the signal it itself would receive if there was a satellite A 5 away from it. Thus it creates the illusion of a satellite at higher altitude. A transmitter would still receive the 10, but this is just because the stratellite is giving data staggered as though it had already gone a distance of 5, only for it to go another 5. The same holds for stratellite B.

With this principle, GPS essentially functions as a landmark system. If you are a known distance away from a known point, it naturally gives an accurate reading of where you are. This is true independently of whatever world map is programmed into the receivers; any error that would creep into a journey based on differences between a flat and round map would, on the comparatively small scales of normal journeys, be put down to typical error just from the process of travelling and immediately be corrected for by locating another known point of a stratellite.
Slight problem with the GPS delay system.  Has to work for multiple users and there is no communication back to the transmitter to derermine the delay.  And not just distance, it's the angle that gives the position.  And a reciever can 'see' about 20 transmitters to get an accurate reading.  Apart from that...

Flat Earth Debate / GPS Requires Satellites
« on: January 11, 2019, 12:03:16 PM »
Let's start!

GPS Requires Satellites
GPS does not require satellites to function. It uses very accurate clocks.

We agree the clocks are accurate.  We have to be careful about the use of the word 'requires' when we should use the word 'uses'.

Receivers give the location of each satellite they are receiving from, can be up to 20 with the various system from US, Russia, Europe etc.  Reception is consistent with there not being ground based transmitters.  Particularly Russian ones in the US!

Similarly satellite TV dishes point to locations over the equator consistent with globe calculations.

Flat Earth Debate / Undersea Cables

This gives details.

When they lay cables they calculate the lengths based on a round earth.

Or do they find they have too much or not enough cable?

Question for you, do they exist, how do they work?

Flat Earth Q&A / How does Satellite TV Work?
« on: February 26, 2014, 06:51:06 AM »
This replaces any discussion of the subject elsewhere.

a) Receiving from a geostationary satellite over the equator in the home.  Noting that south facing dishes on the south coast of countries in the northern hemisphere work

b) TV trucks transmitting live pictures from remote locations back to the studio.

We know dishes have to very accurately aligned to work and the setup angles fit in with the calculations for the satellite location.


jroa - how about you explain how TV links work instead of saying everyone is wrong.

Flat Earth General / Fly to the South Pole
« on: February 07, 2014, 02:23:58 AM »

Fly by private jet to the Antarctic interior and Adventure Network Internationals base camp at the foot of the Ellsworth Mountains, 600 miles from the South Pole.

Fly in specially equipped ski aircraft to the geographical South Pole. A journey that will cover 600 miles across wind swept terrain and sastrugi and last approximately 4-5 hours.

Reach the geographic South Pole and the realization that you are now standing at the most southerly point on earth where, beneath your feet, all 360 lines of longitude collide and the ice is almost 3 000 m (10 000 ft) thick.

Flat Earth Debate / GPS
« on: December 13, 2013, 11:58:53 AM »
A car GPS receiver will show the bearing, ID number and signal strength of typically 10 satellites.  If the vehicle is stationary these will move over time.

How is this explained?

For info for some - geostationary satellites orbit above the equator at a height for a 24 hour orbit, GPS ones are lower and not fixed to be above the equator.

Where can I find a map of the FE?
