This thread made me join. haha.
Good question OP. I'm a communications tech. I work for a top 10 defense contractor that manufactures satellites and launches them from the Space Coast. Basically, the satellite acts as a repeater. The transmission comes from our earth stations, include voice and data, and transmitted to the satellite which then streams the data (repeats) back towards earth, where a properly pointed dish can receive. The dishes typically are able to send/receive data and the communication to/from the satellite and earth station is two-way, bi-directional.
I have installed commercial dishes for end users (gov't, military, gas and oil rigs, ships). I assure you that they work when pointed correctly at the sky, and don't work if they're just inches off. There's an entire procedure involved in pointing and setting a dish as well as math helps on getting the angles correct. Once linked up, I can send test messages to a Network Ops Center where a tech verifies my data and sends me out a test reply which I also verify.
I also work with microwave (ground to ground stations), fiber, central office, network, PSPC radio, backbone, etc. I'm a tech, not an engineer, so my 25 years of experience involves the installation and maintenance of comm equipment. My work involves correctly pointing, provisioning, and testing large scale wireless communication devices.
FE'rs need to work this info into their model somehow, because satellites exist and are in use all over our flat earth. There's no need to be afraid to admit that they are real.
i have few Question , i will be thankful if you could explain it for me ,
1 ) so you people make satellites , am wondering which material you people use for casing , in thermosphere temperature is 1500 ~ 2000 Celsius , so how it can with stand that much of temperature ?
2 ) In theory there can not be heat transfer in space because its empty nothing there , to transfer heat , so when these satellites are hit by sun rays they will heat up and their temperature should be raising because there is nothing in space where heat could be transfer , so how you people keep it cool ?
3 ) also how you people are lunching satellite in orbit ? i guess rocket will go up and acquire desire speed and then it need to release satellite from its bay in allocated orbit , correct ? so Question is how rocket can acquire speed in space ? because we know newton 3rd law action and reaction , in space there is only one body which is rocket there is no second body to react like on ground we have that air which push planes etc , so how that propulsion is possible in vaccum ? also according to thermodynamics expansion of gases in vaccum result zero work , because nothing to displace ...
4 ) so these satellites all are geostationary or what ? because you said if their is inch difference in alignment it will not work , so you have satellite in orbit which is in motion and ball earth is also in motion , so for dishes alignment the satellite should be in sync 100% with ball earth speed if there is even 0.1% difference in speed , theoretically the alignment should be effected and it suppose to be keep increasing...
sorry for bad english , and too many question , hope i will get answers , thanks
