how can i transmit some signals into space? (home-project)?

Every time you talk on your cellphone you are transmitting signals into space. It isn't like you need anyone to be able to receive your transmissions. That said, how big do you want your home project to be? You could build a big transmitter with old radio parts from some crazy old man who is still in love with his childhood as a ham radio operator.

probably there are service providers in your area that can offer you WiFi connections across those 10kms with no complexity.\nIf you are trying to do it by yourself, you will need microwave antenas aligned in a careful way at every point which you want to provide conectivity and repeaters, so wireless users can detect those signals

go to radioshack.  they sell all kinds of converters etc.

To boost the signal of your wireless router I would recommend buying a suitable enhanced antenna from your local computer store. They are designed to work with your router. There are also signal boosting devices that can be used throughout your home/office to help increase your signal coverage and wipe out dead spots.\n\nAs for the Sat dish; if you want to be Dr. Frankenstein and experiment you can go to your local Radio Shack and get the proper adapters to convert the connection from one to the other. Not sure if they will have the proper adapter for the router though. You may have to improvise. Will you succeed? I am very doubtful. Sat dishes are used to RECEIVE SIGNALS, not TRANSMIT! You may get better luck just using the coax cable used with the dish. But then again, stranger things have happened...

Despite the Rolling Stones song, you can't always get what you need. And everyone knows you don't always get what you want.\n\nSatellites broadcast to a fairly large footprint on the ground. So you can, if you're in its footprint, and with an appropriate antenna, properly aimed, and an appropriate low noise amplifier, receive a signal. Whether you can make sense of what you've received is quite something else altogether. TV satellite broadcasting is protected from indiscriminate reception with one or more technological tricks. You can, unless the box vendor is the FBI in desguise, buy 'descramblers' for satellite and cable TV signals in the backs of various magazines. On the Internet side, you presumably want to receive the contents of this or that web site, not just any old broadcast of Internet data, and so even if you can descramble (for free because you've got your own descrambling box now) a satellite signal, it won't be what you wanted. \n\nSo, you must have the ability to send control signals to the broadcast origin point (always a ground station somewhere, given the constraints on space and weight for these satellites). \n\nAnd they'll ignore you without an account (and so $ from you) for two reasons. You don't have an account on their computers which allows you to arrange for connections to the Internet (and the Web site you're after), and you don't have the appropriate authenticaiton to talk to the satellite so it will pass your control signals back to the ground station. \n\nSince satellites are expensive to design, build, launch, and maintain, there are no hobbyist groups providing free Internet access. without that, you're limited to commercial services (or government service if you're eligible) and they will universally require some sort of authentication (typically cryptographic at the information carrying level, and usually some raw signal based authentication as well) before you can use the system, and that will require a business relationship before they will set one up for you. And for that they will want a fee.\n\nI think you aren't going to get what you want. And you're probably not going to get what you need, if you define it as free Internet access by satellite. I recommend WiFi or something similar, if it's possible where you're located.

My guess is that they would still work-you would not get an accurate reading of your position though-what coordinate system or projection is space in? and the reading would have to bounce back into earth from a reading station and then back to the GPS units-\nWhich brings up another question? Would signals be lost in translation?\nI really don't know\nBut its gonna bother me.

Your question is too vague to properly answer.  However, I can suggest looking at mosix for a distributed system.  Types of sensors and what is the ultimate goal of the project will help me to better answer you.

Check Radio Shack, they have all that stuff.

Go here and register ( Free )..Plug in your location.\nThe site tracks several satellites and the space station.\n\nhttp://www.heavens-above.com

Your transmitter will work, your receiver won't.\nbut you could bounce the signal onto a simple solar cell\nconnected to a set of headphones and you should be\nable to receive a weak signal...\nYour receiver won't work because light won't move the paper and the grains of sand.....

Best Buy sells them. They are like a miniature satellite dish that beams the signal. I have never tried one but I hear they work well.

I don't understand why you want to start with a FM signal, and then need to revert back to a FM signal....?\nIf you already intend to use a fibre optic cable, then why not just send your digital signals from surface to ROV?  \nThese guys may have some handy stuff to achieve this:  http://www.esssales.com/ifo/fiberoptic-kits.html\nI can't think of an easy method of converting PWM signals into a FM radio signal.....

Are you refering to communication to submarines.\n\nCheck out the ELF project, extremely low frequency telecommunications.
