The Concept of a satellite being controlled by GPS will not work !

Because GPS is a system of over 30 satellites in orbit providing timing data to a let the hand unit compute position.

It takes a minimum of four overhead satellites to locate your position on earth.

You could not expect that system to work when your device is orbiting at satellite speeds around the earth.

Start small and work your way up. Look into launching your own weather balloon. You can attach a camera to record the journey up and down and attach a GPS tracker so you can retrieve it when it comes back down. You won't get it into orbit but it will get high enough for a good view of space. After that you can start to add a controller and props to help keep it on target. It's an interesting hobby but one that is not cheap.

BTW you may be able to build your own GPS controlled satalite for around $300 but you wouldn't be able to get it into orbit and it may not survive the journey into orbit.

Yes many schools have made satellites. I am not sure what you mean by GPS controlled however.

The delivery system may be your biggest problem but in principle yes anyone with the required skills and cash can build a satellite.

I would however suggest you start small - learn some electronic skills, some programming skills and practice with radio controlled aircraft an drones. When YOU know the answer to your question you will be ready.

Your not paying attention.

  1. your question says nothing about HOW or $300

2. Understand start small and learn skills.

3. Whan you have the skills you will know the answer to your own question.

In the light of you revelations re $300 I change my answer to NO.

HOWEVER

If you can get it into space a mobile phone will probably do much of what we currently understand you need. all you have to do is programme it. (and get it up there)

I got the cart but where is the horse?

Start with everything you need the satellite to do.

Guidance system propulsion system and housing for $300 Good luck.

If you mean a gps guided satellite yes it is possible, whether you can build one is another matter.

How much money and other resources do you have at your disposal?

No.

If you want to make a satellite (I guess, you mean an earth orbiting thingie here), GPS is your smallest problem. You will have to find someone to lift your satellite into the orbit. You will have to build your satellite following their rules (form factor, weight, used materials, shock resistence, thermal resistence ...). You will need a means to communicate with your satellite (radio), one or more base stations for that. The satellite needs a power supply.

What do you mean by GPS controlled? GPS is controlling nothing. At best it gives you your current location. An on board controller can compare the current location with a wanted location and take action to bring the vehicle to the wanted location. For your satellite that would mean a micro controller and some form of thrusters that can control rolling and moving in 3D. GPS will only give you your position in space, you will need a device to get your orientation as well.

And top of all, GPS was designed for on-surface navigation. Commercial devices will assume something is wrong when they calculate a height of some ten kilometers/miles and not output a position fix. You still can use a raw receiver and do all the math yourself. In the end it's just 4-dimensional trigonometry (3D+time).
