Hi.

I want to fly for longer ranges (less than 20 km).
To do this, I need RX, TX, OSD and GPS and some other things and there is no problem to get them.

But I have many problems here.

My flights were all in lower ranges (maximum distance of plane from radio control: 1 km).
For fly for longer distances, I think I know how to use some devices but I know nothing about Ground Control Stations.

For a long range flight, I need to connect OSD to video camera, servos, Video Tx, Radio Rx and GPS.
These are for inside of UAV.
What I need for outside of drone (for GCS)?
How can I receive data (online videos from UAV camera) and how can I see it?
Or the other problem, how can I see the videos on laptop?
Please help me to get my answers, I know nothing about connections of GCS and I don't know any GCS software.

Helloooooooooooooooooooo ...
No one here can help me to get answers of my questions!?

In general, I think you will find most of your questions answered at the FPV forum: http://www.rcgroups.com/video-piloting-fpv-rpv-469/

If you want to include an autopilot in your setup, two examples can be found here:

Thank you, anyway.
About FPV, I think I got many of my answers (except one thing).

might be worth looking at diydrones.com, the autopilot listed above. the have a mission planner that uses a 900 mhz frequency to transmit the data back and forth.

In regards to the laptop, there are devices that convert composite in and plug into your usb port kinda like a webcam. Assuming your fpv camera outputs in composite. I've found using these devices increases latency noticeably however.
