Wireless solution for 5,10 and 20 kilometer range

I need to put a system in a rocket which has a communication like with base station. The distance for the rocket in upwards direction is 5km for 1 rocket, 10 km in other rocket and in the last bigger rocket, its 20km.

Any idea about a possible wireless chips to be used? I have a 256kbps datalink requirement. Our project website is www.projectstratos.nl

Please reply. Thanks in advance.
