Digital Communication Between Ground Station Using Raspberry PI

Ground Station or Earth Station has a very important role in performing TT&C for satellite, in addition
to that the communication between ground station is also very important for the coordination of operation and data
collection from the satellites.
In the event of a disaster at the location where the earth station is there, will might be disruption of
coordination between earth stations due to lack of Internet as a communication link between ground stations.
To prepare for these possibilities, I conducted research to find other ways of communicating between a ground
stations. Raspberry Pi is a single board computer that is on the rise lately, this device uses minimum energy source,
can even using a battery.
This research involves a several devices, among others transceiver VHF / UHF, antenna VHF / UHF,
open source software fldigi, interfacing and the relationship between such devices to make another scenario for
solve this problem.
This research shows that digital communication between Ground Station can be make via radio frequency without
using connection from internet, ie using a Raspberry Pi and radio to send or receive a digital data from each Ground
Station.
