Two way communication between 2 GPS

Hi,

I was thinking if there is any possible ways to make two GPS modules or shields to communicate to each other? I mean send/receive data via satellite? I tried googling for an hour but could not find any application or such. I'm not sure either if this is doable but I read one article that a base station should have been setup to deliver messages between two or more circuits just like what radio stations do. But is there anyway or chance to make two Ardiunos communicate via GPS without any base station? Thanks in advance.

No. GPS is one-way only.

You could send the data read by the Arduino from it's GPS to another Arduino that has a GPS attached. How you would do that depends on the distance between the Arduinos and the reason for sending the data between the Arduinos. Seems you left those details out.
