Re: [Paparazzi-devel] Re: My Hello to the Development list.

[Pardeep Athwal]

Hi Chris,
The modules of switching between GPRS and WiFi I have
developed were not for Paparazzi but were for the
Windows Platform, XP version.  It was an entirely
different project I did at work etc.. It involved
allowing users to have content pushed onto their
computers based on location. 

I have had difficulty understanding the architecture
of your solution, was it airborne i.e. using a radio
controlled platform much like paparazzi?  Or were you
describing a procedure to be able to triangulate
position relative to cell towers?  Fascinating stuff
but I'm not sure how we can implement it in a UAV
environment, especially in a remote area where there
are no cell networks.

cheers,
Pardeep.
