I’ve mentioned before the GAISS project (here and here). It wasn’t in the original plan, but we are now receiving the MAP27 information from the ‘base’ radio, and making them available for a small conversion appplication that re-transmits them on the National APRS frequency of 144.800Mhz. This allows us to leverage the already existing APRS infrastructure in place to get our ‘position packets’ to go around corners where there is no existing RF path.

Our GAISS GUI will then be able to pluck the relevant data from the APRS data stream and plot the positions of the SEMRA personnel that are out walking for the event. Delighted as we are to have this much working (and that we will have something to show at the Galtee Walking Festival), we are still a long way of a ‘finished’ prototype.
