Subject: RE: [Aus-soaring] FLARM altitude source To get around the altitude inaccuracy problem, has anybody tried looking at a combination of GPS and baro-altitude, similar to what is done with embedded GPS/INS technology. The GPS could update the altitude on a long-term basis and the baro-altitude could "fill in the gaps" by integrating the rate of climb or descent which should be more accurate than GPS altitude on a short term basis. I'm not a technical guy so I don't know if that's possible within FLARM but it alleviates the weakness of both altitude sources and the technique is currently used in fighter aircraft to accurately determine altitude for the bombing computations. Over to the technical people to work out if it's feasible...
