Approval document issued for IGC Position Recorder
Just a quick opinion (i.e. I'm dodging doing real work):
While I agree with some folks that this isn't a revolution on its own, I view it as a good "first step" towards using pure-GPS units for badges and competitions. There are articles out there already that explain (better than I can) how GPS-derived altitude isn't really "worse" than using a pressure-based altitude-sensor. Given the affordability and reliability of modern GPS units (as well as the lack of a pressure system to calibrate), I think its a good system/standard to move toward. If folks want an altitude sensor for major records, I can concede that. But for simple badges and competitions I don't see the need. --Noel
