SkyView's NMEA output is pretty standard. In fact, anything that can take data from a Garmin portable should have no problem receiving data from SkyView. We haven't tested with any ELTs here, though, so no promises that brand X will work. That said, if we find that there's some incompatibility that we can fix on our end that doesn't cause us to have to output non-NMEA-spec data, we generally will do what we can.
