Re: Altitude data from TT AIO

GPS receivers use a system known as SWAG (Scientific Wild-A$Z Guess) to determine altitude. The fewer satellites it can ¡°see¡±, the more ¡°guess¡± and less ¡°science¡±. Garmin has a good description of it here: ? ? To get a more stable (but still not accurate) reading, make sure it has as much of a 360 degree field of view as possible. ? 73, Jack KE4LWT ?

In prep for a foot race, I got the TT AIO out, and verified operation at my house.
I checked the altitude data it was sending out and it was all over the place, considering that the?
TT was sitting motionless in my window (inside my house, exposed to the south, vinyl siding).
There was no pattern to the random altitudes being transmitted.? The position was steady, the altitudes varied about 200 feet if I recall correctly.
Anyone else experience this?? If so is the SOP or is there something that can be done to resolve the unstable altitude?
thanks
