I had strange Track Logs by eTrex VISTA. The Data below is all of same time and same place but different among the way of Track Logs. It is obviously deferent internal and external Track Logs Data.
<Fig.1> GPS: eTrex VISTA (Asia) Ver2.18 , DATA: Internal storage
<Fig.2> GPS: eTrex VISTA (Asia) Ver2.18 , DATA: NMEA($GPGGA)
<Fig.3> GPS: eTrex VISTA (US) Ver2.17 , DATA: Internal storage
<Fig.4> GPS: eTrex VISTA (US) Ver2.17 , DATA: Binary Mode
<<get the raw data from links>>
Condition of Logging is a mountain pass, so that I think the condition of accuracy is not good.
Some times the Track Logs had big step down, The "Stepping Data" will be caused when the accuracy change 2D to 3D. Still internal Track Logs did not Stepping.
Any way, I would like to log the same Track Data among internal and external.
Why the Track Log Data is not same among internal and external? I want hear from GARMIN.
