Eliminate track segments between GPS off and on points

From home I drive to the airport, GPS is on, correct track is recorded.
From departure airport to destination airport GPS is off, nothing is recorded.
At destination airport, car rental, GPS is turned on again, and correct track is recorded as driving away from the airport.

When displaying on the GPS and/or downloading the GPS data to BaseCamp, the above trip would have a straight - never traveled - line drawn between the two airports. That line is not based on a GPS measurement and is unreasonably too long to have value as a straight line, therefore it should not be part of a track. It should be easily deleted, suppressed or marked with different color/pattern.

Any way to filter out these never happened track segments from BaseCamp?

(I understand that some level of extrapolation and direct connecting is needed between the sampled datapoints to create a track. But that should be subject of speed and absolute/relative distance, maybe to satellite reception and/or GPS on/off status and should not be a straight line between London LHR and Tokyo NRT.)

    Split the track into multiple tracks. Each track can then have its own colour.

    Delete the segments that upset you.

    If the tracks are all in the same list then they are all visible at the same time. They can all be selected at the same time so that cumulative data can be shown.

    It works for me.

    You don't say what GPS you're using but for a handheld this is perfectly normal. If you don't want the straight sections recorded do a Save current track at the end of one leg and then a Clear current track, having got a satellite lock, before you start the next.

    Original device: Vista eTrex HCx and its earlier versions (now managed in BaseCamp)

    Split the track into multiple tracks.


    How is it done in BaseCamp?

    Save current track at the end of one leg and then a Clear current track, having got a satellite lock, before you start the next


    The problem is the design of the GPS or my inability to figure out how to use it. I only can save 20 tracks even though I have an external memory card inserted. 20 tracks to save are way too few, I would run out of space (track numbers) very quickly by saving/starting a new track every time during a 2 month-long trip. Any workaround? Or any way to save the tracks instead to the memory card? My settings are:

    Vista eTrex HCx
    Tracks
    Track Log ON
    Saved Tracks: [has 2 tracks: 12-JAN-16, 12-JAN-16 02]
    Setup
    [DISABLED] Wrap When Full
    Data Card Setup
    [ENABLED] Log Track to Data Card
    Yet here, in the Data Card Tracks field, I do not see, for example, the most recent saved tracks that are displayed in the max-20-only list under Tracks>Saved Tracks (12-JAN-16, 12-JAN-16 02).
