[gpsd-users] issues with u-blox m8l ADR

[Jorick Astrego]

Hi,

Currently I am working on a project and happily using gpsd. Thanks for all the effort!

After hooking up an u-blox M8L ADR gps we are having some issues.

The M8L supports the "UBX-NAV-HNR (0x01 0x37) High Rate Output of PVT Solution", but gpsd only outputs at the normal rate. I could add it to the code base but don't have a good feel on where all the places are I need to make changes. I added the message to driver_ubx.h but it feels a bit to easy ;-)

The second problem we have is that gpsd has the fix as 2D. This way I cannot get the altitude that we need. 2D should be fine and there is an elevation output in the tracklog .... but not in the gpsd output.
Any idea how I can get the elevation with the c++ client?

gpsd tracklog:

<trkpt lat="52.207095" lon="6.892893">
    <ele>37.327122</ele>
    <time>2016-04-21T12:23:51.600Z</time>
    <fix>2d</fix>
   </trkpt>

gpsd client output:

{"class":"TPV","device":"/dev/ttyACM0","mode":2,"time":"2016-04-21T12:41:51.200Z","ept":0.005,"lat":52.207113476,"lon":6.892965312,"epx":2.251,"epy":3.180,"track":202.0090,"speed":0.801,"eps":0.10}

Met vriendelijke groet, With kind regards,
