Loosing time Marks

I have a new problem I never had in the last year, i don’t remember if it began after upgrading firmware, I have v2.11.0.
In the last 6 surveys (700/1200 pictures) the number of the pictures is not the same as in the log, sometimes is ok, sometimes the log is missing, I see it creates more Rinex logs than number of flights/times I turn on the plane.
what should I check?
Thank you

Hi @lanzo,

Thanks for the report! We’ll look into the issue.

Could you please currently use logging of raw data in UBX format? There are no problems with time marks for UBX logs.

Dear Tatiana, I have downloaded and converted the UBX log and I get the same number of pictures


It seems that is missing the take off, I can only see the landing in this graphic
but even without strenght signal it must save timemarks as I test it inside the house and it works

first picture camera time / reach time: 11:06 / 14:07:35.285
latest picture camera time / reach time: 12:17 / 15:18:54.210

Last picture seems ok


First picture seems not ok

I have checked the APM LOG and it shows the correct number of pictures ( I use 2 cables from the camera, one goes to pixhawk and other goes to Reach)

This is the flight log from MP, you can see it shows the takeoff while the reach not, (I have waited for the reach to blink green before takeoff ) MissionPlanner_2018-09-04_10-30-17

Curious about this issue as well-

It was documented in 2017 that certain settings caused missing events (see here)

Has this been resolved with Reachview updates, or is that chart still the only reliable settings?

I use GPS and SBAS @ 10hz, working well for a lot of time, but the problem here is the first part of the flight is missing, not just the time marks.
Today I have updated to 2.14.0-r0, build new adapter and double checked everything, tomorrow I will try again, I have a lot of succesful surveys with this plane, I think the only thing I have changed is the reach firmware.

Hi @lanzo,

Please try with standard configurations for time marks logging in our docs.

Let us know about the flight result.

Are there plans to provide more standard configurations in the future, or is this hardware limited?

Hi @b_airben,

These configurations were provided depending on the transmitted data size and the update frequency. If you specify Reach in another way, there is a big chance you’ll lose some time marks.

Thanks, I take that to read ‘hardware limited’.

In other words, at no time in the future will I be able to use GPS+GLONASS+GALILEO at 5 Hz (for example) with time marks, regardless of Reachview improvements?

In the meantime, it’s hardware limited.
