Frequency of measurement

[kiwikid (Jeffrey)]

Hi there,

I am using firmware 0.4.9 and 1.2 image. I noticed that after doing the post-processing to generate the .pos file (rnx2rtkp), the time stamps do not necessarily occur at regular intervals. I am sampling at 5Hz and as far as i can tell, the .obs files are all at 0.2s increments as expected, but the .pos file has large gaps in the time measurements - I am not sure if this is because the rover is not moving and this is a way to save memory, or if it is something else? Does anyone know?

I believe this is the most obvious answer:

Reach XYZ output freeze!

Perhaps the times when there is no XYZ output are times when there is no solution status? No solution = no output. see the comments here: If this indeed is what is happening, then you may need to create some code to repeat the last known coordinate, or maybe predict and project your traveled path. It would not be good for Reach to blindly output a coordinate when there is no current coordinate solution, but you can do that if it fits your use case.
