Poor Performance on the LS Lately

[Sage Collins Surv]

We aren't sure if it is just coincidence that we have just been working on job sites that have poor satellite coverage, but for the past few weeks the LS seems to be under-performing and not taking shots as well as it used to, even in decent sky coverage it seems to struggle. Has anyone else been having an issue or have any suggestions on some troubleshooting we could do to jump-start performance? Maybe there is something since the last update that needs to be switched back on or off? Any suggestions would be welcome.

We notice this based on time of day. The satellite coverage seems to diminish from about 2 - 5 est, Dunno about after 5, cause we are normally done for the day @ 5pm.

This happened around this same time last year, afternoons are tough especially in canopy.

I have noticed the same thing. Here in Kentucky it has been extremely wet. Wet leaves are horrible for GPS on top of the poor coverage in the afternoon.

I'm ready for some drier weather. All the rain has made the leaves extra dense and full of chlorophyll.

I have noticed a difference too.

Be careful out there and make sure you have the right solution. This time of day is when I've seen the normal time span to weed out bad fixes be quite larger than normal. I've also noticed some RTPK with a lot of time be incorrect. Alexey likes to have medium duration for processing, so do multiple medium duration shots and compare the RTPK and RTK if you get any that have enough time in them. With some tweeks RTPK will probably be very helpful during these summer afternoon hours.

Sat count is down, in the afternoon. Took 1-1/2 hrs to set 1 (one) corner yesterday afternoon.

Same here. I finally broke out the robot. Afternoon is very frustrating here lately. Another thing I've noticed is the pattern of the shots change. The thumb print I used to see is rare. Now it's like a number 5 on a dice.
