I've noticed that around 2pm Central time that RTK gets very challenging in canopy. I've not used mission planning in years, but I finally took a look today. GPS from 9am to 6pm in my area is between 7 and 8 sv's above a 10° mask, and drops to 6 briefly at 2pm. At 10pm there are 12 GPS satellites available above 10° and then again about 5am there are 10+.
Interestingly, Glonass also drops considerably along with GPS.
This is a very handy and easy to use mission planning site if you don't already have one available:
