ublox zed-f9p - need to power cycle?

[Andreas B]

Hi all,

By the end of October I noticed that the number of used satellites dropped down.
This trend of low number of used sats continued until last week (~19.
Nov), when I power cycled my raspi.

After this reboot the number of sats used was back at the
'normal/pre-late-October' (i.e. good) level.
See plots. There is a distinct drop towards the end of october, and
this trend continues until the reboot last week.

What would be the cause of this?
Outdated almanac?
Is it wise to do a power cycle every now and then, or is it necessary?

Best regards,
Andreas
