GPS Dropouts

We are noticing some dropouts on older systems that only use GPS, as we are getting down to 5 satellites in the late afternoon.

However new systems that are using GPS and GLONASS as well should be OK, see graphs Below.

The Graphs illustrate the advantages our new Topcon Receivers that come with GLONASS unlocked as standard, over older receivers that use GPS Only, or new Receivers that aren't GLONASS enabled.

You should have far fewer problems related to GPS availability if you are using GPS and GLONASS.
