So those the satellites that show up on the monitor are not all being used or do even more satellites show up when you have a 7000/7500?
The United States system is called GPS (Global Positioning System) GPS satellites position the tractor. WAAS (Wide Area Augmentation System) is the correction signal being broadcast for the GPS satellites. The WAAS system improves accuracy by giving corrections to the receiver to account for atmospheric distortions and anything else that might affect the ranging of the GPS satellites.
Newer systems use GNSS (Global Navigation Satellite System) a GNSS receiver can receive signals from US GPS satellites, Russian Glonass satellites, European Galileo satellites and Chinese Beidou satellites.
When I had a GPS/WAAS light bar years ago, it was normally tracking 6-9 satellites. Now I have a GNSS receiver that often tracks 40+ satellites. GNSS is much better along tree lines as it tracks many more satellites.
I don't know the detailed specs of John Deere receivers, but the world has pretty much moved on to GNSS |
WAAS vs SF1 are they the same accuracy?
