What Happens When your Correction Source Drops?
The ability of your GNSS receiver to get and maintain RTK Fix can be affected by
Spotty or limited internet connectivity
Obstructions that block satellite visibility, such as buildings, trees, or fences
Working outside of the service coverage area
Increased ionospheric activity (such as during solar storms)
Base station maintenance or local service outage
Selecting the wrong mount point
If your GNSS receiver cannot achieve RTK Fix, it automatically applies the best available correction source for your environment. The table below lists the correction sources in the order that the receiver attempts to use them.
Correction Source | Accuracy | Subscription Required? |
|---|---|---|
RTK Fix | 2 cm typical | Yes |
RTK Float | 10 cm | Yes |
Altas* | 10 cm | Yes |
GALHAS* | 20 cm typical | No |
SBAS | Sub-meter typical, | No |
Autonomous | 2-5 meters | No |
*Atlas and GALHAS (Galileo High Accuracy Service) are only supported on the Geode GNSS receiver. An Atlas subscription can be used on the GSN3 (single frequency) and the GNS3H (multi-frequency) models. To use GALHAS, you must be using the Geode GNS3H.
Juniper RTK is a Network RTK correction service offered by Juniper Systems that enhances GNSS accuracy and works well with all Juniper Systems GNSS receivers. You can purchase Juniper RTK through a certified Juniper partner, online through the Juniper RTK web page, or as an add-on to your Uinta subscription.
