NOTICE
The settings contained in the text below have been thoroughly tested and verified. The change in settings resulted in improved RTK availability in real field conditions when used with the Slingshot® system. However, Raven Industries in no way guarantees or warranties the equipment configuration of non-Raven equipment. Please contact your Trimble customer support for further details.
To ensure optimal RTK signal availability with the AgGPS 262/AG-372 receiver, it may be necessary to adjust the DOP mask settings. While a low RTK DOP mask setting provides high confidence in GPS position, GPS constellation settings often drop RTK fix in some geographic regions.
Trimble provides a DOP predictor tool that assists in determining acceptable settings for specific geographical areas. Adjust the receiver settings as indicated below to change the "to fix" and "when fixed" conditions.
If the settings do not match what is shown, toggle through the options until the settings change to match the settings shown. To change the settings.
