|Using Trimble Corrections Hub||Custom (NTRIP) Corrections|
A Catalyst Decimeter subscription allows you to achieve accurate 10cm GNSS positioning worldwide, using either your own custom-configured* internet-delivered corrections, or using the bundled services available to all Catalyst users through the Trimble Corrections Hub.
Custom local correction require an internet connection and may require a separate account with a local corrections service provider. Trimble Corrections Hub enables 10cm positioning in areas covered by Trimble VRS Now and Trimble RTX-Fast. If you are working outside the VRS Now and RTX-Fast coverage areas supported by the Corrections Hub, the Catalyst Decimeter service can achieve accuracies down to 50cm.
When working offline, Trimble Corrections Hub will automatically switch from internet delivery to using RTX satellite broadcast corrections (via the DA1 antenna).
The latest coverage details for the RTX satellite broadcast service, is viewable here.
