How it works


Choose Your Precision

From centimetres to sub-meter, simply pick the Catalyst subscription level to suit your needs.


Purchase Your Subscription

Pay per hour, per month, or per year. Catalyst subscriptions deliver GNSS performance and corrections as an all-in-one service.


Grab a DA2 Receiver

Lightweight, inexpensive and precise, the DA2 for Catalyst works with every Catalyst subscription level.


Connect & Go!

Connect your DA2 to your phone or tablet, launch your app, sign-in to Catalyst, and away you go!



Catalyst subscriptions are available at a range of accuracy levels to suit your particular job requirements.

Catalyst 1 = Centimeter-level (1 cm)

Catalyst 10 = Decimeter (10 cm)

Catalyst 30 = Sub-foot (30 cm)

Catalyst 60 = Sub-meter (60 cm)

Whether you’re carrying out mapping or mobile GIS data collection projects, Catalyst has the positioning accuracy for every workflow.



You’re always in complete control over how much you spend and when you spend it. What could be simpler?

Catalyst monthly and annual subscriptions are ideal for seasonal, project-based, and predictable usage.

Purchase a subscription for one month-at-a-time, multiple months-at-a-time or annually for a fixed number of users, at the level of accuracy you and your teams require

Catalyst On-Demand hourly usage plans are perfect for unpredictable and fluctuating usage and team sizes. Purchase from as little as 10 hours at a time for use by any number of users, and receive centimetre-level accuracy for your workflows.



Catalyst subscriptions include worldwide and configuration-free access to Trimble correction services through the Trimble Corrections Hub (TCH) which bundles access to Trimble VRS Now and Trimble RTX services for every subscriber at no extra cost.

TCH dynamically selects the appropriate correction service based on the environment, availability, and your subscription level.

Or, use your own local correction sources if you prefer.

Field App options

Apps are the key to the innovation of Catalyst. Any location-enabled workflow can take high precision GNSS and add value or drive efficiency through the benefits of affordable, accessible precision.

Choose from Trimble’s own Catalyst-ready apps, such as Trimble TerraFlex and Trimble Penmap for Android. Or, bring your own app and see how Catalyst transforms the way you work.
