Trimble Catalyst
Trimble® Catalyst™ is a revolutionary GNSS positioning service, delivering high-quality positioning for the light-weight Trimble DA2 GNSS receiver. The Catalyst solution works with Android mobile devices, transforming the device into a powerful, centimeter-accurate mapping, navigation and measurement tool.
Trimble DA2 GNSS receiver and Catalyst works seamlessly with MALÅ Controller App and Easy Locator Core. The solution delivers precise, on-demand, GNSS positioning for your GPR surveys.
What is Trimble Catalyst?
Trimble Catalyst is an on-demand, subscription-based GNSS positioning service that brings survey-grade accuracy to mobile devices, paired with a lightweight GNSS receiver, enabling flexible high-precision location workflows.
The solution consists of a few key pieces:
- compatible GNSS receiver (e.g. Trimble DA2)
- Catalyst software installed on Android mobile device
- a subscription plan giving access to a real-time GNSS correction service (Trimble Correction Hub)
Why Trimble Catalyst?
Lower upfront hardware cost: Instead of buying a full survey-grade GNSS system with large investment, you pay for a lightweight receiver + subscription.
Scalable & flexible: Choose the accuracy you need, when you need it. You can scale up/down depending on project.
Works on your mobile device: Leverages Android devices and location-enabled apps you may already be using.
Good mobility: Lightweight hardware, less setup time compared to traditional GNSS/total-station workflows.
How does it work?
Breakdown of the workflow and technology:
Through an agreement with Trimble, Guideline Geo can offer Easy Locator Core customers in Europe cm-level of accuracy.
Mount or attach the GNSS receiver (DA2) and connect it to your mobile device (Bluetooth).
Install the Trimble Mobile Manager app on your mobile device and log in to your account where the active subscription resides.
Launch a compatible field app (MALÅ Controller App) on your mobile device. The mobile device will now receive high-precision coordinates from the Trimble turn-key solution.
Application areas
Trimble Catalyst is especially useful in workflows where high-precision positioning is required but you want flexibility, lower upfront cost, and mobile deployment. Use-cases includes:
Construction layout: for example using Catalyst + FieldLink to stake out structures, underground utilities, etc.
GIS mapping and asset data collection: for utilities, environment, infrastructure.
Surveying and land administration: where centimetre or decimetre precision is needed.
UAV ground control: setting precise ground control points for aerial/drone mapping workflows.
Features and Benefits
Works seamlessly with MALÅ Controller App
Catalyst supports any location-enabled app on your mobile device. That means you are not locked into only proprietary apps — Catalyst works seamlessly with MALÅ Controller App, ArcGIS Field Maps or others, provided they can accept the high-precision coordinates.
Licensing/term options
With purchase of Easy Locator Core and Trimble Catalyst, (for European customers only) 10 hours of active usage is included.
Accuracy levels
In cooperation with Trimble, Guideline Geo offers survey-grade centimeter accuracy for European customers.
Low upfront hardware cost
Instead of buying a full high-end GNSS system, you only need the DA2 receiver + mobile device + subscription.
Global corrections via Trimble Corrections Hub (TCH)
The subscription includes access (automatically) to the Trimble Corrections Hub, which delivers correction services (such as VRS/RTX) around the world, without the user having to manually configure complex correction links.
Simple setup & mobile workflow
Wirelessly connect the DA2, launch your app, sign in, and go. Less infrastructure, less hassle.
Trimble DA2 receiver
Multi-constellation, multi-frequency GNSS support: GPS, GLONASS, Galileo, BeiDou, QZSS, NavIC, SBAS etc.
Multi-frequency (L1/L2/L5/MSS) support → better accuracy, better performance in challenging environments.
Lightweight & rugged: Dimensions approx 128×55 mm, weight ~330 g. Rugged design (IP65 rated, MIL-STD-810G for shock/vibration).
Connectivity: Bluetooth, USB power input. Compatible with Android and iOS devices.
Flexible mounting: Can be pole-mounted, backpack, handheld via accessory handle etc.
Performance scales: For example, for RTX corrections (via TCH) the DA2 spec says horizontal accuracy ~2 cm RMS under good conditions.
