The Trimble Catalyst DA2 is a software-defined GNSS antenna that brings flexible, scalable positioning to contractors and field professionals using Android and iOS mobile devices. Unlike traditional hardware-locked receivers, the Catalyst DA2 adjusts its performance characteristics through software, allowing you to select the accuracy tier that matches your project budget and requirements.
This innovative approach to mobile positioning enables contractors to start with sub-meter accuracy for rough layout and site reconnaissance, then upgrade to centimeter-level accuracy for precision stakeout and verification—all from the same hardware. The Catalyst DA2 tracks all major GNSS constellations (GPS, GLONASS, Galileo, BeiDou) simultaneously, ensuring reliable positioning in urban canyons, forested areas, and other challenging environments where single-system receivers underperform.
Field workflows become more efficient with Catalyst DA2 integration into Trimble mobile applications or third-party Android/iOS apps. Surveyors conducting boundary surveys benefit from subscription-based accuracy tiers that can be adjusted month-to-month based on project demands. Construction crews performing rough grading or equipment positioning appreciate the flexibility of choosing sub-meter accuracy when centimeter precision isn't required, reducing subscription costs while maintaining the hardware investment.
The antenna's compact form factor and mobile-device integration make it ideal for professionals who need positioning data without investing in dedicated survey-grade hardware. Setup is simple—attach the antenna to your device, activate your chosen accuracy subscription, and launch your positioning app. Express Tools helps contractors and surveyors evaluate Catalyst DA2 subscription tiers and identify the accuracy-cost balance that optimizes project economics. As your authorized Trimble dealer, we provide device compatibility guidance, subscription activation support, and training on integrating Catalyst DA2 data into your field workflows. Our team understands the diverse positioning needs of construction and survey professionals and helps you select the right accuracy tier for each project phase.
