Trimble ST30

• The most accurate optical and tilt GNSS on the market
• Always-on GNSS-assisted GeoLock – fast target lock that tracks beyond line-of-sight – no subscription needed
• Top-mounted accessory slot – measure the way you want to
• Engineered for longevity: Features a Titanium tip that is 6x harder than standard alloy tips
• Designed for the real world – robust design can survive a 1.5-meter drop onto concrete
• Seamless ecosystem integration – the ST30 works instantly with the Trimble software you already use, including Access, FieldLink, and Siteworks

For Land Surveyors

Effortlessly perform topographic surveys, stakeouts, and as-built verifications across diverse environments, from open fields to dense tree canopies. With the ST30 you don’t need to lose time switching between total stations and GNSS workflows depending on line-of-sight. Never lose your prism lock in obstructed areas and say goodbye to manual levelling on uneven ground.

• Operational Flexibility – the ability to switch between optical and GNSS modes within the same job file with zero downtime.
• Workflow Continuity – Active Tracking and GeoLock allow your total station to re-acquire the target in seconds after an obstruction, keeping the crew moving.
• TIP™ Tilt Compensation – measure building corners or inverts without offsets or manual levelling. It just works.

For Site Engineers

Confidently complete high-pressure layout tasks and multi-trade coordination in chaotic, confined construction sites. With the Trimble ST30 you never need to update the rod height in the controller, eliminating a common cause of catastrophic rework, such as incorrectly poured concrete. You also never need to worry about the frequent line-of-sight interruptions from machinery, vehicles, or sub-contractors.

• Auto-Rod Height –  eliminate “rod height busts” by automatically syncing height changes to the field software, preventing costly rework
• Efficiency in Chaos  – tilt compensation allows you to measure around piles of rebar or machinery without moving the total station setup.
• Target ID – make sure you only lock onto your specific prism on busy sites with multiple reflective targets.

For Infrastructure Project Leads

Ensure your technology supports your management of large-scale road or rail projects where safety, vertical tolerances, and speed of execution are critical. When 5-12% of your project budget is wasted on unplanned rework, accuracy and speed of measurement matter. The ST30 ensured strict vertical tolerances for material yields (like pavement thickness) and prioritise keeping boots off roadways and railways for safety.

• Safety & Reach – tilt compensation allows for measurements in dangerous or inaccessible areas (like the edge of a busy roadway) without needing to stand directly on the point.
• Precision Control – numerical QA/QC accuracy on the screen means you can trust vertical tolerances for expensive materials in real-time
• Massive Productivity Gains – up to a 20% improvement in measurement and layout speed, which is vital for meeting tight possession windows

The Trimble ST30 requires:

• Trimble Access 2026.20 or higher
• TSC5/510/7/710 with Empower 140 module
• Autopole telescoping rod
• An S7 or S9-series Total Station with upgraded radio module (Trimble BLR) – compatible total stations with DR+ made after c.2019 can be upgraded
