The Leica TS20 is designed to be the ultimate productivity powerhouse for surveyors. It features advanced Al-powered automation, fast and maintenance-free motors, extended reflectorless range, and high precision. With IP66 rating, integrated theft deterrence and Instrument tracking, and seamless compatibility with Leica Captivate software, it's built to handle any surveying challenge reliably and efficiently.

The TS20 minmises mistakes and streamlines workflows with advanced automation. This includes Al-detect, which automatically checks that the prism type entered in the software matches the one you're measuring to, removing prism identification errors. Al-powered ATR ensures measuring is efficient and work continues even in challenging conditions, like misty rain or partially covered prisms. Al-follow, available in 2026, overcomes line of sight interruptions with the AP20 to search and relock for faster and more continuous work in one-person operations. The TS20 can also measure automatically to reflective tapes, saving time and money. Connected to the AP20, eliminate height errors and measure with a tilted pole, easily reaching difficult points to speed up work. With Al-follow, available in 2026, you can overcome line of sight interruptions with the AP20 to search and relock faster for more continuous work in one person operations. Additionally, the small size and weight means it's easy to take the TS20 and it's productivity potential to any site.

Yes, the TS20 is fully compatible with existing Leica field controllers, accessories, and software like Leica Captivate and Leica Infinity. This ensures a seamless transition for existing Leica Geosystems users while providing powerful new capabilities.

The TS20 is built to perform in tough environments with its IP66 certification, making it resistant to dust and water. It also features advanced automation to maintain performance in conditions like misty rain, ensuring consistent accuracy and reliability. Best of all, we continually train the TS20 on new environmental and weather situations, passing along these improvements to you in software updates so you benefit.

The TS20 includes integrated protective features with the GeoCloud Protect, a service offering remote locking, tamper detection, movement alerts so the total station can't be used anymore. With precise tracking capabilities, GeoCloud Protect enables users to locate their TS20 using advanced algorithms, view its location history, and take immediate action via a map-based interface. These features help secure your investment.

The TS20 introduces several significant advancements that make it a leap forward in productivity and reliability. Fast, direct-drive motors follow even the quickest changes in movement and make it excellent for applications like rail, where you need to often measure in 2 faces. Enhanced EDM based on WFD technology provides fast and accurate distances along with an extended reflectorless range. The Al-powered features are another distinguishing factor: Al-enhanced Automatic Target Recognition (ATR), PowerSearch, and Dynamic lock make for fast searches and steady locks. Additionally, with completely new features like Al-detect and Al-follow (coming in 2026), productivity soars with faster work and fewer mistakes. Combined with its IP66 rating, the TS20 will work in the most challenging environments. The TS20 integrates communication devices like long-range Bluetooth, WLAN, or mobile data. Instrument protection and tracking also get a boost with GeoCloud Protect - integrated protection that cannot be removed and allows instrument tracking and locking. And there's more. Check out the data sheet for a full list of the TS20's enhanced specs.

Why is the TS20 the best for everyday surveying?

The standard for productivity

- Measure points faster and with fewer mistakes across conditions

The TS20 is the standard for productivity, delivering excellent performance in the two areas that impact productivity most - how fast you work, and how many mistakes you make.

You need to measure and layout many points per day, while ensuring that data has as few mistakes as possible to really save time and money.

We've taken care of speed with features like Al-powered target search, target recognition, and locking, supported by fast motors and advanced EDM, to make your work faster whether you measure to prisms or tapes. And with IP66-rating, the elements won't stop you either.

To reduce mistakes, Al-detect enables prism type identification, ensuring you record measurements with the right prism type every time. And Al- follow, available in 2026, allows the TS20 to follow the AP20 prism even if line of sight is interrupted.

Altogether, this means more points measured and fewer mistakes. Reducing rework and corrections establishes the TS20 as the ultimate benchmark for efficiency on any project, from cadastral work to construction tasks like railways, tunnel, bridges, buildings, or highways.

The future of robotic surveying

- Excel today and be ready for tomorrow

The TS20 offers the power and efficiency to help you excel today and take on bigger projects tomorrow. Faster motors, long-range EDM, advanced optics, mobile and Ethernet connectivity - the list goes on. It all adds up to the future of robotic where productivity is unprecedented and quality is a given.

Built from the ground up with innovative technology, the TS20 still maintains the familiar user experience you trust. The speedy processor makes Captivate fast to work with, and a multi-touch screen with zooming and panning makes on-board operation intuitive. And with integrated connectivity, you can easily adopt cloud-based data and sensor services now or when you're ready.

Additionally, as the only robotic total station with a neural processing unit (NPU), the TS20's Al automation will continue to evolve with software updates, adapting to challenging environments and weather conditions for reliable target detection and locking.

The TS20's combination of proven quality and accuracy with cutting-edge advancements means your investment returns both immediate success and long-term growth.
