Leica CS50 field controller

The CS50 is the next-generation successor to the CS20. It combines the proven field-ready design of the CS20 with major improvements in performance, connectivity, and usability, including a faster processor, 4G and 5G RedCap connectivity, eSIM support, a secure Linux operating system, and a multi-touch display. These enhancements help surveyors work more efficiently with large datasets, CAD files, IFC models, and imagery while maintaining the ruggedness and reliability expected in demanding field conditions. The batteries used for the CS50 are the same as those for the CS20.

The CS50 is designed to support a full working day in the field on a single battery charge. Actual operating time may vary depending on display settings, features in use, connectivity, environmental conditions, and battery health.

The CS50 runs Captivate 2027 and newer versions only. Captivate v12 and earlier versions cannot be installed on the CS50.

In many cases, yes. The CS50 is running Captivate 2027 and newer versions only. However, the CS50 can connect to compatible Leica Geosystems instruments running Captivate v12 or newer, allowing you to continue using your existing equipment while upgrading to the latest field controller.

When connected to instruments running older software versions, some Captivate 2027 features may not be available, as they depend on capabilities provided by both the controller and the instrument.

The Leica CS50 supports connections to a wide range of Leica Geosystems surveying instruments.

Yes. The CS50 is designed to work smoothly with demanding survey data, including IFC models, CAD files, sensor images and large project datasets. Its powerful processor helps keep Captivate responsive, even as projects become larger and more complex.

The CS50 runs on a Leica Geosystems-managed Linux platform designed specifically for professional surveying. This provides fast start-up, stable performance, and predictable software updates, helping surveyors avoid unexpected operating system changes that could interrupt field work.

The CS50 supports two types of connectivity that help keep surveying workflows moving.

Instrument connectivity enables reliable communication with Leica total stations and GNSS receivers through Captivate, including long-range wireless connections to robotic total stations. Achievable operating distances depend on the instrument, connection method, site conditions and wireless interference. For remote operation beyond direct Bluetooth range, the CS50 also supports GeoCloud Fleet's Control, enabling a TS20 to be operated over the internet via the GeoCloud Fleet portal.

Network or data connectivity includes 4G/5G RedCap, WLAN, physical SIM and eSIM support, providing flexible options for connecting across networks, regions and project environments. These features help keep field crews connected to project data, cloud services and office teams throughout the surveying workflow.

The CS50 is purpose-built for professional surveying with IP66 and IP68 providing the highest protection against water and dust, and MIL-STD-810H certification for dual ingress protection and military-grade ruggedness, meaning it can withstand harsh environments and demanding daily field use. An ambient light sensor and tactile backlit keypad can be operated while wearing gloves or in wet conditions, and make it easy to adjust changing light.

The CS50 is designed to work as part of the Captivate ecosystem, making it easy to transfer survey data between field and office. Although transferring data via a micro SD card or USB-C stick is possible, the most efficient way to transfer data to and from the CS50 is GeoCloud. With GeoCloud, you can securely share data, collaborate across teams and keep projects moving efficiently between field and office. With Infinity, you can prepare projects in the office, process measurements and maintain a connected workflow from planning through to final deliverables.

Together, CS50, Captivate, Infinity, GeoCloud, and compatible total stations and GNSS smart antennas, create one connected surveying workflow. Surveyors can prepare projects in the office, measure and perform stakeouts in the field, then transfer data, and process, verify, share, and deliver results efficiently using a field controller designed to stay responsive throughout the working day.
