The new Leica TS30 total station is unique. This new total station has redefined precise surveying by offering unmatched accuracy and quality. Never again will surveyors with demanding tasks need to make compromises, the TS30 total station is ready for any challenge. When only 0.5" accuracy is acceptable.

Pride in accuracy
Surveyors take great pride in accuracy. The Leica TS30 delivers impressive performance in individual disciplines. But most importantly it is a champion in perfectly combining angle measurement, distance measurement, automatic target recognition and motorisation. The accuracy of the Leica TS30 is in a league of its own, a true companion for surveyors with pride.

Automated One-Person Surveying and GNSS Extension

Setting new benchmarks in trust
It all started more than 75 years ago with the Wild T3 precision theodolite that stunned the surveying community with highly accurate measurements. Now, four generations later, Leica Geosystems continues to build on the values of accuracy and quality. The latest generation of Champions, the Leica TS30 total station has reached the pinnacle. Generations of surveyors have trusted in accuracy and quality from Leica Geosystems, now it's time to take this trust to the next level.

Angle Measurement
The angle measurement system - for horizontal and vertical angles - is a very significant component of the Leica TS30. It must guarantee highly precise and accurate angle measurements under the high speed performance of the direct drives.

important characteristics and advantages of the Leica TS30 angle measurement are the high measurement frequency - up to 5000 angle measurements per second - and the quadruple angle detection system.

The angle measurement accuracy of the Leica TS30 is proven and certified by Leica Geosystems' TPM-2. This Theodolite Test Machine is part of Leica Geosystems' calibration laboratory for length and angle. The laboratory is accredited by the Swiss Accreditation Service SAS, which belongs to the Swiss Federal Department of Economic Affairs DEA. The standard deviation (1s) of the TPM-2 angle measurements are 0.018mgon (0.058") for horizontal angles and 0.028mgon (0.091") for vertical angles. To test the angle measurement accuracy of the Leica TS30, the horizontal and vertical angle measurements are compared with the measurements of the TPM-2.

The standard deviation is calculated according to ISO 17123-3. For the Leica TS30, the angle measurement accuracy is 0.15mgon (0.5").

Motorization
The motorization of the Leica TS30 uses direct drives based on the piezo principle, which directly transforms electric power into mechanical movements.

The Leica TS30 is the only total station which uses direct drives based on the piezo principle for horizontal and vertical movements of its alidade and telescope.

The direct drives using piezo technology enable high speed motorization and acceleration capabilities together with infinitesimal step sizes at low power consumption. The step sizes reach the range of nanometers. Unmatched durability and extended maintenance cycles of the direct drives are achieved by a subsequent elimination of the transmission drives moving parts. No gears are used for the movements. Furthermore, the Leica TS30 direct drives do not produce a magnetic field nor are they affected by them. This guarantees the unrestricted operation of these direct drives in magnetic fields as they can appear for instance in electric power plants.

Compared to conventional drives, the main advantages of the Leica TS30 direct drives are the following properties:

High speed (up to 200gon/s)
High acceleration (up to 400gon/s2)
Long durability and robustness
No noise emission
Compact design
No power consumption at rest

Electro-optical Distance Measurement
For the electro-optical distance measurements (EDM) on prisms, reflector tapes or natural targets, a visible laser beam, which is coaxial to the optical axis, is transmitted by Leica Geosystems' PinPoint EDMsystem.

Leica Geosystems' reflectorless PinPoint R1000 EDM measures to natural targets at ranges of more than 1000m. To realize these long distance measurements without any prisms or reflector tapes, Leica Geosystems' proven System Analyzer was implemented. This procedure allows the evaluation of the total signal information for the distance determination and combines the advantages of the phase and time-of-flight measurements without having their individual disadvantages.

For the Leica TS30 total station, the Leica PinPoint EDM was improved to achieve even greater accuracy. The established PinPoint EDM enables distance measurement accuracy, on Leica round prisms (GPH1P), of 0.6mm + 1ppm (tested according to ISO 17123-4).

The PinPoint EDM provides many advantages for the distance measurements of the Leica TS30 total station. Beside the very high measurement quality and reliability, the Leica PinPoint EDM allows measurements even under adverse atmospheric conditions, such as dust, smoke, mist, rain or snowfall, etc.

Beside electronic and signal analyzing improvements of the distance measurements, the shape of the laser beam was significantly improved. This results in an optimized laser beam profile and footprint.

Cross-sectional Drawing
This picture shows a cross-sectional drawing of the Leica TS30. The drawing visualizes, in particular, the position and size of the horizontal and vertical coded glass circles.

The coded glass circles are part of the horizontal and vertical angle measurement systems. An important influence to angle measurement precision and resolution are the size of these circles. A larger diameter improves the angular precision and resolution. Therefore, the diameter of the Leica TS30 coded glass circles have been enlarged approximately 15% compared to typical 1"-total stations. The design and construction of the standards and the alidade considers the size of the enlarged coded glass circles.
