A-geo ALPHA Y Android Total Station with SurPro

Android total station for construction and engineering surveys

The ALPHA Y Android Total Station brings optical surveying and modern field software together in one instrument. It is designed for surveyors, construction professionals, civil engineers and site teams carrying out setting-out, topographic surveys, control measurements, as-built checks and infrastructure work.

Unlike a basic total station that depends heavily on external software or a separate controller, the ALPHA Y runs Android 11 and supports SurPro 6.0 directly onboard. This gives field users access to project management, station setup, data collection, stakeout and calculation tools from the instrument’s touchscreen.

Precise angle and distance measurement

With 2″ angular accuracy, the ALPHA Y is suitable for routine construction control, building layout, road projects and general engineering surveys. Its absolute encoder angle-measurement system provides dependable horizontal and vertical observations for positioning and alignment work.

Distance measurements have a stated accuracy of 2 mm + 2 ppm when working reflectorless, with reflective targets or with a prism. In practical fieldwork, this supports accurate coordinate measurement, dimensional checks and stakeout across small and medium-sized construction sites as well as longer survey baselines.

Measure up to 1,000 m without a prism

The reflectorless electronic distance meter can measure suitable surfaces at distances of up to 1,000 m under good conditions. This is useful when a survey point is difficult, unsafe or time-consuming to reach with a prism.

Typical reflectorless applications include building façades, roof edges, bridge elements, tunnel surfaces, stockpiles, excavations and features located behind barriers. The operator can capture these points directly, reducing the need to place personnel in hazardous or restricted areas.

Long-range prism measurement

For control work and longer observations, the ALPHA Y offers a stated range of up to 5,000 m with a single prism. Reflective-sheet measurement is available up to 1,200 m under suitable conditions.

Prism measurement remains useful where stable target definition and repeatable observations are required. It can be used for site control, alignment checks, structural positioning, road construction and other tasks where the surveyor can place a prism at the required point.

SurPro 6.0 onboard surveying software

SurPro 6.0 turns the ALPHA Y into a complete field surveying workstation. Users can create and manage projects, organise point databases, import design information and export measured results without transferring every task to office software first.

Station setup functions include known-point orientation, multipoint backsight, azimuth setup, free-station setup, orientation to a line and height transfer. These options help field teams establish the instrument in different site conditions, including locations where it is not practical to set up directly over a known control point.

Point and CAD stakeout

The software supports point, line, spiral, CAD and road stakeout. CAD drawings can be used as a graphical background, helping the operator identify design points and lines visually rather than relying only on long coordinate lists.

This is especially practical for foundations, grid lines, utilities, kerbs, structural elements and landscape features. The operator can select the required design position, follow the displayed stakeout guidance and record the completed work within the same project.

Road and infrastructure workflows

Road-design and stakeout functions support alignment-based engineering projects. Survey teams can work with centre lines, vertical profiles, chainages, cross-sections, slopes and related design elements when setting out or checking road construction.

Additional functions for remote height, offset measurement, multi-round observations, electric-line surveys and tower stakeout expand the instrument’s use across utilities, transport, energy and civil-engineering projects.

Field calculations without returning to the office

SurPro 6.0 includes practical coordinate and geometry tools for calculations that regularly arise on site. These include area and volume calculations, coordinate forward and inverse calculations, intersections, resections, offsets, centre-point calculations and point-on-line work.

Completing these calculations at the instrument can help operators respond more quickly when design information changes or an unexpected measurement is required. It also reduces manual transcription between calculators, notebooks and separate software packages.

Clear touchscreen and Android operation

The 5.5-inch colour display has a resolution of 720 × 1280 pixels and presents survey information, menus and graphical stakeout guidance in a familiar Android-style interface. A physical 15-key keyboard is also provided for users who prefer buttons for common field commands or need to work while wearing gloves.

The quad-core 64-bit ARM Cortex-A55 processor runs at up to 2 GHz. Standard memory is 4 GB RAM with 32 GB internal storage, with an optional configuration of 8 GB RAM and 128 GB storage. This provides space for project files, drawings, software and collected data.

Flexible data transfer and connectivity

Available interfaces include USB, USB Type-C, Bluetooth, Wi-Fi and RS-232C. An optional 4G module can provide mobile-network connectivity where supported. These communication options make it easier to exchange survey data with computers, controllers and other field equipment.

SurPro 6.0 supports common coordinate and survey data workflows, while drawing layers can include formats such as DXF, DWG, SHP and LandXML. File compatibility should always be checked against the exact software version and the project’s office workflow before deployment.

Designed for everyday site conditions

The ALPHA Y has an IP55 rating for protection against dust and water ingress. Its stated operating temperature range is from -20°C to +50°C, making it suitable for normal outdoor construction and surveying environments when handled according to professional instrument-care practices.

A dual-axis compensator helps correct small setup deviations, while the standard laser plummet assists with accurate centring over a survey point. The 30× telescope provides a clear view of prisms and site features during manual aiming.

Battery performance for a working day

The rechargeable 5,200 mAh lithium-ion battery provides a stated operating time of approximately eight hours at 20°C. Actual endurance will depend on screen brightness, measurement frequency, connectivity, temperature and software use.

For longer shifts or remote projects, carrying a charged spare battery and suitable charging equipment helps maintain uninterrupted field productivity.

Typical ALPHA Y applications

• Building grid, foundation and structural layout
• Topographic surveys and site-detail collection
• Road, utility and civil-engineering stakeout
• As-built measurement and dimensional checks
• Façade, stockpile and inaccessible-point measurement

Who is the ALPHA Y for

The ALPHA Y is suited to teams that need more field capability than a basic manual total station but do not require robotic prism tracking. Its onboard Android software reduces dependence on a separate data collector and gives operators direct access to graphical stakeout, road functions and field calculations.

It is a practical option for construction companies, independent surveyors, engineering contractors, utility teams and educational organisations looking for an integrated total-station workflow with conventional manual aiming.

Buying and support from Global GPS Systems

Global GPS Systems can help buyers review the required angular accuracy, measurement range, software workflow and accessory configuration before selecting the ALPHA Y. Proper setup, compatible data formats, suitable prisms and operator training are important for obtaining reliable results in daily fieldwork.
