The first is next. Instrument will make the correction automatically after then temperature and atmospheric pressure are input.
The second may be following. Data measured by Distance Meter will be transferred automatically to the Electronic Theodolite. The slope distance, horizontal distance and elevation difference will be displayed directly.
Electronic Theodolite carries out coordinate’s measurement and display X, Y, Z coordinates value of the point. It carries out the staking-out measurement conveniently.

Combined total station is next generation

Combined total station and GPS framework is to embed the GPS into the total station functionality. The benefits of such a system are many:

  • improved productivity,
  • reduced learning curves (since surveyors would theoretically need less detailed knowledge about GPS operation because much of it is automated)
  • setup flexibility to meet a wide range of applications.

The combined total station survey tool designed to maximize a surveyor’s efficiency during routine tasks such as boundary surveys or construction stakeout. With its combined total station and GPS capabilities, it eliminates the need for lengthy traverses and multiple setups by integrating GPS into a total station.  Total station with GPS capabilities is a complete survey instrument that has the intelligence together and process RTK GPS data.

The key elements of the GPS total station is dual-frequency GPS receiver. This advanced GPS technology is mounted directly on the total station. It is able to acquire all visible satellites and work in less than perfect conditions. These instrument owners can also take advantage of these new features.

In urban areas satellite visibility was a problem. Local geography can limit the exclusive use of GPS to complete a survey. In many cases, GPS is used to establish control while total stations are used to complete the remaining areas. In many cases, given that a GPS reference station is operating in the vicinity and transmitting RTK corrections, RTK GPS can be used to establish control points. With combined total station, this survey would be conducted by setting it up in a convenient location and determining the coordinates with RTK GPS. A back sight can then be observed to a second unknown point, but is not yet coordinated. All necessary detail is observed from the current location before relocating to the second point. Back sight point doesn’t have coordinates (yet), there would be no coordinates for these detail points. Once set up at the second point, its coordinates are now determined with combined total station RTK GPS. The availability of this second coordinate then allows the system to automatically update all observations made from the first setup. All detail observed from the second point can be immediately stored in the coordinate system created from the two GPS observations.
