Device application
>Construction lofting
The rich point and line setting function, supplemented by graphical operation guidance, can save more cost for the construction of your project
>Power traffic
Convenient power direction measurement, distance measurement and angle calculation; comprehensive and practical highway survey, middle pile, side pile measurement, longitudinal and cross section measurement function
>CORS application
For the application of CORS system, only one RTK mobile station can receive CORS differential signal for data acquisition, construction layout and so on.
>CORS station
HD-CORS integrated the mature technology of Zhong Haida for many years, and has the advantages of stable operation and long transmission distance. It is the preferred solution for the city continuous reference station system.
>Control measurement
One investment, multiple functions, iRTK dual frequency static measurement accuracy to meet any control survey requirements, supporting mature professional data solver software, can help you complete all kinds of high-precision control survey work.
>Data acquisition
Handbook operation software designed for GIS system, flexible coding function to meet your fast and efficient field data acquisition needs
> water measurement
Equipped with the marine survey, marine mapping software and depth sounder of Haida's surveying and Mapping Authority, the underwater topography survey can be carried out easily, and the traditional operation mode of water survey is completely changed.
>Construction location (water)
The iRTK system helps you to accurately complete the marine engineering, such as riprap, paving and piling, to meet the special requirements of marine engineering.
