Industry application

Application areas and industries:

It is widely used in all fields such as land survey and management, forestry census,aerospace, military, logistics and transportation, resource exploration, communication meteorology, power and energy,surveying and mapping industries.

In the surveying and mapping industry, RTK can be used in engineering surveying, deformation observation, aerial photogrammetry, oceanographic surveying and geographic data collection in geographic information systems.

With the measurement software, it can carry out engineering measurement operations such as tunnel measurement, road design, earthwork calculation, area measurement, and power exploration.Connect the CORS base station and account to receive the signal and start the measurement operation.

Advantages of RTK

RTK has high measurement accuracy; easy operation, small size of the instrument, easy to carry; all-weather operation; no need to see through between observation points; measurement results are unified under WGS84 coordinates, information is automatically received and stored, reducing tedious intermediate processing links, high efficiency and other notable features, won the trust of the majority of surveying and mapping workers.

Compared with traditional advantages

Compared with traditional geodetic surveys that using triangular nets and wire nets to measure, which is not only labor-intensive and time-consuming, but also requires visibility between points, and the accuracy is unevenly distributed, and the accuracy is unknown in the field. GPS static measurement, fast static, and pseudo-dynamic methods cannot know the positioning accuracy in real time during the field measurement and design process. If the measurement and design are completed, and the accuracy is found to be unsatisfactory after returning to the office for processing, the measurement must be returned, and RTK is used for the measurement. Control the measurement and know the positioning accuracy in real time. If the point accuracy requirements are met, the user can stop the observation and know the quality of the observation, which can greatly improve the operation efficiency. If RTK is used for highway control measurement, power line measurement, hydraulic engineering control measurement, and geodetic survey, it can not only greatly reduce save labor costs, but also greatly improve work efficiency, measuring a control point in minutes or even seconds can be completed within.

Compared with traditional advantages

Topographic mapping In the past, when surveying topographic maps, it was generally necessary to first establish a point control point in the survey area, and then put a total station or theodolite on the point control to cooperate with a small flat-panel survey. Now it has developed to field total station and electronic The handbook cooperates with the feature code, and the large-scale mapping software is used for mapping, and even the development of the recent field electronic flat-panel mapping, etc., all require the measurement of the surrounding land and other parts on the station. All points are in line with the measuring station, and generally at least 2-3 people are required to operate. It is necessary to return to the field for re-measurement if the accuracy does not meet the requirements during the jigsaw puzzle. When RTK is used, only one person is required to carry the instrument on the back of the landform to be measured. Stay for a second or two at the spot, and input the feature code at the same time. You can know the accuracy of the point in real time through the handbook. After measuring an area, return to the room, and the professional software interface can output the required topographic map. In this way, only one person is required to use RTK to operate, and it does not require point-to-point visibility, which greatly improves work efficiency. Using RTK and electronic handbook can measure and design various topographic maps, such as ordinary surveying maps and railway line strip topographic maps. The survey and design of the road pipeline topographic map, together with the echo sounder, can be used to measure the reservoir topographic map, nautical ocean survey and so on.

Compared with traditional advantages

Construction stakeout is an application branch of measurement. It requires a certain method and a certain instrument to calibrate the artificially designed points in the field. In the past, many conventional stakeout methods were used, such as the theodolite intersection stakeout, total station edge and corner stakeout, etc. Generally, when setting out a design point, it is often necessary to move the target back and forth, and 2-3 people are required to operate it. At the same time, during the stakeout process, it is also required that the point-to-point visibility is good, and the application efficiency is low. Sometimes If you encounter difficulties in staking, you will use many methods to stake out. If you use RTK technology to stake out, you only need to input the designed point coordinates into the electronic handbook, and carry the GPS receiver on your back, it will remind you to go The position of the staked point is fast and convenient. Since GPS directly stakes out the coordinates through coordinates, and the accuracy is very high and uniform, the efficiency of stakeout in the field will be greatly improved, and only one person is required to operate.
