RTK technology is a positioning technology. RTK and GPS have similar functions, but they cannot be used interchangeably.
What is RTK technology and how is it different from GPS technology?
In recent years, RTK technology has developed rapidly and has played an important role in various fields such as control, topographic mapping, and engineering stakeout. Many people think that GPS technology is enough for positioning, so why use RTK technology?
GPS is mainly used to measure the distance between satellites with known positions and user receivers, while RTK is mainly used to deal with the different problems of carrier phase observations of two measuring stations. The principles of the two are different, and the effects are also different.
In terms of GPS application, measurement is only a small branch. At present, the circulation of measurement knowledge is limited, and the professionalism of measurement personnel is not high. Using GPS measurement will affect the measurement efficiency. The use of RTK technology will have more prominent advantages in the measurement method.
How to set up RTK base stations, these matters need to be known
RTK is a kind of positioning system, and the base station is an essential part of RTK. The quality of the RTK base station erection will directly affect the performance of the equipment. So, how to set up the RTK base station?
1. The base station of RTK should be erected to ensure that the sky is open, and there should be no large obstacles above the 15° height angle. This ensures the accuracy of the satellite signal.
2. The base station of RTK should be set up to avoid the interference of electromagnetic waves. Such as TV towers, microwave stations, high-voltage transmission lines, transformer stations, etc. cannot appear near the base station of RTK.
3. The RTK base station should be set up at a high place so that the working distance of the equipment is farther. Generally speaking, the higher the base station of RTK is, the farther the working distance is.
4. RTK base stations should be far away from places with a strong reflection of electromagnetic wave signals, such as water areas, high-rise buildings, etc. Once the signal reflection is strong, multi-path effects will occur, which will affect the use of RTK.
Therefore, if you want to set up an RTK base station, you must pay attention to the above matters, so as to ensure that RTK has a better effect.
