RTK technology, i.e. carrier phase differential technology, the abbreviation comes from Real-timekinematic, meaning real-time dynamic differential. In Junoda GPS/RTK + antenna fusion positioning system, RTK technology is mainly used in chemical industry, construction sites, hospitals, welfare institutions and other industry scenes to provide high-precision positioning services. In this article, we mainly come to understand some influencing factors for mobile station to enter RTK state.

I. Common satellite-related influencing factors

Common influencing factors mainly come from the following three points: 1. air factor, such as the weather difference between the fixed station and the mobile station is huge; 2. electromagnetic interference, such as the mobile station is close to high-voltage electricity and other strong sources of interference in the process; 3. geographic environment, such as the mobile station is close to the movement of tall buildings, windbreak forests, and a large area of water, and so on.

Influencing Factors of RTCM Differential Data

The common influencing factors in this area are: 1. Distance factor, the farther the distance the weaker the broadcast signal strength, the worse the positioning accuracy; 2. Electromagnetic interference, the bigger the interference, the smaller the broadcast range and the effective range; 3. Geographic environment, the more complex the environment (not open), the greater the impact on RTCM differential data.

 Global Positioning System (GPS), a positioning system based on artificial Earth satellites with high-precision radio navigation, is widely used in many industries such as transportation, surveying and mapping. However, the positioning accuracy of ordinary GPS is more than 1 meter, and there is a 50% probability that the signal error will reach more than 2 meters, and this accuracy is far from meeting the requirements in the application of intelligent parking. And RTK technology as a differential GPS in a higher precision, can meet the higher positioning needs.

Junoda technician GPS/RTK + antenna fusion positioning system, relying on the industry's outstanding wireless communication experts and data security development team, the use of Internet of Things, cloud computing, big data, algorithm engine and other advanced technologies, fusion GPS/RTK differential positioning technology, can be applied to more fields and scenes, in order to ensure the positioning accuracy under the premise of substantial cost savings, greatly enhance the enterprise safety production management Intelligent level.
