In complex environments, such as urban canyons, densely packed buildings, areas with severe electromagnetic interference, and places with complex and changeable terrain such as mountainous areas, the high precision GNSS RTK (real-time dynamic differential positioning) development board faces many challenges, and how to maintain stable signal reception has become a key issue. In order to ensure that high-precision and reliable positioning services can still be provided in these environments, the high precision gnss rtk development board adopts a variety of technologies and strategies.
First, in response to the problem of signal blocking, the high precision gnss rtk development board is usually equipped with a multi-band, multi-constellation receiving module. This means that they can receive signals from different satellite navigation systems (such as GPS, GLONASS, Galileo, BDS, etc.) and use signals from multiple frequency bands for positioning and navigation. Multi-band reception can enhance signal penetration and reduce signal loss caused by building blocking, tree shielding, etc. At the same time, multi-constellation compatibility increases the number of available satellites and improves the continuity and accuracy of positioning.
Secondly, in order to deal with electromagnetic interference, the high precision gnss rtk development board integrates advanced anti-interference algorithms and technologies. These algorithms can effectively distinguish and suppress interference signals in complex electromagnetic environments, ensuring accurate detection and tracking of satellite signals. In addition, the development board may also use hardware designs such as low-noise amplifiers and high-gain antennas to further improve the sensitivity and stability of signal reception.
In addition to the above technologies, the high precision gnss rtk development board also reduces the impact of multipath effects by optimizing signal processing algorithms. Multipath effects refer to the positioning error caused by the reflection or refraction of satellite signals encountered by obstacles (such as buildings, ground, etc.) during propagation, and the superposition of signals directly from satellites. By adopting advanced signal processing algorithms, such as multipath suppression technology, the development board can identify and eliminate these interference signals, thereby improving the accuracy and reliability of positioning.
In summary, the high precision gnss rtk development board maintains stable signal reception in complex environments through a variety of technologies and strategies such as multi-band, multi-constellation receiving modules, advanced anti-interference algorithms and technologies, and optimized signal processing algorithms.
