Publish Time: 2025-03-31
High precision GNSS RTK (Global Navigation Satellite System Real-Time Kinematic) technology, with its centimeter-level or even millimeter-level positioning accuracy, plays a vital role in many fields such as surveying and mapping, construction engineering, agriculture and water conservancy projects. The realization of this technology is inseparable from the high-performance GNSS RTK development board, and data storage capacity is one of the important indicators to measure the performance of the development board.
After receiving the observation data from the satellite, the GNSS RTK development board will process and store the data in real time for subsequent analysis. These data include satellite signal strength, carrier phase observations, pseudo-range observations, etc., which are essential for achieving high-precision positioning. Since GNSS RTK technology needs to continuously receive and process a large amount of satellite data, the data storage capacity of the development board directly affects the real-time and stability of the system.
In terms of data storage, GNSS RTK development boards usually adopt a strategy combining multiple storage methods. On the one hand, the development board will be equipped with a certain capacity of built-in memory for temporary storage of received satellite observation data. These memories usually have high read and write speeds to ensure that data can be written and read in real time. On the other hand, the development board also supports external storage expansion, such as using storage devices such as SD cards and USB flash drives to further increase storage capacity.
It is worth noting that the GNSS RTK development board also considers the format and standardization of data when storing data. Since the raw data formats generated by GNSS receivers of different manufacturers and models are different, this brings difficulties to the unified processing and analysis of data. To solve this problem, the industry has introduced standard data formats such as RINEX (Receiver Independent Exchange Format). The RINEX format has now become the standard data format for GNSS measurement applications. It supports data storage of multiple satellite systems (such as GPS, GLONASS, BeiDou, Galileo, etc.) and has high compatibility and readability. GNSS RTK development boards usually support data storage in RINEX format to ensure standardization and unified processing of data.
In addition to data storage capabilities, GNSS RTK development boards also need to have efficient data processing capabilities. This includes steps such as data preprocessing, filtering, and solution to extract high-precision positioning information. At the same time, the development board also needs to support real-time communication functions so that the positioning results can be transmitted to the user end or control center in real time. The realization of these functions requires powerful hardware support and optimized software algorithms.
In summary, high precision GNSS RTK development has demonstrated outstanding capabilities in data storage. By combining built-in memory with external storage expansion, and supporting standard data formats such as RINEX, the development board can efficiently store and process a large amount of satellite observation data. At the same time, the development board also needs to have efficient data processing capabilities and real-time communication functions to meet the needs of high-precision positioning applications. With the continuous advancement of technology and the continuous expansion of application fields, the data storage capacity of the GNSS RTK development board will be further improved, providing strong support for high-precision positioning applications in more fields.
