Abstract:

Currently, in addition to GNSS receivers manufactured by foreign companies and imported into Vietnam, there are some domestically produced products with lower prices on the market. This paper presents an investigation on the design and development of a low-cost and high-precision GNSS device, used for CORS/RTK measurement in establishing topographic and cadastral maps. The developed GNSS device consists of a GNSS satellite antenna, a receiver, and an electronic field-book (using a smartphone device) installed with a self - developed software. The GNSS receiver is developed based on the technology and equipment of Drotek company (France). The components of the GNSS receiver have been selected and designed with functionality for both dynamic and static measurement modes. The GNSS receiver and electronic field-book are connected wirelessly via the Bluetooth module, allowing convenient operation with the receiver. Experiments were conducted to measure the parallel points of an established geodetic network using GPS technology. The possitioning data was measured by two receivers, South’s S82 (China) and self-developed KX20-R, using RTK method with a single CORS station installed at the University of Mining and Geology. The results showed that the developed GNSS positioning device provides an accuracy of centimeters and completely meet the requirements of large-scale topographic and cadastral surveying and mapping.
