Bài viết này trình bày nghiên cứu phát triển máy định vị GNSS giá thành thấp, có độ chính xác cao, sử dụng để đo đạc theo kỹ thuật CORS/RTK trong thành lập bản đồ địa hình và địa chính. Máy định vị GNSS được phát triển gồm: Ăng ten thu tín hiệu vệ tinh GNSS, bộ thu và sổ đo điện tử (sử dụng smartphone) được cài đặt phần mềm tự thiết kế phát triển. | Journal of Mining and Earth Sciences Vol. 63 Issue 1 2022 63 - 72 63 Investigation in designing and developing the GNSS positioning instrumentation used in measurement and mapping by CORS RTK technology Khai Cong Pham 1 Hai Van Nguyen 2 Nghia Viet Nguyen 1 1 Faculty of Geomatics and Land Administration Hanoi University of Mining and Geology Vietnam 2 Faculty of water Resources Engineering Thuyloi University Vietnam ARTICLE INFO ABSTRACT Article history Currently in addition to GNSS receivers manufactured by foreign Received 15th May 2021 companies and imported into Vietnam there are some domestically Accepted 23rd Nov. 2021 produced products with lower prices on the market. This paper presents an Available online 28th Feb. 2022 investigation on the design and development of a low-cost and high- Keywords precision GNSS device used for CORS RTK measurement in establishing GNSS receiver topographic and cadastral maps. The developed GNSS device consists of a KX20 - R GNSS satellite antenna a receiver and an electronic field-book using a smartphone device installed with a self - developed software. The GNSS RTK KX Rover receiver is developed based on the technology and equipment of Drotek ZED - F9P. 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 .
