Comparison analysis of accuracy and precision on GNSS K706 Oem Board and GPS Topcon HiperPro

Abstract

GNSS technology has been widely used in the field of surveys and mapping. According to Abidin this is because GNSS can be used regardless of time, is not affected by the topography of the survey area, and provides accuracy with a wide spectrum. GNSS technology also has several disadvantages, one of which is price. The tool used to implement GNSS technology has a high price, for example is the geodetic type which has prices ranging from hundreds of millions of rupiah. The last few years have found low-cost GNSS. which has a cheaper price. To find out the quality of low-cost GNSS a test was carried out. In this study a low-cost GN70 Oem Board was tested. This study focuses on testing accuracy and precision. The method used for testing is RTK, and Static for data as a reference. RTK data acquisition uses the NTRIP method with CORS Surabaya as the base. There are 3 test locations in this study. The first is in BM01ITS or "bits". Both the ITS Stadium or "bstd", and third Sakura Park or "bskr". Horizontal and vertical deviation standards on the K706 OEM board has better quality than Topcon HiperPro. This is evidenced by the standard deviation of the K706 superior in 4 research points, while HiperPro only excels at two research points. Horizontal RMSE both devices have the same quality. This is evidenced by the RMSE of the K706 superior in 3 research points, and HiperPro excels in 3 research points. For vertical RMSE, the K706 is better than HiperPro. This is evidenced by the standard deviation of the K706 superior in 5 research points, while HiperPro only excels at one research point.
