ACHIEVING CENTIMETERS-LEVEL GPS POSITIONING ACCURACY USING A SMARTPHONE FOR MAPPING APPLICATIONS

Abstract. Nowadays, GNSS chips inside modern smartphones deliver high-quality code and carrier phase measurements which may be applied in various mobile applications, especially in mapping applications. In this situation, the usefulness of a professional geodetic receiver is commonly met to reach centimeters and sub-centimeter accuracies. To obtain such precise positioning results, carrier-phase measurements should be used. Therefore, we decided to check the Huawei P 30 Pro smartphone GNSS-based positioning system which may be an excellent tool to fast and accurately measure the points or details which may need to be precisely mapped with accuracies within centimeters. According to the tested smartphones' postprocessing RTKLib 2.4.3 software results, we could fix all L1 ambiguities based on GPS-only satellite constellation. After the comparison to reference fixed point position, for all 1-hour static session results, positioning errors were at centimeters level of accuracy (1-5cm). For fast static surveying mode, the best results were obtained for 30-minute sessions, where average accuracy was also at centimeters level (close to the level of a professional geodetic receiver).
