In the verification of network-type RTK-GPS on the barge, it was difficult to obtain a FIX solution due to the influence of unloading arms and cranes as one approached the barge, making it unsuitable for precise guidance. This time, we compared the positioning accuracy of RTK positioning using network-type GNSS distribution with GPS only and examined the usefulness of multi-GNSS regarding the impact of surrounding structures. 【Results】 ■ Multi-GNSS consistently has more received satellites than GPS. Therefore, the impact on positioning accuracy due to satellite switching is minimal. ■ Distribution of positioning results for GPS and multi-GNSS when there are few obstructions. Multi-GNSS shows smaller dispersion and standard deviation in the horizontal plane (2D), resulting in higher positioning accuracy. ■ Distribution of positioning results for GPS and multi-GNSS when there are many obstructions. Multi-GNSS has greater dispersion and standard deviation in the horizontal plane (2D) compared to when there are few obstructions. While the positioning accuracy is slightly lower, it is still higher than the FLOAT of GPS only since RTK-FIX is achieved. *For more details, please refer to the PDF document or feel free to contact us.

I will introduce the benefits of network-based GNSS positioning in the surveying field. Network-based GNSS positioning includes "RTK data services" and "post-processing data services." In the case of "RTK data services," it utilizes correction information based on electronic reference points, eliminating the need for any work related to reference stations, the selection of fixed points, or field surveys. Furthermore, since observations are conducted only with mobile stations, it allows for one observation per person, leading to significant cost reductions and enabling flexible scheduling based on the day's site conditions, thus achieving true efficiency. 【Network-based RTK Data Services】 ■ No need for the installation and management of fixed points ■ Achieves one observation per person ■ Realizes over 50% significant cost reduction ■ Two personnel with two receivers can work in a one-per-person environment *For more details, please refer to the PDF document or feel free to contact us.
