We would like to introduce a case study utilizing reference points (star measurement points) through network-type RTK single-point observation in the "Construction of Surveying Work Manual" by the City of Tondabayashi, Osaka Prefecture (in cooperation with Asahi Koyo Co., Ltd.). To conduct 3rd and 4th class reference point surveys, which form the backbone of construction surveying, as public surveys, it is necessary to use higher-level national reference points or public reference points as known points. However, in areas where the density is not sufficiently developed for efficient use, there can be an excessive financial burden. As a result, these surveying works may not be applied to the Geospatial Information Authority of Japan as public surveys, and the surveying results have rarely been utilized beyond the respective projects. 【Solution】 - Developed the RTK-GPS single-point observation method using network-type RTK-GPS in collaboration with Asahi Koyo Co., Ltd. in the field of geodetic surveying. - Received advice from the Geospatial Information Authority of Japan based on the application under Article 16 of the Public Survey Work Regulations. - Utilized the network-type RTK-GPS single-point observation method as public surveying in the field of geodetic surveying. *For more details, please refer to the PDF document or feel free to contact us.

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 we 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 in relation to 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 because RTK-FIX is achieved. *For more details, please refer to the PDF document or feel free to contact us.

We will introduce the differences between conventional positioning methods and network-based positioning methods. Conventional positioning methods include "standalone positioning," which is used for general purposes such as climbing and leisure, and "relative positioning," which is used in cases requiring high accuracy such as surveying. These methods have issues such as accuracy degradation due to various error factors and the need for multiple receivers. The "network-based positioning system" was developed as a solution to these problems, allowing for a maximum accuracy of 1 cm with a single receiver when utilizing this system. Our company has established facilities to enable 24-hour use of network-based positioning throughout Japan and provides this service. 【Features of the Network-Based Positioning System】 ■ Achieves a maximum accuracy of 1 cm with a single receiver ■ Resolves accuracy issues caused by various error factors (standalone positioning) ■ Addresses error problems due to receiver distance (relative positioning) ■ Facilities to enable 24-hour positioning use in Japan *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," since correction information based on electronic reference points is utilized, all tasks related to reference stations, as well as the selection and surveying of fixed points, become unnecessary. Furthermore, as observations are conducted only with mobile stations, it becomes possible for each person to have their own observation equipment, leading to significant cost reductions and allowing for flexible scheduling based on the conditions at the site on the day of work, thus achieving true efficiency. 【Network-based RTK Data Services】 ■ No need for installation and management of fixed points ■ Realization of one observation device per person ■ Achieving over 50% significant cost reduction ■ Two personnel with two receivers can work in a one-person, one-device environment *For more details, please refer to the PDF document or feel free to contact us.
