Technical Information: Accuracy Verification of RTK (Why is RTK said to be within 10km?)

■ FaceMe Security "Visitor Access Management" Key Features and Characteristics < Set Access Periods for Each Visitor > - Individual settings for the dates and times visitors can enter - Optimal access periods can be set according to the visitor's situation, whether for short visits or long stays. < Two Types of Authentication Methods to Accommodate Various Scenarios > ▶ Authentication via IP Camera - Enables authentication from a distance, achieving facial recognition without the need to disembark. ▶ Authentication via Facial Recognition Device (e.g., tablet) - Ideal for entry scenarios such as reception or security posts. Can be flexibly utilized depending on the installation location and operation. - Allows for on-the-spot registration of facial information using the device, enabling smooth responses to sudden visits or unexpected guests. < Real-Time Notifications Supporting Security and Reception Operations > - Real-time notifications of visitor and employee classifications, authorization expiration, and authentication status. - Prevents delays and oversights in verification, balancing the reduction of security staff workload with enhanced security. These features resolve issues arising from visual checks, logbooks, and IC card operations, simultaneously achieving enhanced security and improved efficiency in reception and security operations.

Do you have any concerns or requests regarding wired bed exit sensors? × Tangling or tripping over wired cables × Cable disconnection or damage × Worrying about forgetting to turn the switch back on after temporarily stopping the sensor. × Wanting to be notified of bed exits even from a location far from the nurse call outlet. Such concerns can be resolved simply by connecting our wireless nurse call linked set to the sensor! Our wireless nurse call linked set allows you to connect bed exit sensors like "Ugo-kun," "Foldable Thin Matta-kun," "Ayumi-chan," and "Just Place Pole-kun" to transmitters and receivers, reducing wiring around the bed area, alleviating concerns about tripping or falling due to cables, and contributing to a tidier work environment. Furthermore, it enables the use of bed exit sensors even from locations far from the nurse call outlet, allowing for more flexible equipment placement.

A system for driver terminals has been realized through API integration, promoting the optimization of the delivery process and improvement of services to customers. Seino Information Service Co., Ltd. and Briskola Co., Ltd. announce that they have adopted Briskola's full lifecycle API management product "BAMs Series" for the construction of a system utilizing APIs and the management of API connections with various business applications for driver terminals, aimed at improving delivery efficiency and achieving digitalization of logistics for Seino Transportation Co., Ltd. and transportation groups nationwide. By implementing Briskola's "BAMs Series" for API management in the delivery management system constructed through API integration, we will focus on responding to the expected increase in the number of API calls due to the anticipated increase in terminal numbers, as well as ensuring stable system operation and preventive detection. This will lead to improved operational efficiency for drivers and the provision of high-quality services to customers sending and receiving packages.

In this case study, we have received cooperation from Obayashi Corporation and Sankyu Inc., leaders at the forefront of the construction and logistics industries, to introduce their specific initiatives regarding "early detection of heatstroke risk" and "ensuring worker safety." Additionally, we have published an interview article with Obayashi Corporation, who contributed to the development of "GenVital LTE," as a "development story." As heatstroke risk has become a social issue, we encourage everyone in companies working on improving on-site productivity and safety measures for workers to read this for insights. GRIFFY will continue to contribute to creating safer and more comfortable working environments through DX solutions, including "GenVital LTE." ◾️ Obayashi Corporation (case study) ◾️ Sankyu Inc.

We conducted an RTK accuracy verification of the GNSS reference station (Hi-Target Vnet6plus receiver + choke ring antenna) installed at our company building. Generally, with a single-frequency GNSS, once the baseline length exceeds 10 km, it becomes impossible to consider the path through the ionosphere as the same, and the difference in ionospheric delay becomes a significant source of error. By using dual-frequency GNSS, it is possible to correct the delay based on the differences in delay caused by the frequency of the radio waves; however, it is still said to be effective only up to about 10 km. Why is that? We have published the verification results on our blog.
