◆SOFTBANK（ichimill）
"Ichimill" is a high-precision positioning service that has been introduced by over 800 companies.
ichimill is a service that enables advanced positioning with an error of a few centimeters by performing RTK positioning using signals received from GNSS such as the quasi-zenith satellite "Michibiki".
With general GNSS (GPS), the positioning error is around 5m to 10m, but SoftBank distributes "correction information" via the network.
By performing RTK positioning calculations using the signals received by the GNSS receiver, real-time positioning with an error of several centimeters is possible.


<Establishing high-density original reference sites>
By utilizing its own base station installation locations, SoftBank has installed its own reference sites (fixed stations) required for RTK positioning in more than 3,300 locations nationwide.
No reference site preparation is required by the customer.

<Stable positioning is possible even when moving over a wide area>
Because reference sites are deployed at a high density throughout the country, stable positioning can be achieved with very short switching times (handovers).
Continuous high-precision positioning is possible even when traveling long distances, such as crossing reference sites.

◆ALES

■Centimeter-level positioning service (for individual customers)
<Real-time data distribution (Ntrip method)>
Correction information generated by the "ALES distribution system" using observation data provided by SoftBank Corp.will be distributed to the customer's GNSS receiver via the Internet (Ntrip).
By using this correction information, this service enables highly accurate positioning with an error of a few centimeters in real time.

■Post-processing data service (for corporate customers)
<File download method>
This is a service that provides corrected data generated based on observation data from unique reference sites provided by SoftBank Corp. in file format (RINEX) for post-processing.
Highly accurate positioning is possible by performing post-processing using observation data acquired by the customer's GNSS receiver and this data.

◆CSESS

This consortium aims to commercialize research results in the field of earth science and create new earth sciences by utilizing data from SoftBank's high-density GNSS observation network (unique reference sites).
The center of our activities is the verification of data utilization methods in a wide range of earth science fields, such as earthquakes and meteorology, and is expected to greatly contribute to the prediction of natural disasters and disaster prevention and mitigation.
SoftBank and ALES plan to make proposals for commercialization and disaster prevention/mitigation based on the research results.
The consortium will also advance research in fields such as earthquakes, volcanoes, meteorology, and the ionosphere.
