Introduction

To establish a GNSS global cooperative network, Multi-GNSS Integrated Real Time and Archived
Information System “MIRAI” has been built by the Cabinet Office (CAO). Figure 1 shows thesystem diagram of MIRAI. This system provides the following services;Collecting real-time observation data and redistributing them to public users.

Archiving observation data and redistributing them to public users.

The objective of this proposal is to establish the GNSS global cooperative network by supporting
current GNSS tracking network operators.
