## Significance of the Basic Law

**Significance of the Basic Law**
**      ****(1)**** To specify clearly the Definition under the Basic Law;**
**            ****・ ****What is ****『****Geo-Spatial Information****』 ****(****NSDI****)**
**            ****・ ****What is ****『****GIS****』 ****(****Geographical Information System****)**
**            ****・ ****What is ****『****Space-based PNT****』**
**      ****(2)**** Importance of NSDI through synergistic effects of  **
**           ****the measures for GIS and Space-based PNT**
**    ****(3)**** Restructuring of communication and coordination **
**          ****framework among the related Ministerial Offices**

## To communicate and coordinate with GNSS providers

**Study on the system to deliver such information on operating status, etc of GNSSs must be conducted**

**For stable utilization of GPS in Japan**

- PNT in Japan is totally dependent on Others

- Periodical get together of “US-Japan GPS Talk”

**To communicate and coordinate with GNSS providers**

- Car-Navi

- Surveying

- Transportation

- PND

- PNT is widely utilized in Japan

- It is imperative to secure effectively the environment to obtain reliable GNSS services in a stable manner

- Useful information such as satellite unhealthy must be provided to people

**Communication and coordination with the operators of GNSSs must be made**

**○****Use of PNT depends heavily on GPS**

**○****Status information of GNSS providers ****(****GPS, GLONASS, Galileo etc****)**** is needed**

**Participation to the UN ****ICG ****and providers forum**

**As J-Government, to promote coordination and cooperation among GNSS provider countries**

- GPS : Global Positioning System

## The main Role of the Government

**The main Role of the Government**
**  ****A.****  ****The Government of Japan will ****study****;**
**      ****(1)**** ****The architecture and its management system for ****strategic **
**             ****promotion**** of effective and efficient implementation, update, **
**             ****provision and proliferation of Geo-Spatial Information,**
**     ****(2)**** ****The materialization of the space-based PNT service through QZSS,**
**         **
**     ****(3)**** ****The business model to make use of Geo-Spatial Information.**
**  ****B.**** ****The Government of Japan will ****review**** the promotional structure for  **
**        ****Geo-Spatial Information utilization in line   with the ideology of the **
**        ****Basic Law, whereas in case of promotional structure for space-based **
**        ****PNT, the Government of Japan will also take into account the trends **
**        ****of ****Space Development and Utilization Policy**** as necessary.**

## Acceleration of R&D for GNSS Utilization and Technology

- ○ **GNSS** **Utilization by the Government Organizations**

- Tracking of law enforcement officers and helicopters

- Navigation aid by National Defense Force

- Digital map ledger

- Seismic survey and research

- Robotic precise agriculture、Study on marine animals behavior

- Information supply for GPS augmentation to secure safety of air and maritime traffic

- Collection and supply of GPS observation data by GEONET

- ○ **GNSS** **Utilization by Municipal Governments and private sectors**

**Obstacle by elevated**
**building**

**QZSS**

**Angle of GEO**
**45 degree**

**Angle of QZSS 80 degree**

**Orbit of QZSS**

**Angle of MEO 70 deree**

**Realization of high-precision positioning services free of multi-pass effects at urban cannons etc to cover entire national land with the constellation visibility close at 12 o’clock high**

- Concept of QZSS

**Major feature is the provision of high precision PNT in entire Japan**

## The main Role of the Government (2)

**The main Role of the Government ****(****2****)**
**  ****C.  Utilization of Geo-Spatial Information by Ministry**
**      ****Respective ****ministerial office will promote utilization of Geo-Spatial **
**       ****Information by making the effectiveness of GIS****/****S****pace-based PNT**** utilization **
**       ****widely known, for such fields where the municipal governments, etc. may **
**       ****attain efficiency and sophistication enhancement of their activities by making **
**       ****use of GIS ****/****S****pace-based PNT****.**** **
**     **

## Measures for Space-based PNT

**Measures for Space-based PNT**
**  ****A.  To secure the environment to obtain reliable PNT**
**  ****(1)**** ****Communication and coordination with GNSS providers:   **
**       ****The Government of Japan will communicate and coordinate with **
**       ****the US Government to realize stable utilization of GPS in Japan through as **
**       ****far as possible periodical meeting of US - Japan GPS Talks, where relevant **
**       ****issues for GPS utilization is discussed based on "The Joint Statement of  the **
**       ****both Government as to Utilization of GPS" of September, 1998. **
**       ****The Government of Japan will participate the ICG established by COPUOS, **
**       ****and the GNSS Provider Forum to gather information on the development and **
**       ****utilization of GNSS in the relevant countries ****(****GPS, Russian GLONASS and **
**       ****EU Galileo****)****, in addition to strengthening of the relationship between Japan **
**       ****and the GNSS provider nations by taking the use of GNSS from various **
**       ****nations into consideration. **

##   (2) Information Supply for Improvement of Space-based PNT Utilization:        

**  ****(2) ****Information Supply for Improvement of Space-based PNT Utilization:        **
**      ****The Government of Japan will study and take necessary measures based on the**
**      ****conclusion of such study, proper system to provide the relevant users with**
**      ****information on the operational conditions of GPS for reliability and stable**
**      ****availability.**
** **
**  ****B. ****Basic Concept of R&D for Space-based PNT:**
**    ****The Government of Japan will undertake R&D mainly for the complementary**
**     ****space-based PNT system, while the private sector will conduct R&D for the**
**     ****augmentation system; provided, however, that the Government of Japan will be**
**     ****involved in high-risk R&D by the private sector, in consideration of the present**
**     ****conditions wherein Satellite Positioning is widely used for the people's life, and**
**     ****in recognition of needs for Japan to establish the technical foundation of space-**
**     ****based PNT, as well as keeping in mind active utilization of private sector**
**     ****resources and fostering of private sector industry.**** **** **

##   The next step  

**  ****The next step**** **** **
**    ****To establish the Basic Law for the Space Utilization**
**     ****which being under discussion at the LDP.**
