Application Support System for Commercial GPS Receivers
for the Quasi-zenith Satellite System

October 12, 2010 (JST)

Japan Aerospace Exploration Agency (JAXA)

The Japan Aerospace Exploration Agency (JAXA) is beginning a system to support the application of commercial GPS receivers to the Quasi-Zenith Satellite System prior to the start of positioning signal transmission from the First Quasi-zenith Satellite “MICHIBIKI.” The MICHIBIKI was launched from the Tanegashima Space Center at 8:17 p.m. on September 11, 2010 (Japan Standard Time, all the following dates and time are JST.)
This system will provide technical support to receiver/chip manufacturers who are willing to update their commercial GPS receivers that are currently applicable to car navigation and mobile phones to receive and process positioning signals broadcasted from the quasi-zenith satellite system, or who are willing to newly develop a receiver with such a function.

[Support content]

  • To provide a JAXA signal simulator, or to record signals from the simulator using an RF recorder.
  • To provide MICHIBIKI observation data at JAXA monitor experiment stations.
  • To carry out joint evaluation of MICHIBIKI signal reception.
    * The support system this time does not provide direct financial support, but offers indirect support to receiver/chip manufacturers to facilitate their voluntary development efforts.
[Support period]
October 12, 2010 through March 31, 2011

[To receive the support system]
If you wish to use this support system, please download an application format from the JAXA Space Applications Mission Directorate website. The support agreement will be completed when you receive an agreement letter from JAXA.
