GNSS View

This application enables you to see where the Quasi-Zenith Satellite System (four-QZS constellation) in the sky！

●What is QZSS？

In addition to the first QZS "Michibiki", you can also see the four-satellite-constellation QZSS which will be operated from FY2018.

The positioning satellites displayed in the GNSS View are not based on the satellite information directly received by the smartphone but are displayed based on the satellite arrangement calculated based on the publicly released orbit information.

●GNSSView 3 functions
【Main】
・You can move to the Position Radar screen or AR Display screen from the application startup screen.

【Position Radar】
・It is provided radar view of positioning satellites such as QZS and GPS as a sky plot at the specified time and location.
・Positioning satellites can be specified from QZSS, GPS, GLONASS, BeiDou, Galileo, SBAS.
・You can also select specified signal satellites to see on the radar.
・You can see selected satellites by setting elevation mask angle.
・You can switch east and west of satellite arrangement, turn on / off rotation, and switch on / off display of satellite number.
・It displays HDOP, VDOP, the total number of satellites and the number of each positioning satellites in the satellite arrangement displayed on the radar.

【AR Display】
・Position of positioning satellites such as QZSS and GPS on the sky from your current location is able to see through your android camera at the specified time.
・In order to display satellites, it is necessary to turn on the position information of the smartphone and complete the positioning. Therefore, it may take time to display.
