GNSS View 5.0.2

This application allows users to visualize the Quasi-Zenith Satellite System satellite positions in the sky.

• What is QZSS?
  Quasi-Zenith Satellite System (QZSS) is a Japanese satellite positioning system that primarily consists of satellites in quasi-zenith orbits (QZO). These systems utilize satellite signals to determine location information. An equivalent system is the famous American Global Positioning System (GPS), with QZSS often being referred to as the Japanese GPS.
• What is GNSS View?
  GNSS View is an iOS application based on the web application "GNSS View." Through this app, users can track the positions of positioning satellites such as QZSS and GPS at a specified time and location. The positioning satellites shown in GNSS View are calculated based on publicly available orbit information, rather than directly received by the smartphone.
• GNSS View 3 functions
  • Main:
    • Users can navigate to the Position Radar screen or AR Display screen from the application's startup interface.
    • Access the operating manual and privacy policy through the accompanying website.
  • Position Radar:
    • Radar view of positioning satellites such as QZSS and GPS as a sky plot at the user-specified time and location.
    • Select positioning satellites from QZSS, GPS, GLONASS, BeiDou, Galileo, SBAS.
    • Customize views by choosing specific signal satellites and setting elevation mask angles.
    • User control options include switching east and west satellite arrangements, enabling rotation features, and toggling satellite number displays.
    • Showcases HDOP, VDOP, total number of satellites, and individual counts of each positioning satellite in the radar display.
  • AR Display:
    • View positioning satellites like QZSS and GPS through your camera at a specified time relative to your current location.
    • To display satellites accurately, smartphone position information must be enabled and position determination completed. This process may lead to some delay in display.
    • Select specific signal satellites for viewing and adjust settings for elevation mask angles.
• Supported versions
  iOS 17, iOS 16, iOS 15, iOS 14, iOS 13, iOS 12
