GNSS View is a free iPhone application developed by NEC Corporation. This travel and navigation app allows users to track the Quasi-Zenith Satellite System (QZSS) in the sky. QZSS is a Japanese satellite positioning system, similar to the American Global Positioning System (GPS). With GNSS View, users can view the position of QZSS and other positioning satellites, such as GPS, in real-time and at specific times and locations.

The app offers three main functions. The Position Radar screen provides a radar view of positioning satellites, including QZSS and GPS, as a sky plot. Users can specify the satellites they want to view and set elevation mask angles to customize the display. The AR Display feature allows users to see the position of satellites through their device's camera, providing a real-time view of the sky from their current location. Finally, users can access the app's operating manual and privacy policy via the website.

GNSS View is compatible with iOS 11 to iOS 16, making it accessible to a wide range of iPhone users. Whether you're curious about satellite positioning systems or need accurate location information, GNSS View is a handy tool to have.
