An app that shows positioning satellite placement
GNSS View is software that reproduces satellite placement in the sky (constellations) at a given time and location based on publicly released orbital information for positioning satellites.
(Released in 2014)
Easily display satellite positions at a given time and place
This app displays the current location and time by default, but the set time can be modified to view changes in satellite placement.
Supports six satellite positioning systems
This app can display satellite placement for six satellite positioning systems, including Michibiki, GPS, GLONASS (Russia), BeiDou (China), Galileo (Europe), and the Satellite-based Augmentation System (SBAS). The four systems other than Michibiki and GPS are calculated based on publicly available orbital information from the North American Aerospace Defense Command (NORAD).
