Trimble GNSS Planning Online

The Trimble GNSS Planning Online web-based application (www.gnssplanningonline.com), which is accessible from the the File > Tools menu, is an extremely useful tool in determining the best period of time to collect GNSS data. Simply select your location; date, time, and duration; and constellations used by your receiver. The application provides the maximum count of visible satellites, the best satellite geometry, and the best ionosphere conditions using easy-to-read charts and graphic displays.
