Abstract
The GNSS signals will be refracted when going through the neutral atmosphere and the ionosphere, with the speed change and signal curve. The effects are called GNSS atmospheric and ionospheric delays, respectively. In addition, the GNSS antenna can receive signals from not only the direct path, but also indirect reflected or diffracted signals, which will result in a certain delay, phase, and amplitude difference relative to the direct component, called GNSS multipath effects. In this Chapter, more detailed atmospheric delays and multipath effects are introduced, including tropospheric and ionospheric correction models and multipath variation characteristics with satellite elevation and antenna height.
