Comparing Multicarrier Ambiguity Resolution Methods for Geometry-Based GPS and Galileo Relative Positioning and Their Application to Low Earth Orbiting Satellite Attitude Determination

Figure 2

Typical ground track for ENVISAT shown in magenta with the Galileo constellation. The circle containing the black cross indicates the initial ENVISAT location (∼80^∘S, ∼60^∘W). The GNSS satellites are labelled by PRN number. The blue portion of their ground tracks indicates the GNSS satellite is being used in the solution.
