Yellow Segment
— a satellite is being tracked but is not being used
•
Red
— a satellite is being used to determine a two dimensional (2D) fi x
•
Green
— the satellite is being used to determine your position.
The circle under the satellite segments is green when there is a valid fi x (2D or 3D), and red when there is no fi x.
While a 2D fi x is suffi cient to maintain a valid fi x, a 3D fi x is more accurate.
