Satellites Page

The Satellites Page displays GPS and satellite information, time, and elevation.

Constellation and Signal Graph
Both the satellite constellation and the satellite signal graph display visible satellites and their identifying numbers. The
satellite constellation depicts each satellite's position and the signal graph bars indicate the strength of each satellite
signal.
The icons in the satellite constellation and the bars in the signal graph are color-coded based on the quality of the data
they are transmitting:
• Gray–Satellites have not been located but they are shown in the constellation because they appear in the PN-60's
almanac data.
• Red–The receiver is tracking the satellite, but it is not using it to navigate.
• Yellow–The receiver is tracking the satellite, predicted ephemeris data is available when a 3-D fix has not been
obtained, and the satellite is being used for navigation.
• Green–The receiver is tracking the satellite, ephemeris data is available, and the satellite is being used for
navigation.
• Blue–The receiver is tracking the satellite, ephemeris data is available, the satellite is being used for navigation, and
WAAS corrections are available.
GPS and WAAS Status
The Global Positioning System (GPS) is a system of satellites that orbit the earth to provide position and navigation
information. The Wide Area Augmentation System (WAAS) is system of satellites and ground stations that correct GPS
signals to improve accuracy.
The GPS status is based on the satellite acquisition status.
• GPS Off–The GPS receiver is turned off.
• No Fix–The GPS does not have sufficient satellite data to determine your current GPS position.
• 2-D–The GPS connection is successful, but the connection quality is not as good as a 3-D fix. Move your receiver
to another location to get better reception.
