Accessory Test lists the accessories connected to the system.
GPS DIAGNOSTIC VIEW
GPS Diagnostic View, which is only available when a GPS Receiver is attached to you
900 Series, shows a sky chart and numerical data from the GPS receiver. The sky chart
shows the location of each visible GPS satellite with its satellite number and a signal
strength bar. A dark grey bar indicates that the satellite is being used to determine your
current position. A light gray bar indicates that the satellite is being monitored, but is
not yet being used.
This view also reports the current position, local time and date, and other numeric
information. The current GPS Fix Type is reported as No Fix, 2D Fix, 3D Fix, or Enhanced.
An Enhanced fix has been augmented using information from WAAS, EGNOS, or MSAS.
A 3D or Enhanced Fix is required for navigation. HDOP (the Horizontal Dilution of
Precision) is a GPS system parameter which depends on the current satellite
configuration. HDOP is used to calculate the Estimated Position Error.
