GPS Info
This GPS Info utility allows you to see information in regards to which GPS satellites
are accessible to your ike.
This information is available from the three options on the View menu.

Skyplot

Satellite Information (Sat info)

Navigation Info (Nav info)
Skyplot
This is the default screen in GPSInfo. (If you have moved
away from it, you can return by selecting
View > Skyplot .) It
shows a map of all the satellites that your ike is aware of, with
identification numbers. Solid circles mean that ike has an
active connection with the satellite.
This screen also gives information on the physical location of
your ike, based on data it receives from the GPS satellites.
The top of the screen is always North
Latitude and Longitude are the users geospatial
coordinates.
Altitude is the height above sea level in meters.
PDOP is a measure of the positional accuracy of the GPS
reading.
Nav Mode is the navigational status of GPS Fix. A 2-D (two
dimensional) fix only includes latitude and longitude data. A
3-D (three dimensional) fix also includes altitude data. The
available constellation of satellites available affects whether
altitude can be calculated.
Sat Info
This screen gives a table of all visible satellites, along with
numeric data about their location and accessibility. To access
this screen, select
View > SatInfo .
Fix is a column showing which satellites are being used to
calculate the GPS position.
SV provides the Space Vehicle (or GPS satellite)
identification number.
El gives the elevation of the satellite in degrees.
Az gives the azimuth of the satellite, with true north defined
as 0° and true south defined as 180°.
SNR gives the Signal-to-Noise Ratio of communication with
the satellite. A value between 40 and 50 is considered good.
