Constellation Window: The Constellation window displays each satellite being tracked by the
receiver. When you select a satellite, the window shows details of its PRN, signal-to-noise ratio
(SNR), azimuth and elevation. Concentric circles from 0° to 90° represent elevations from the
horizon to directly overhead, respectively. The azimuth is mapped on a compass relative to true
north. The colored rings indicate the lowest elevation cut-off angles at which satellites are tracked
and can be changed or viewed with the
button.
Each satellite being tracked is represented with an icon according to its satellite system, as follows:
• Circular for GPS
• Square for GLONASS
• Hexagon for SBAS
There are also information icons and values at the bottom of the window:
• The number of GPS/GLONASS satellites used in the solution verses the number
being tracked. For example, 0/5 next to the Russian flag shows that the receiver is
tracking 5 GLONASS satellites but using none in the position solution
• The satellite PRN number, azimuth and elevation
• The signal-to-noise ratio (SNR) value and indicator
The PRN of the satellite is displayed on the icon and colours show the status of the satellite or the
tracking channel. Click a satellite to display its information.
When a valid position is achieved, dilution of precision (DOP) values can be viewed in the DOP
window.
To open the window, select Constellation Window from the View menu or by click the toolbar button.
•
Tracking Status Window: The Tracking Status window displays key information about each of
the receiver’s processing channels, including the PRN of the satellite being tracked on the
channel, the signal-to-noise ratio, pseudorange measurements, Doppler values, residuals
measurements and lock time from the satellite.
The TRACKSTAT log provides the data for many of the fields listed in this window. The number
of channels displayed depends on your model of receiver and the bars are color-keyed to show the
channel’s frequency type.
To open these windows, select Tracking Status Window GPS/GLONASS from
the View menu or click the American and Russian flag toolbar buttons.
