Figure 53: Channel Status Screen
The data below is displayed for each channel on the GPS, GLONASS, and SBAS
windows. Differences between the constellations are identified.
 PRN: The satellite number assigned to each channel.
 GPS: The valid range is 1-32. (The receiver allocates the range of 1-37, with 33-37
reserved for expansion.)
 GLONASS: The valid range is 1-24.
 SBAS: The valid range is 120-138.
 AZ: Azimuth. The horizontal angle of the satellite relative to the receiver position in
reference to North ranging from 0 (360) to 359 degrees.+
 EL: Elevation. The vertical angle of the satellite off the horizon ranging from 0 degrees
to a zenith of 90 degrees.
 CH (Code Type): The channel number of the receiver, within a range of 0 – 53. The
code types tracked by the channel are:

GPS: L1CA, L1P1, L2, L2C, and L5 based on the [TRACKINGMODE]
command settings

GLONASS: G1C, G2C, G1P, and G2P based on the [TRACKINGMODE]
command settings

SBAS : L1CA (These code types are displayed, but don’t apply: L1P1, L2,
L2C, and L5.)
 ST: Status. The channel tracking status of each channel. The status code LOCK
means the channel is locked up for measurement type and satellite, measurements
are ready.
 C/No: Signal-to-Noise. The signal-to-noise value varies depending on satellite
elevation and any obstructions between the satellites and the receiver. The typical
