This read-only value reports the azimuth, or compass bearing, of a specific satellite (identified by PRN) as seen from the device's GPS antenna. Admins use it together with elevation to understand the sky distribution of satellites the receiver can see, which helps when troubleshooting a poor fix caused by an obstructed antenna site. For example, several satellites clustered at azimuths pointing toward a known building or hillside near the antenna would suggest that obstruction is degrading GPS reception from that direction.
