Satellites
The Satellites page details the data received from the different constellations. The information provided is split into six tabs: Status, GPS, GLONASS, GALILEO, SBAS, QZSS and Polar View.
Status:

---|---|---|
GPS |
Indicates whether the receiver has the GPS reception capability (On) or not (Off). |
GPS |
GLONASS |
Indicates whether the receiver has the GLONASS reception capability (On) or not (Off). |
GLO |
GALILEO |
Indicates whether the receiver has the GALILEO reception capability (On) or not (Off). |
GAL |
SBAS |
Indicates whether the receiver has the SBAS reception capability (On) or not (Off). |
SBA |
QZSS |
Indicates whether the receiver has the QZSS reception capability (On) or not (Off) |
QZS |
Recording and Output Elevation Mask |
Gives the current value of elevation angle used in the data recording and output process. |
ELM |
Position Elevation Mask |
Gives the current value of elevation angle used in the position computation process. |

Satellite ID number. |
SAT |
Status |
Gives status information for each satellite: • Used: Satellite received and used. You may read “Used - SBAScorr”, “Used - DGPScorr”, “Used - L1RTKcorr” or “Used - L1L2RTKcorr” depending on which type of corrections are available for the satellite. • Tracked: Satellite received but not used. • Blank: Satellite in view. • No ephemeris: Satellite does not provide ephemeris data. • Unhealthy: Satellite declared unhealthy. • Bad URA: Bad user range accuracy. |
SAT |
Azimuth |
Azimuth angle, in degrees, of the satellite. |
SAT |
Elevation |
Elevation angle, in degrees, of the satellite. |
SAT |
SNR (dB.Hz) |
Signal-noise ratios, in dB.Hz: - For L1C, L1P(Y), L2CS, LP2(Y) and L5 signals (GPS) - For L1C and L2C signals (GLONASS) - For E1 and E5a signals (GALILEO) - For L1C signal (SBAS) - For L1C, L2CS and L5 (QZSS) |
SAT |
Smooth Count (s) |
Smooth counts, in seconds: - For L1C, L1P(Y), L2CS, LP2(Y) and L5 signals (GPS) - For L1C and L2C signals (GLONASS) - For E1 and E5a signals (GALILEO) - For L1C signal (SBAS). - For L1C, L2CS and L5 (QZSS) Smooth count refers to that period of time during which the signal phase is tracked smoothly without disruption (no cycle slip). |

The Polar View shows the location in the sky of each of the visible satellites from the four different constellations. Different colors are used to display the numbers of the visible satellites:
• Green: GPS (dark green; satellite used; pale green: satellite not used)
• Red: GLONASS (dark red: satellite used; pale red: satellite not used)
• Orange: GALILEO (dark orange: satellite used; pale orange: satellite not used)
• Blue: SBAS (dark blue: satellite used; purple: satellite not used)
• Dark blue: QZSS (ink blue: satellite used; pale blue: satellite not used)
• For all constellations, the numbers of the satellites that are visible but not tracked are framed in dotted line.
