Satellites

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

Status:

 

Parameter

Designation

$PASHQ

GPS

Indicates that the receiver has the GPS recep­tion capability (always On).

-

GLONASS

Indicates whether the receiver has the GLO­NASS reception capability (On) or not (Off).

GLO

SBAS

Indicates whether the receiver has the SBAS re­ception capability (On) or not (Off).

SBA

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.

PEM

 

For each visible satellite of each constellation received (GPS, GLONASS and SBAS):

 

Parameter

Designation

$PASHQ

ID

Satellite ID number.

SAT

Status

Gives status information for each satellite:

   Used: Satellite received and used

   Blank: Satellite received but not used

   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) and LP2(Y) signals (GPS)

- For L1C and L2C signals (GLONASS)

- For L1C signal (SBAS)

SAT

Smooth Count (s)

Smooth counts, in seconds:

- For L1C, L1P(Y) and LP2(Y) signals (GPS)

- For L1C and L2C signals (GLONASS)

- For L1C signal (SBAS).

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 three 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)

   Blue: SBAS (dark blue: satellite used; purple: satellite not used)
