Constellation type constant for Beidou.

Constant Value: 5 (0x00000005)

CONSTELLATION_GALILEO

added in API level 24

Public methods

getAzimuthDegrees

added in API level 24

float getAzimuthDegrees (int satIndex)

Retrieves the azimuth the satellite at the specified index.

getCarrierFrequencyHz

added in API level 26

float getCarrierFrequencyHz (int satIndex)

Gets the carrier frequency of the signal tracked.

For example it can be the GPS central frequency for L1 = 1575.45 MHz, or L2 = 1227.60 MHz, L5 = 1176.45 MHz, varying GLO channels, etc. If the field is not set, it is the primary common use central frequency, e.g. L1 = 1575.45 MHz for GPS. For an L1, L5 receiver tracking a satellite on L1 and L5 at the same time, two measurements will be reported for this same satellite, in one all the values related to L1 will be filled, and in the other all of the values related to L5 will be filled.

The value is only available if hasCarrierFrequencyHz(int) is true.

getCn0DbHz

added in API level 24

float getCn0DbHz (int satIndex)

Retrieves the carrier-to-noise density at the antenna of the satellite at the specified index in dB-Hz.

getConstellationType

added in API level 24

int getConstellationType (int satIndex)

Retrieves the constellation type of the satellite at the specified index.

getElevationDegrees

added in API level 24

float getElevationDegrees (int satIndex)

Retrieves the elevation of the satellite at the specified index.

getSatelliteCount

added in API level 24

int getSatelliteCount ()

Gets the total number of satellites in satellite list.

getSvid

added in API level 24

int getSvid (int satIndex)

Gets the identification number for the satellite at the specific index.

This svid is pseudo-random number for most constellations. It is FCN & OSN number for Glonass.

The distinction is made by looking at constellation field getConstellationType(int) Expected values are in the range of:

• GPS: 1-32

• SBAS: 120-151, 183-192

• GLONASS: One of: OSN, or FCN+100

• 1-24 as the orbital slot number (OSN) (preferred, if known)

• 93-106 as the frequency channel number (FCN) (-7 to +6) plus 100. i.e. encode FCN of -7 as 93, 0 as 100, and +6 as 106

• QZSS: 193-200

• Galileo: 1-36

• Beidou: 1-37

hasAlmanacData

added in API level 24

boolean hasAlmanacData (int satIndex)

Reports whether the satellite at the specified index has almanac data.

hasCarrierFrequencyHz

added in API level 26

boolean hasCarrierFrequencyHz (int satIndex)

Reports whether getCarrierFrequencyHz(int) is available (i.e. carrier frequency is available for the satellite at the specified index).

hasEphemerisData

added in API level 24

boolean hasEphemerisData (int satIndex)

Reports whether the satellite at the specified index has ephemeris data.

usedInFix

added in API level 24

boolean usedInFix (int satIndex)

Reports whether the satellite at the specified index was used in the calculation of the most recent position fix.
