Inherited methods

From class


  
    java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long millis, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long millis)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

Public methods

getAzimuthDegrees

Added in API level 24

float getAzimuthDegrees (int satIndex)

Retrieves the azimuth the satellite at the specified index.

Parameters
`satIndex`	`int`: the index of the satellite in the list.

Returns
`float`

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.

Parameters
`satIndex`	`int`: the index of the satellite in the list.

Returns
`float`

getConstellationType

Added in API level 24

int getConstellationType (int satIndex)

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

Parameters
`satIndex`	`int`: the index of the satellite in the list.

Returns
`int`

getElevationDegrees

Added in API level 24

float getElevationDegrees (int satIndex)

Retrieves the elevation of the satellite at the specified index.

Parameters
`satIndex`	`int`: the index of the satellite in the list.

Returns
`float`

getSatelliteCount

Added in API level 24

int getSatelliteCount ()

Gets the total number of satellites in satellite list.

Returns
`int`

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
