Constructor Detail

ObservableSatellite

public ObservableSatellite(int propagatorIndex)

Simple constructor.

This constructor builds a default name based on the propagator index.

Parameters:

propagatorIndex - index of the propagator related to this satellite

ObservableSatellite

public ObservableSatellite(int propagatorIndex,
                           String name)

Simple constructor.

Parameters:

propagatorIndex - index of the propagator related to this satellite

name - satellite name (if null, a default name built from index will be used)

Since:

13.0

Method Detail

getName

public String getName()

Build a name for the satellite.

This is mainly useful to build the arguments for AmbiguityCache.getAmbiguity(String, String, double)

Returns:

name for the satellite

Since:

12.1

getPropagatorIndex

public int getPropagatorIndex()

Get the index of the propagator related to this satellite.

Returns:

index of the propagator related to this satellite

getClockOffsetDriver

public ParameterDriver getClockOffsetDriver()

Get the clock offset parameter driver.

The offset value is defined as the value in seconds that must be subtracted from the satellite clock reading of time to compute the real physical date. The offset is therefore negative if the satellite clock is slow and positive if it is fast.

Returns:

clock offset parameter driver

getClockDriftDriver

public ParameterDriver getClockDriftDriver()

Get the clock drift parameter driver.

The drift is negative if the satellite clock is slowing down and positive if it is speeding up.

Returns:

clock drift parameter driver

Since:

10.3

getClockAccelerationDriver

public ParameterDriver getClockAccelerationDriver()

Get the clock acceleration parameter driver.

Returns:

clock acceleration parameter driver

Since:

12.1

getQuadraticClockModel

public QuadraticClockModel getQuadraticClockModel()

Get a quadratic clock model valid at some date.

Returns:

quadratic clock model

Since:

12.1

equals

public boolean equals(Object other)

Overrides:

equals in class Object

Since:

12.0

hashCode

public int hashCode()

Overrides:

hashCode in class Object

Since:

12.0
