Field Details

DEFAULT_ELEVATION_SWITCH_INF

public static final double DEFAULT_ELEVATION_SWITCH_INF

Default elevation above which interval should be switched to fine interval (-5°).

Since:

13.0

DEFAULT_ELEVATION_SWITCH_SUP

Method Details

getAdaptableInterval

public static AdaptableInterval getAdaptableInterval(TopocentricFrame topo,
 double elevationSwitchInf,
 double elevationSwitchSup,
 double fineCheckInterval)

Method providing a candidate AdaptableInterval for arbitrary elevation detection with forward propagation. It uses a Keplerian, eccentric approximation.

Parameters:

topo - topocentric frame centered at ground interest point

elevationSwitchInf - elevation above which interval will switch to fineCheckInterval (typically DEFAULT_ELEVATION_SWITCH_INF which is -5°)

elevationSwitchSup - elevation below which interval will switch to fineCheckInterval (typically DEFAULT_ELEVATION_SWITCH_SUP which is +15°)

fineCheckInterval - check interval to use when elevation is between elevationSwitchInf and elevationSwitchSup

Returns:

adaptable interval for detection of elevation with respect to topo

Since:

13.0
