Function Documentation

def orbito.module_orbito.close_orbito

(

)

Unload spice meta kernels.

def orbito.module_orbito.find_perihelion	(		scraft,
			date_begin,
			date_end,
			write = False
	)

Return list of all perihelion of a scraft between 2 dates.

Parameters

[out]	Times_perihelion,:	datetimes of the perihelion. List of module_timespace.Time objects
[out]	Positions_perihelion,:	positions of the perihelion. List of module_timespace.Coordinate objects.

Here is the call graph for this function:

def orbito.module_orbito.frame_transfo	(		points_in,
			frame_in,
			frame_out,
			times
	)

Frame transformation for a coordinate object.

Parameters

[in]	points_in,:	list of module_timespace.Coordinate object with x,y,z attributes filled.
[in]	frame_in,frame_out,:	one of Spice reference frame. IAU_SUN, GSE, HEE...
[in]	times,:	list of module_timespace.Time objects
[out]	points_out,:	list of module_timespace.Coordinate in frame_out referential.

def orbito.module_orbito.frame_transfo_velocity	(		velocities_in,
			frame_in,
			frame_out,
			times
	)

Velocity frame transformation for a coordinate object.

Parameters

[in]	velocities_in,:	list of module_timespace.Coordinate object with x,y,z attributes filled.
[in]	frame_in,frame_out,:	one of Spice reference frame. IAU_SUN, GSE, HEE...
[in]	times,:	list of module_timespace.Time objects
[out]	velocities_out,:	list of module_timespace.Coordinate in frame_out referential with only x,y,z filled.

def orbito.module_orbito.init_orbito

(

)

Load general spice files (naifXXXX.tls,pckXXXXX.tpc).

Here is the caller graph for this function:

def orbito.module_orbito.load_orbito

(

scraft

)

Load in memory specific spice files need for the spacecraft.

General spice files must be loaded before (naifXXXX.tls,pckXXXXX.tpc).

Todo:

Check if init_orbito was called before.

Here is the caller graph for this function:

def orbito.module_orbito.read_orbito	(		scraft,
			times,
			referential,
			correction,
			observer
	)

For given Time object list, return sc position as a Coordinate list.

Use Spice spkezr to get S/planet position in some referential and with some correction.
Referential:

• IAU_SUN: equivalent to HelioGraphic Coordinates.

Correction:

• None: Uncorrected data.
• LS+S: Light time and stellar aberration correction.

For the moment, SOLO is shifted with 10 years.

(

scraft

)

Rename into SPICE names:

• STA into STEREO AHEAD
• STB into STEREO BEHIND
• PSP into SPP
• SOLO into SOLO
• BEPI into BepiColombo
