new_pole

Description

This program solves for a user input old and new right ascension (RA), declination (DEC), prime meridian (PM), and rotation rate (OMEGA), and updates the landmark center locations and map frames, and the spacecraft position, camera unit vectors and Sun unit vectors in all relevant files.

Input Files

INIT_LITHOS.TXT - Initialization file which contains the parameter PCK, which defines the planetary constants for a variety of objects (such as Bennu or the Sun). This is required for SPICE function calls.
DATA/ - Directory containing SPICE kernels.
LMRKLIST.TXT - list of landmarks.
PICTLIST.TXT - list of pictures.
SUMFILES/ - Directory containing picture .SUM files.

$/!\$ INIT_LITHOS.TXT, DATA/, and LMRKLIST.TXT must be in the working directory.

$/!\$ unlike pole, new_pole does not require POLE.TXT. Instead the user inputs the pole RA, Dec, PM, OEMGA, via standard input.

Using new_pole

Input the old right ascension (deg), declination (deg), prime meridian (deg), and rate of rotation (deg/day).

 enter old RA, DEC, PM, OMEGA
86   -65   89.00000000   2010.48945

Input the new right ascension (deg), declination (deg), prime meridian (deg), and rate of rotation (deg/day).

 enter new RA, DEC, PM, OMEGA
86.60062   -65.00002    90.42707  2009.99979311

Input a time in UTC.
$/!\$ Make sure the time is within the span supported by the kernels.

 Input epoch UTC0

new_pole:

Updates the landmark center location (VLM), and map frame (UX, UY, and UZ) in the LMK files;
Updates the .MAP files;
Updates the spacecraft position (SCOBJ), camera unit vectors (CX, CY, and CZ), and Sun unit vector (SZ) in the SUMFILES;
Updates the spacecraft position (SCOBJ), camera unit vectors (CX, CY, and CZ), and Sun unit vector (SZ) in the NOMINALS.
Outputs the commands required to run GEOMETRY.

Here is a sample output GEOMTERY commands:

new_pole generates a POLE.TXT file in which it records the new RA, DEC, PM, and OMEGA.

Here is a sample POLE.TXT:
