SLA-02
Programs


PC program :

VEC2TLE.EXE

Description:

PC program converts state vectors to 3-line elements

Known user : David Rabine


PC program :

TRAKSTAR.EXE

Description:

PC program - Given 3-line element file and date information, produces a shuttle location and elevation text file. Use 10 second increments for general location file. Use 1 second increments for merging with SLA-02 data. Time is in GMT. (GMT = local time + 5 hours)

Known user : David Rabine


IDL program :

trak2met2.pro

Author: Jim Roark

Location: avalon:/boxhill/roark/sla02

Description:

Converts a TRAKSTAR output file GMT to MET and adds a name (day/hour:min) variable. Saves a structure and name as an IDL "save" file. Output is used for location plotting based on MET. Default output file is 'trak_sla02.sav'.

Usage:

IDL> trak2met2, 'TRAKSTAR_file'

Example usage:

IDL> trak2met2, 'sts85.txt3'

Program will prompt for GMT launch time information and output file name.

Output: An IDL 'save' file

IDL program :

met_loc_all.pro

Author: Jim Roark

Location: avalon:/boxhill/roark/sla02

Description:

Reads the resulting output of 'trak2met2.pro' and a table of obsevation period times (observation_times_met3.txt) to produce individual B/W plots showing coverage for each observation period.

Usage:

IDL>met_loc_all, 'trak2met2_output_file'

Example Usage:

IDL>met_loc_all, 'trak_sla02.sav'

Output: Multiple Obs#X.ps files (where X = observation period number)

Known user: Jim Roark


IDL program :

global_loc.pro

Author: Jim Roark

Location: avalon:/boxhill/roark/sla02

Description:

Reads the resulting output of 'trak2met2.pro' and a table of obsevation period times (observation_times_met3.txt) to produce a color shadded relief map showing total mission coverage.

Usage:

IDL>global_loc, 'trak2met2_output_file'

Example Usage:

IDL>global_loc, 'trak_sla02.sav'

Notes:

1. Program will prompt for number of observation periods.
2. You need to enter the correct start and stop times in 'observation_times_met3.txt'

Output: idl.ps

IDL program :

global_loc2.pro

Author: Jim Roark

Location: avalon:/boxhill/roark/sla02

Description:

Reads the resulting output of 'trak2met2.pro' and a table of obsevation period times (observation_times_met3.txt) to produce a gray shadded relief map showing locations for each observation period in different colors.

Usage:

IDL>globasl_loc2, 'trak2met2_output_file'

Example Usage:

IDL>global_loc2, 'trak_sla02.sav'

Notes:

1. Program will prompt for number of observation periods.
2. You need to enter the correct start and stop times in 'observation_times_met3.txt'

Output: idl.ps

IDL program :

region_loc_c.pro

Author: Jim Roark

Location: avalon:/boxhill/roark/sla02

Description:

Reads the resulting output of 'trak2met2.pro' and a table of obsevation period times (observation_times_met3.txt) to produce a gray shadded relief map of a specified region showing locations for each observation period in different colors.

Usage:

IDL>region_loc_c, 'trak2met2_output_file'

Example Usage:

IDL>region_loc_c, 'trak_sla02.sav'

Notes:

1. Program will prompt for number of observation periods.
2. You need to enter the correct start and stop times in 'observation_times_met3.txt'

Output: idl.ps
