NASAWASH
2-line Keplerian Elements File Clean-Up

Description

NASAWASH extracts valid 2-line Keplerian element sets from a text file, which may contain other text of various kinds.

NASAWASH is a command-line program that can be used standalone or as a filter.

System Requirements

To run the included executable, any environment capable of running well-behaved MS-DOS programs, including all versions of Windows, OS/2, and most DOS emulation environments.

The program should also be compilable on other command-line environments, such as Unix.

Features

Command-line program
Accepts Unix, MS-DOS, or Macintosh end-of-line terminators
Removes non-Keplerian text before, after, or between element sets
Removes line prefixes, such as email quoting characters
Removes line suffixes
Checks element set checksums
Generates compatible element set checksums (no "+" signs)
Runs as filter, or with specified input file, or with both input and output files specified

Limitations

Does not interpret Keplerian elements to check validity of data
Cannot fix corrupted element sets, such as those where runs of spaces have been replaced with single spaces
Because NASAWASH is designed to run as a filter, invoking it with no arguments (and no command-line redirection) causes it to just sit there and do nothing. This is a feature, trust me.

Current Status

Stable. No current development plans. The current released version of NASAWASH is 0.5, released May 21, 1995, but recompiled and re-released in March 2002.

History

May 1995 - Development started, released next day.
March 2002 - Rebuilt executable (DOS only this time) for distribution.

Known Bugs

None.

Distribution

NASAWASH may be distributed freely (unmodified) and may be used freely for non-commercial purposes only.
