- NASAPREP.EXE - Prepares the NASADATA.ORB file for use with NASAORB
-
- Background - The SATEQ program needs to be loaded with data for each
- satellite. This data is distributed by NASA in a standardized format,
- which SATEQ cannot read, so to save the effort and errors involved in
- entering the data by hand, the conversion program NASAORB was created.
- However, this program required the user to pre-edit the NASA data
- file, again required effort and possible errors by the user. NASAPREP
- is a preprocessor for NASAORB.
-
- NASAORB expects to read a file called NASADATA.ORB, and produce a file
- called SATKEPN.DAT, which is loaded by SATEQ. Therefore, NASAPREP
- will output a file by this name. NASAPREP uses a config file call
- SATNAMES.ORB that you create. This file is a list of the birds you
- want out of NASADATA.ORB file. The SATNAMES.ORB file also lets you
- rename the bird, as names like 1990 005H are hard to use. Here is a
- sample SATNAMES.ORB file:
-
- "OSCAR 10" "OSCAR10"
- "RS-10/11"
- "AO-13" "OSCAR13"
- "Mir"
- "GOES 2" "GOES2"
-
- The first name is the name exactly as it appears in the NASADATA.ORB
- file. The second name is the alias that you want it renamed to.
-
- What NASAPREP will do:
-
- 1. Check NASADATA.ORB to see if it NASAPREP has ever been run before.
- If it is the first time, it will copy it to NASADATA.SAV.
-
- 2. It will read SATNAMES.ORB to load up your list of names and
- aliases.
-
- 3. Read NASADATA.SAV and output the selected ones to a newly created
- NASADATA.ORB file.
-
- 4. Run NASAORB to process the newly created and edited NASADATA.ORB
- file which will create the data file for SATEQ.
-
- Messages will appear on the screen to tell what's being done. A list
- of any birds that were in the satnames file but were not found in the
- NASADATA will also be displayed. You can save the messages in a file
- if you need to read them all by redirecting the stdout to a file.
- e.g. NASAPREP >msgfilename
