libSATCAT

C Parser for the SATCAT Format.

ANSI C compliant and linkable with C++.

• SATCAT Data: https://www.celestrak.org/pub/satcat.txt

Build

The demo program test/test.c can be compiled as follows:

cd test
gcc ../src/satcat.c ../src/satcat_code.c test.c -lm -ansi -I../src -o bin
./bin

Yielding the following output:

Parsed and Validated 52802 satellites in 0.066405s.
Found 51898 valid satellites and 904 invalid satellites.

First satellite:
Name: SL-1 R/B
Catalog Number: 1
Status: Decayed
Source: Commonwealth of Independent States (former USSR)
Launch Site: Tyuratam Missile and Space Center, Kazakhstan

Usage

By default, strings within struct SatCat are NOT NULL-terminated, and are right-padded with spaces. To enable NULL-terminated strings, define SC_CSTRING.

The SATCAT library consists of the following files:

satcat.c + satcat.h

Parses and validates SATCAT strings.

• sc_parse: Parses a SATCAT-formatted string into a struct SatCat
• sc_validate: Validates if string is SATCAT-formatted

satcat_code.c + satcat_code.h [Optional]

Provides description strings for SATCAT Operational Status, Source, and Launch Site Codes.

• SC_STR5_TO_CODE macro: converts a 5-character code (either char source[5] or char launch_site[5] in struct SatCat) into a numeric contant of type sc_code_t, equal to one of SCSRC_* or SCSITE_*
• sc_source_str & sc_launch_site_str: takes a sc_code_t code and return a verbose description of the satellite's source or launch site.
• sc_status_str: takes an Operational Status Code (char opstat in struct SatCat, or SCSTAT_*), and returns a description of the satellite's status.

These files can be regenerated using util/gen_code.py if the SATCAT Operational Status, Source, and Launch Site Codes are expanded.
