GPS::OID(3) User Contributed Perl Documentation GPS::OID(3)NAMEGPS::OID - Package for GPS PRN - Object ID conversions.
SYNOPSIS
use GPS::OID;
my $obj = GPS::OID->new();
print "PRN: ", $obj->prn_oid(22231), "\n";
print "OID: ", $obj->oid_prn(1), "\n";
DESCRIPTION
This module maps GPS PRN number to Satellite OID and vice versa.
Object Identification Number (OID)
The catalog number assigned to the object by the US Air Force. The
numbers are assigned sequentially as objects are cataloged. This is the
most common way to search for TLE data on this site.
Object numbers less then 10000 are always aligned to the right, and
padded with zeros or spaces to the left.
Pseudo Random Numbers (PRNs)
GPS satellites are identified by the receiver by means of PRN-numbers.
Real GPS satellites are numbered from 1 - 32. WAAS/EGNOS satellites and
other pseudolites are assigned higher numbers. The PRN-numbers of the
satellites appear on the satellite view screens of many GPS receivers.
CONVENTIONS
Function naming convention is "format of the return" underscore "format
of the parameters."
