NAME
GPS::SpaceTrack - Package for calculating the position of GPS satellites
SYNOPSIS
use GPS::SpaceTrack; my $obj=GPS::SpaceTrack->new(filename=>"gps.tle"); print join("\t", qw{Count PRN ELEV Azim SNR USED}), "\n"; foreach ($obj->getsatellitelist({lat=>38.870997, lon=>-77.05596})) { print join("\t", $_->prn, $_->elev, $_->azim, $_->snr, $_->used), "\n"; }
DESCRIPTION
CONVENTIONS
Function naming convention is "format of the return" underscore "format of the parameters."
CONSTRUCTOR
new
The new() constructor passes paramaters to the filename() method.
my $obj = GPS::SpaceTrack->new(filename=>$filename);METHODS
getsatellitelist
The getsatellitelist() method returns a list of Net::GPSD::Satellite objects. The getsatellitelist() method is a wrapper around getsatellitelist_rad() for data formatted in degrees instead of radians.
my $list=$obj->getsatellitelist({lat=>$lat, lon=>$lon, alt=>$hae, time=>$time}); #degrees, degrees, meters, seconds from epoch
my @list=$obj->getsatellitelist({lat=>$lat, lon=>$lon, alt=>$hae, time=>$time}); #degrees, degrees, meters, seconds from epochgetsatellitelist_rad
The getsatellitelist_rad() method returns a list of Net::GPSD::Satellite objects. This method is basically a wrapper around Astro::Coord::ECI::TLE.
my $list=$obj->getsatellitelist_rad({lat=>$lat, lon=>$lon, alt=>$hae, time=>$time}); #radians, radians, meters, seconds from epoch
my @list=$obj->getsatellitelist_rad({lat=>$lat, lon=>$lon, alt=>$hae, time=>$time}); #radians, radians, meters, seconds from epochfilename
Method to get or set the filename of the TLE data.
my $filename=$obj->filename;
my $filename=$obj->filename(filename=>$filename);TODO
