NAME
seesat5 - provides satellite visibility information.
SYNOPSIS
seesat5 [ report ] [ go <Label> ] | [ <command> ... ]
DESCRIPTION
This program uses the sgp4 algorithm provided by NORAD to produce
position information on a satellite. Seesat5 can produce tracking
information for one satellite over a period of several days, or for a
collection of satellites over that period. By providing filter
conditions seesat5 prints out only those satellites you might have a
chance to see rather than all the satellites that pass above the
horizon.
Seesat5 is typically run by placing control commands into an init file
called SEESAT5.INI. See seesat5 (7) for the description of these
commands. If there is no init file Seesat5 will present the operator
with a ’>’ prompt where commands can be entered. From the prompt
seesat5 will begin analysis when sufficient parameters have been
entered to begin the run.
Seesat5 uses selection conditions to filter the data so that only high
and bright satellites are printed. Note that the selection conditions
are used to select whether or not the current passes data will be
printed. If it is printed, then the complete pass data is printed. ie.
all data from when the satellite comes over the horizon until it goes
below.
For lines that satisfied ALL the selection conditions, a "+" sign is
printed as the first character.
Options
report This option will disable printing of report records in the
output of the run. These include all command lines found in
SEESAT5.INI or entered from the command line or the prompt.
go Followed by a label, this option causes branching within the
SEESAT5.INI to begin execution at the line following label.
Branching occurs when the cmdline command is executed in the
SEESAT5.INI file.
command
Most of the commands that can be found in SEESAT5.INI can be
entered on the command line. If you desire the SEESAT5.INI file
to execute after the command line be sure to make the last
command RET.
FILES

BUGS
Seesat5 is not always able to check data integrity. Since computation
and output is driven by the data in the two line element, subtle errors
in a tle can cause floating point exceptions. In addition there are
several commands that do not work well together, like SHOWTLE and
RUNTIME. Please report any problems with seesat5 to Dale Scheetz
