Orbits
  
   _Need a general entry here!_
   
    Where can I learn about satellite orbits?
    
   Wim Bakker has compiled a list of online references at
   http://www.itc.nl/~bakker/orbit.html.
   
   Wim adds the question _"When can *I* see a specific satellite"_, and
   suggests the following pointers from his list:
     * Visual Satellite Observer's Home Page:
       http://www.rzg.mpg.de/~bdp/vsohp/satintro.html
     * Satellite Observing Resources:
       http://www-leland.stanford.edu/~iburrell/sat/sattrack.html
       
    Satellite Orbital Elements
    
   _Thanks to Peter Bolton (pbolton@clyde.pc.my) for this one!_
   
   Jonathan's Space Report is at
   http://hea-www.harvard.edu/QEDT/jcm/jsr.html. The introduction:
   
   The Space Report ("JSR") is issued about once a week. It describes all
   space launches, including both piloted missions and automated
   satellites. Back issues are available by FTP from sao-ftp.harvard.edu
   in directory pub/jcm/space/news. To receive the JSR each week by
   direct email, send a message to the editor, Jonathan McDowell, at
   jcm@urania.harvard.edu. Feel free to reproduce the JSR as long as
   you're not doing it for profit. If you are doing so regularly, please
   inform Jonathan by email. Comments, suggestions, and corrections are
   encouraged.
   
    How do I convert Landsat Path/Row to Lat/Long?
    
   In response to this question, Wim Bakker wrote:
The SATCOV program is available by anonymous FTP from sun_01.itc.nl
(192.87.16.8). Here's how to get it:

$ ftp 192.87.16.8
Name: ftp
Password: your-email-address
ftp> bin
ftp> idle 7200
ftp> prompt
ftp> cd /pub/satcov
ftp> mget *
ftp> bye
$

If you can't use FTP, drop me a line and I will send a uuencoded version
by email.

Those of you who prefer a WWW interface can obtain it from the following URL:
        http://www.itc.nl/~bakker/satcov
Don't forget to set the "Load to local disk" option.

SATCOV is a PC program for converting Path/Row numbers of Landsat and
K/J of SPOT to Lat/Lon and vice versa. Furthermore it can predict the orbits
of the NOAA satellites, although I wouldn't recommend it for this purpose!
But that's an other can of worms....
