[aprssig] FW: AO51/GO32 Mobile Manual Tracking Table updated

[Robert Bruninga]

Lonely on the open APRS road?  Tune in the mobile satellites...

The AO51 mobile tracking table only has 5 entries because the
pass times repeat every 5 days so it can be reduced to a single
table good for 2 months like this:

EASTERN Daylight Time AO-51
01Aug 07Aug 13Aug 19Aug 25Aug
----- ----- ----- ----- ----- 
0800  0855  0815  0740  0835  
0935              0920

1910  2010  1930  1850  1950  
                  2030  

Cut/paste on your dashboard or shack bench.  The table is good
for a month or two and allows you to always estimate satellite
passes within 5 minutes.  You don't need no stinking PC for 2
months.  These are the peak passes for your time zone.  If one
peak pass is shown, then there are two other lower passes 100
minutes earlier and later.  If two modest passes are shown, then
the others will probably be too low.

TO use this on any day, just find the column nearest todays date
and count forward or backward the number of days.  SO for today
(July 29th), start on 1 Aug and count (rotate) to the left 3
days.  So tonight's pass will be at 1930 (and one at 1750 and
2110 ish)

I updated the tables for both birds and each USA time zone on my
Mobile Manual Tracking web page:

There are other hints there that allow you to be more accurate
based on where you live in your time zone, etc.  The table for
the GO32 APRS satellite repeats every 9 days and is good for 3
months or so:

EASTERN Daylight Time
01Aug 11Aug 21Aug 31Aug 10Sep 20Sep 30Sep 10Oct 20Oct
----- ----- ----- ----- ----- ----- ----- ----- -----
0920  0855  0835  0810  0930  0905  0845  0820  0940
            1015  0950              1025  1000

2035  2015  1955  1930  2005  2025  2005  1940  1920
            2135  2110                    2120  2100

If you get bored on your daily commute and want to see what the
satellites are doing and you are on the road during these times,
you don't need a PC.  Just look at your dashboard, do a little
mental processing, and bingo, you can estimate the next pass
easily.
