[aprssig] New APRS satellite: LAPAN-A2

Chuckle...  To see where it lands (no pun intended) I Googled "30 degrees north latitude" and Google maps gives me Gideon Welles Craft Beer Bar & Kitchen in Chicago....

 This
 is just one of several new Chinese Ham sats and many of them
 have low inclination orbits.  Meaning if you live near the
 equator you get a pass every 90 minutes ALL DAY AND NIGHT
 LONG.

 This should make APRS ideal for sailors and boaters. 
 These satelltes also have FM voice and so it should be fun
 in the carribean   You cant see them north of about 30
 degrees latitude.

 It also suggests we need to make sure we ahve
 plenty of IGates round the world near the equator.

 I see Celestrak now has objects 2015-052A, B, C, D, and H in
 the tle-new.txt

 file. These are all roughly the same altitude and 6 degrees
 inclination. One

 is out in front of the others significantly. Probably pretty
 easy to look at

 the RCS and figure which is LAPAN-A2, as it is fairly big
 compared to the

 other secondary payloads.

 For my location at ~28.3N, I see about 5 passes a day,
 clumped together in a

 row, with max elevations of 3-4 degrees, and max length of
 ~7-8 minutes. I

 think if you are north of 30 degrees, you will be out of
 luck on this one.

 When the APRS digi is activated, I will plan on a gateway
 with a good

 performing low elevation antenna. This could become an
 important resource to

 boaters and such in the Caribbean, especially with the high
 revisit rate. It

 will be quite the boon for the low latitude ops who
 don't get the same

 number and quality of passes from polar orbiters as those
 north of the

 tropics!
