file. These are all roughly the same altitude and 6 degrees inclination. One<br>
is out in front of the others significantly. Probably pretty easy to look at<br>
the RCS and figure which is LAPAN-A2, as it is fairly big compared to the<br>
other secondary payloads.<br>
<br>
<br>
<br>
For my location at ~28.3N, I see about 5 passes a day, clumped together in a<br>
row, with max elevations of 3-4 degrees, and max length of ~7-8 minutes. I<br>
think if you are north of 30 degrees, you will be out of luck on this one.<br>
<br>
<br>
<br>
When the APRS digi is activated, I will plan on a gateway with a good<br>
performing low elevation antenna. This could become an important resource to<br>
boaters and such in the Caribbean, especially with the high revisit rate. It<br>
will be quite the boon for the low latitude ops who don't get the same<br>
number and quality of passes from polar orbiters as those north of the<br>
tropics!<br>
