Then you are to be congratulated. There are still RELAY/WIDE
stations running around, granted that not many of them are IGates.<br>
<br>
But the point of my effort is to get information available to APRS
users without needing to mobilize the 2,504 IGate operators
world-wide to get something going.<br>

Sure, it would have to be restarted to add a new satellite, but I've not done that since it was installed.

I'm trying to offer a globally-accessible satellite information service. I'm not trying to replace what DIGI_NED has accomplished at the local level, but provide something new and functional from a much broader perspective and service area. And without QRMing the local RF channel when no-one is listening.
There is no way in APRS for a central server to push information out to a local RF APRS network except by sending an APRS message directed to a station that was recently heard local to an IGate. And the only way to reliably know that is to design and implement a centralized query / response system.

<pre wrap="">I have to come back to the DIGI_NED model. One packet per bird every
10 minutes with the next predicted AOS (or something) time. Then when
it's in range, one packet a minute with current information.
It's surprising how one finds the time to bounce a few packets through
a bird or listen to the channel when it just happens to be opportune.
DIGI_NED has the poll feature. Used it once to verify it works and
never went back.
