[aprssig] where is PSAT

“o/” is just another filter prefix. It denotes, “object type” (followed by call sign(s)) aprs-is filter
All filter prefixes need a space separation btwn them.

“d/” is for “digipeated by” (list of call signs, wild char)
“b/” is for “buddi list”
“o/” is for “object type”
And so on
(attached is a list of APRS-IS filter doc)

In a typical aprs-is filtering system, if one is looking for showing list of packets digipeated by “RS0ISS” or “PSAT” or “PCSAT”, a “d/RS0ISS*/PSAT*/PCSAT*” filter should be plenty good.

IMHO

The o is a whole new term.  It would be like:

b/RS0ISS*/W3ADO-1/ARISS d/RS0ISS*/W3ADO-1/ARISS o/PSAT*/

That's a space between ARISS and o/ just like there is between ARISS and d/

So if I have this already (http://aprsisce.wikidot.com/doc:satelliteops):
b/RS0ISS*/W3ADO-1/ARISS d/RS0ISS*/W3ADO-1/ARISS

Would I forward slash-separate this new section with an "o" sitting out there between slashes?  Like this?
b/RS0ISS*/W3ADO-1/ARISS d/RS0ISS*/W3ADO-1/ARISS/o/PSAT*/

Since they both share the ARISS alias, is it not going to be possible to do a constellation hop from the ISS to/from PSAT?  That sort of space-to-space APRS path is on my bucket list.  Along the same lines, if both are above me, and share the same alias, will I get two birds for one stone if I TX?  (Bad pun, running for cover.)

I updated my SATSRV with this TLE which is 4 days newer than what I had been running.

I've also started injecting a multi-line object "PSAT" into the APRS-IS similar to the "ISS" object that has been flying for over a year now.  If you've got an APRS-IS client that renders the multi-line, you'll see a circle around the object which approximates the footprint.

To receive the object, add o/PSAT*/ to your APRS-IS filter.

PS.  PSAT and the ISS orbits actually crossed earlier this evening off the coast of Africa.  They were definitely within each other's "footprint" (not very applicable when not on the ground) for several minutes.

That's the TLE I'm using in the PSAT SATSRV auto pass responder.  However, it's missing the check digits on each line and most TLE's don't include the + signs.  Your usability of this TLE as provided may vary, but APRSISCE/32 will certainly reject it.

PS.  Any idea when this might get picked up at http://celestrak.com/NORAD/elements/tle-new.txt

Is there a way of locating PSAT?
