[OZAPRS] APRS sat settings

The seems to be diversity of paths used for the ISS.  I think Ray's 
observation (VK2TV) is pretty well on the money.

However AFAIK the ISS is the only satellite operational at present, and 
even then the digipeater goes 'off air' at times for a variety of 
reasons - EVA / docking with another spacecraft / school contacts and 
other events.  It's currently been off air for nearly five days as I 
write, so it's not as reliable as one might hope ( I speculate that 
sometimes they simply forget to turn it back on again). The other factor 
can be that its orbits over a given spot on the earth's surface are such 
that a mobile station might only be heard for a series of two or three 
passes in any given 24 hours.   There are (from memory) about three 
satgates in the SW of WA and from what I can see, VK5ATN-3 is the only 
one in SA.   There are a few more in the eastern states one in Tassie.   
The coverage over AU is pretty good but a satgate in the northern part 
of the continent would be welcome to fill the gaps that do exist. Even 
so, some satgates in Indonesia do have a reach which does extend 
coverage into the northern and central  parts of WA.

Personally I would still choose 30m for that kind of trip - I think that 
on balance you'd be 'seen' far more often on there than what the ISS is 
able to offer.  In the meantime keep an eye on http://www.ariss.net/  
and watch the orbits on a program of your choice.   At present, the ISS 
offers useful daytime passes for Australia, but in time that will change 
(as it does) to passes possibly less favourable for the intended purpose.
