Satellite tracking via the APRS-IS is almost completely useless! There are
numerous well-meaning but misinformed users attempting to feed satellite tracks
to the APRS-IS.� Unfortunately, most of them are incorrect or incomplete.� You
get two or three objects for the same satellite in different parts of the world
at the same !
Or the data is very locally oriented - i.e. useless messages such as "ISS
signal acquisition in 5 minutes" without saying WHERE. Obviously such a report
would only would apply to one point on the earth's surface.牋 It might make
sense to beacon this kind of information on local RF, but is pointless on a
global network like the APRS-IS.
The one satellite track object that does work correctly is KJ4ERJ's space
station object injected from his virtual (simulated) igate. This beacon is
updated every two minutes and shows the station's actual location.� It draws
both a point object for the station's location, and a circular area object
centered around it that shows the station's radio footprint on the ground. � �
The point object renders correctly on all APRS client programs, but the area
object is only displayed correctly on UIview.
You can receive this object by adding the entry point filter u/APZTLE牋牋 to
your existing port 14580 filter port expression. It might seem that filtering
for the object name with an expression like牋 o/ISS* 牋 would be the obvious
approach.牋 But it doesn't work, because several other users on the APRS-IS are
gating junk under the same alias (ISSxx)� which results in two or three space
stations at the same time, at different locations.
By the way, the digipeater on board the space station is� currently NOT
WORKING.� The only digipeats currently being heard on 145.825 are from "PSAT".�
These are much harder to hear since they are coming from a cubesat with a
fractional-watt transmitter, compared to the ISS digi that used a 5-watt
transmitter.牋 It appears that the ISS digipeater will not return to service
until late this summer or next fall when new Kenwood D710s will be sent to the
station.
