[Xastir] Does anyone know Hessu's email? Was:Re: APRS.FI ROBOT irritation

[Lynn W. Deffenbaugh (Mr)]

Just take a look at the raw packets for KJ4ERJ-15.  aprs.fi doesn't like 
the ISS and PSAT objects "flying" in orbit. They show up fine in other 
APRS clients, but not aprs.fi.  Such is life.  We live by the choices of 
the authors of software that make them available to us for free.

In APRSISCE/32, I monitor the average speed across multiple packets.  If 
a single packet exceeds an internal speed limit, it gets dropped.  But 
if the station appears to be sustaining that speed over time, the 
packets will eventually be accepted as "real".

These are all attempts by APRS uthors to filter the APRS-IS stream to 
remove packets that appear to have been corrupted.  It is thankfully not 
common, but sometimes a station will appear to "jump" back and forth 
across the planet and it's better to suppress those jumps as being 
likely incorrect than to deal with the outcry of bogus-looking tracks.

In the case of aprs.fi, I would have liked to have been able to see the 
raw packets when they were being flagged as "too fast" because it was 
either a short-lived phenomenon (if your station was consistently 
beaconing a new location) or there were two instances of a single 
callsign-SSID beaconing two dramatically different locations in an 
interleaved fashion (which would be user-end correctable).
