So where is the heading on PP coming from? An SBS sharer I presume if you're saying that RB isn't decoding heading on the port 30003 output.

HI Tom and thanks. I found him showing on the RB just afer I posted he was heading NW. Indeed he became visible SW of my home location., though the heading didn't appear on the box.

SBS doesn't output heading either (only track), but in this case said C-37 doesn't broadcast track (although of course it's possible to derive average track from successive lat/lon reports).

Westbound, at present just passed BPL,Trailing well. RCH 851.  02-1112. One for you Canonjohns?

Cheers Hawkeye not visual in some cloudcover but still looking. The Airfrance A380 is also due overhead in a few minutes.

In this case I was not using mlat and the bearing was shown in PP under 'course', so I assume the ac was sending it.

To clarify, that C-37 sends ADS-B Airborne Position squitters (which is why it plots on BaseStation) but doesn't send ADS-B Airborne Velocity squitters (hence no groundspeed or track on BaseStation).

It may send track and/or heading as EHS DAPs, but none of the enthusiast Mode S receivers decode these, so the PP course value can only have been derived from successive ADS-B position reports.

I'll have to ask Bev if PP does that automatically as I was not aware it could.

According to John on the PP group it uses the prediction feature to plot a course from the position data. Should have realized it myself :-(

Very interesting this callsign, did not know that now the U.S. Air Force flight in High Definition. :)

Bit late to post, but I had a visual on that SPAR76 Canonjohns40D as it passed over Leicester.

I've been watching Australian Air Force A36-001 7CF85C  ASY373 in a holding pattern for a ramp freeze at KADW.
