This is an important update for all users.
Full release notes to follow , but basically this version when run with a new programme
Dump1090 windows [provisional title] will provide useable raw data for mlats from the 1090 dongles.
Until now the raw data produced by the dongles has not been useable for mlats , but this new software should resolve the issue
There are other important changes which affect all users and will enhance various features , so it is important that everyone updates as soon as posible.
Potentially there are about 100 ground stations who will be able to improve their
raw data by this upgrade together with Dump1090 windows
The latest version of PlanePlotter can be found here

Full details about Dump1090 windows will be available shortly
Great news, I'm one of that GS/MU using a dongle. Updating now and waiting for "Dump1090 Windows"
Well done John.
Will the fixes be added to Dump1090 Linux, or is Dump1090 Windows a stripped down version?
I'm thinking that since PP does all the bit decoding already in windows, that the bit decoding in dump1090 is now redundant and no longer needed.
Hi Edgy
If using Dump1090 with Rpi and PP no change needed , we have established that the raw data from this combo is good
Release notes and where to get Dunp1090 windowsHi,
PlanePlotter version 6.4.1.7 is now available for download following

You may need to exercise your browser Refresh function to force it to
show you the new version of the PlanePlotter web page. If you post a
message saying that the web site is still pointing to an earlier
version, you pay a forfeit !
You can install the new version over the old one but you *must*
close/exit PlanePlotter before installing the new one. Your settings
will be preserved. If you post a message saying that the installer is
unable to replace planeplotter.exe, it means that you did not close
PP first and you pay a forfeit !
If you have a version-specific firewall (eg Zone Alarm), you may have
to reassure it that the new version is permitted to access the Internet.

New in version 6.4.1.7 - in no particular order
New receiver option RTL->PC+Dump1090
This option supports Malcolm's excellent new utility Dump1090 for Windows based on his Linux and RPi ports.
If you have an RTL dongle and aspire to being an effective Ground Station, please follow the instructions here :
http://planeplotter.pbworks.com/Dump1090
Malcolm's version of Dump1090 for Windows overcomes the problems encountered with Ground Stations previously using Andy's RTL1090 and yields raw data with time tags that contribute to Mlat fixes.
You need to start dump1090-for-Windows, using the batch file provided, before you set PlanePlotter processing and you need to select the RTL->PC+Dump1090 option in Options..I/O settings and you also need to specify "127.0.0.1:30002" in Options..Mode-S..RTL dongle-PC-dump1090..Setup TCP client.
In addition to working better as a Ground Station, I get the impression on my test system here, that it also gives better range for normal reception than the alternative solution - but that may be unique to my system so don't hold me to that.
If dongle-based Ground Stations switch to using this new utility, I anticipate a massive increase in Multiateration fixes especially in areas where, currently, there are insufficient of the more expensive receivers to succeed. With this development, the huge reserve of dongle-based Ground Stations should spring to life.
Include alerting ID in TCAS alerts
If you are lucky enough (if that is the right phrase) to see a TCAS alert, it will now identify both aircraft involved in the potential conflict.

eLaReF has suggested better wording for the section on the sometimes vexatious topic of setting up the Home location in PlanePlotter.

Might be worth cross posting that in the Dongle section. Lot of negative comments on the PP Yahoo Groups when I last went there :( about the apparent waste of time setting up Rpi and dongle if it wasn't capable of MLAT.
So for anyone who hasn't been back to the Yahoo Groups recently ;) , and prefers reading their info here, that would be reassuring.
Well done to the PP team (and Malcolm who wrote dump1090).
I always made it quite clear that running an Rpi standalone [without PP running] would not be capable of Mlat.
That might change , but for the present , thats how things stand
Running an RPi with Dump1090 and PP running ,"does" give good raw data for mlat
The main sourse of info is as ever , the PP Yahoo group

Maybe I can embellish the statement:
"the main source of
PP info is as ever the PP Yahoo group."
You're quite right Mike....I stand corrected [ although this was a post in the PP section].....and I spelt [ or is it spelled...or I spelt it wrongly ? ] source wrong :'(

Include alerting ID in TCAS alerts
If you are lucky enough (if that is the right phrase) to see a TCAS alert, it will now identify both aircraft involved in the potential conflict.
In my home-brew, I've been decoding the TCAS alerts here in the states, and they are few and far between. In most cases I get a low level alert and sometimes no bits are set. Rarely do I get an actual bearing, range, and altitude. Semi-rarely do I get the target ICAO of the threat.
I think, since the US still has no mode-s for most general aviation that the TCAS just see's Mode-A/C threats, thus no ICAO to print.
Then too, there's not much data during an encounter. I expected once a threat was detected, I'd get more than one or two hits, but they have been over very quickly. The idea was maybe drawing a dotted-line to the threat and then updating a little diamond symbol. But with so little data, I haven't had the energy to finish the exercise :-)
Every once in awhile I can get an alert from the E-6's. They sometimes have three of them doing crash and dashes, but the tower does a good job spacing them. Most of my TCAS hits are from planes leaving OKC and encountering Mode-A/C puddle jumpers, with light advisories (no big threat).
Sorry to go WAY off topic...
Not off topic edgy , its interesting to hear your thoughts.
Here in central UK I havnt seen one alert yet , thats since TCAS was introduced a couple of months ago.
Thats re assuring....I think :-\
I was thinking it might be a neat way to plot positions of planes that weren't sending positions. Alas, not enough airplanes are flying into each other :-)
