Have you restarted piaware after upgrading it? It doesn’t auto-restart on package install (because usually the package install is driven by piaware itself)
You may want to take another look.
It looks like mlat stopped after the reboot.
It says enabled but no neighboring receivers. Have you set the antenna location on the piaware website?
This feeder is not being used for multilateration because its timing information appears to be unreliable. This can be caused by the site location being incorrect, or because your Pi is running out of free CPU.
What is timing information? Location is correct, CPU is running high, but not at 100%.
dump1090 uses Mode S messages to get timing information. It uses this to triangulate positions of Mode S aircraft.
If the information is not accurate or reliable, it cannot be used.
Do you have anything else running on the RPI? Is it a version one or two?
Thanks for the detailed replies. In summary then, if I understand correctly, for MLAT we usually have a non-corrected pressure altitude and that is displayed, otherwise an extremely noisy attempt is made to compute it. However it seems there is no way for me to know which was done. I get I could look for non-smooth changes which would indicated a computed result.
In any case it looks like I still have to do the altitude compensation based on the actual current atmospheric pressure myself.
Any chance of getting a FlightAware feeder with MLAT for x86 or x64 based PCs? Even the first gen Intel sticks run circles around the newest RPi in the way of memory and horsepower.
I did this for the dev 3.0 version
(remove the “-b dev” for the current version).
sudo apt-get install build-essential debhelper tcl8.5-dev autoconf python3-dev python-virtualenv libz-dev tcl8.6-dev python3-venv dh-systemd
(There may be other dependencies. Just add them too).
Not in Alaska where I live! ADS-B will not effect most of the State, only the Class Charlie airspace in Anchorage and Fairbanks. We have more aircraft than all other States combined, but most will not be converting.
I am already running Ubuntu and Dump1090 on this stick. It seems I remember trying to install some packages from a script and got errors alluding to the package only being compatible with Arm.
At this point, with Dump1090 running normally on Ubuntu on this x64 device, can I now install some form of PiAware that is not locked to Arm processors or is that not relevant?
There’s nothing arm-specific in piaware.
(the binary packages provided by FlightAware are only built for arm, but if you’re building it yourself that doesn’t matter)
Perfect. SO, what I’m looking for is some assistance in the way of a more detailed procedure to install said hardware agnostic PiAware package onto this stick. Not very Linuxy here.
