Stratux Europe Edition 1.6r1-eu025

Link zur Download-Seite (GitHub)

Major-Update: Das heißt es muss die Software neu auf die SD-Karte geflasht werden. (kein .sh-Update für diese Version)

Da es sich ab jetzt um eine 64bit-basierte Softwareumgebung handelt, werden nur noch RPi ab der Version 3B und neuer unterstützt. (Pi Zero auch nicht)

Wird die Einheit zusätzlich mit einem TTGO-Beam (OGN Tracker) betrieben wird empfohlen die Firmware des Beam ebenfalls zu aktualisieren, da es auch hier Verbesserungen gab.

Bitte nicht vergessen den Browsercache zu löschen (auf dem Anzeigegerät), wenn neue STRATUX-Software installiert wurde!

Hauptänderungen:

  • Neues 64bit RPi-Betriebssystem (aarch64)
  • Option zum Einstellen der Sendeleistung des optionalen OGN Trackers (TTGO-Beam) wurde hinzugefügt
  • Bessere OSM Karte (online + offline Option)
  • Auf dem RPi4 wird nun auch immer ein 2,4Ghz-Wlanspot erzeugt, da ältere Geräte 5Ghz-Wlan oft nicht unterstützen.
  • Sowie viele weitere Verbesserungen. Siehe für mehr Details in die Release-Notes der offiziellen Seite

Änderungen:

This release doesn’t have too many exciting new features, but a lot of small improvements all over the place.

Reworked GPS Handling code

  • Removed parsing of proprietary PUBX messages, using standard NMEA now
  • Lots of improvements to standard NMEA parsing
  • Fixed issue that number of satellites in view on the Status and GPS page could jump around a lot
  • Improved chip configuration (SBAS, Galileo) for Ublox
  • Improved computation of GPS Accuracy. Note that Accuracy might show a bit worse on the web interface now. This is only due to rework of the precision estimation – it is not worse in reality.

Improvements to OGN Tracker firmware and interface

  • Firmware is now compiled with WITH_LORAWAN for Lora support
  • Improvements to PilotAware and OGNTP transmission timing. Transmission is now more regular to make it more reliable
  • A few other small improvements, see here: https://github.com/pjalocha/esp32-ogn-tracker/commits/master
  • When using OGN Tracker, you can now configure your aircraft registration, so it will be displayed to other Stratux users even if it is not registered in OGN DDB.

Other

  • New setting to configure a pressure altitude offset, can be used to work around an imprecise BMP280 sensor (#83)
  • Improved barometric altitude estimation from ADS-B if no baro sensor is connected
  • Added option for the Stratux EU case to include a lead-through for a velcro-strap to secure a battery pack (#89)
  • OGN Receiver module now also receives pressure information for a future OGN transmission PI HAT module
  • Fixed issue that Mode-S distance estimation was not done for some targets

If you run OGN Tracker, you might also want to upgrade your OGN Tracker firmware to benefit from new features there. You can do so by following the steps described here:

Änderungen:

Extend your Stratux with transmit capabilities, to not only see, but also be seen.

New build variants and guides

  • The Wiki now features 3 build guides, including one of them that implements transmit capabilities for various 868Mhz protocols
  • A new 3D-printable and customizable case has been designed to accommodate the transmit hardware (don’t have a 3D printer? there are plenty of 3D printing services that can print the case for you for ~15-25€). The case has been designed in OpenSCAD and is therefore very easy to customize to fit your needs. It offers enough space to also include a TTGO T-Beam device (see build guide 3)
  • If you decide to equip your Stratux with an OGN tracker, you will even be able to receive more traffic as well: When a PilotAware ground station sees you transmitting the PilotAware protocol (which the OGN tracker will do), it will re-transmit Mode-S target positions that have been determined by Mlat
  • See here for more information: https://github.com/b3nn0/stratux/wiki/Building-Stratux-Europe-Edition

You can – of course – help extending the coverage of PilotAware base station by hosting one yourself at home. Check the PilotAware website or contact them for more information.

This probably makes Stratux Europe Edition the most capable traffic awareness device available – at extremely affordable cost.

New features, improvements and fixes

  • Implemented first-class support for connecting a TTGO T-Beam based OGN Tracker, including configuration from the Stratux web interface
  • Improved parsing of NMEA traffic message from external devices providing them
  • Added support for MPU9255 IMU
  • Several improvements to 868Mhz reception and protocol handling
  • Improvements to UBlox GPS chip configurations (mainly enablement of SBAS (WAAS, Egnos)
  • Bugfixes to Fancontrol daemon
  • Possibility to set the minimum fan speed manually. This way, you can now set the fan to a speed where it just starts turning to have a constant mild airflow over your SDRs and CPU (requires Stratux AHRS module)
  • Fixes to GPS NMEA parsing in general and SV numbering (thanks to @VirusPilot)
  • Included Stratux-compatible OGN Tracker firmware in the images, with an easy way of installing it directly from your Stratux, see here
  • Fixed detection of Stratux UAT Radio
  • Corrected ID conflict handling between ICAO and non-ICAO aircraft IDs
  • Multiple minor bug and crash fixes all over the place
  • Some minor improvements to the web interface
  • Improved logging: if the Stratux service ever crashes, it will now write information to the log file that helps in finding the cause of the crash

Known issues

  • OGN Tracker configuration for „Pilot Name“ may not contain any whitespaces for now
  • Due to the nature of the many changes, there might be issues related to the new features. However, regarding the old features, I expect this version to be more stable than previous versions
  • If you want to install OGN Tracker Firmware directly from your Stratux, you must install this version by re-imaging the SD card. If you use the update-*.sh, you will not be able to install the firmware.

Änderungen:

Quite a large release this time around, with user facing and structural changes:

OGN Receiver now has a status page on http://192.168.10.1:8082 with detailed information

Stratux now accepts NMEA on port 30011. This can be used to wirelessly connect an ESP32 OGN Tracker and use it as a traffic/location source

Extended the main Status page to include information about OGN noise level and a link to a spectrogram (see screenshot below).
The OGN Noise bar switches color from green to red, depending on the noise level. Reception range decreases by 50% for each 6dB of noise, which is shows as the „range loss factor“. 
Please note that, in order to optimize noise, you have to test in the aircraft while flying. Noise varies widely depending on your surroundings. To proof that, e.g. look at the noise levels with your Stratux beside your desk with a PC vs. going outside with a power bank. This can easily cause a drop of 15dB.

Stratux now contains a „Map“ page which shows all received traffic on a map. See details and screenshot below

Switched from ancient Stratux/dump1090 to actively maintained Flightaware/dump1090 for ADS-B reception

Added identity decoding also for AltitudeReplies (by TomBric)

Small fix to NMEA PFLAA output, which could cause SkyDemon to not show a specific traffic aircraft in rare instances

Please make sure to clear your browser cache after installing the update.

Status page

Map

Aircraft become transparent when they are not received for some time, so the more intensity the color has, the more recent its position reception is

Aircraft are colored depending on their protocol as usual (blue for ADS-B, green for OGN and brown for UAT)

A ~5nm track line is shown for each aircraft

You can choose between a low-res offline OpenStreetMap background, a high-res online one, and OpenAIP (also online)

To make use of the online layers, the client device (phone/tablet/PC) needs to have an internet connection. If it doesn’t, only the low-res map is usable

Änderungen:

Added Mode-S identity reply decoding to more successfully resolve the callsign of Mode-S targets

Fixed relative bearing computation in NMEA PFLAU traffic messages

Removed Stratux OLED status display support for now, as nobody seems to use it and it doesn’t work on python 3 any more [help wanted]

Improvement to Mode-S bearingless target distance estimation

Changed „Bearingless target“ option to only affect GDL90 bearingless emulation with the 8 fake-targets, not NMEA output.

Improvements to „Radar“ page

Minor fixes to „Traffic“ page

Favor GNSS over Baro altitude for OGN targets, as some trackers transmit invalid baro alt

„Show traffic source in callsign“ option now distinguishes between the individual OGN protocols

Included the following updates from mainline Stratux:

Added support for new Stratux AHRS Module (untested, as I don’t have such a module. Feel free to report back)

Added Dark Mode to web interface
