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
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
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.
PLEASE MAKE SURE TO CLEAR YOUR BROWSER CACHE AFTER INSTALLING THIS VERSION
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.
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
