Radarcape Major 2 Features
General notes for new software releases
- All new Radarcape firmware packages have been tested thoroughly, but since Radarcape is an open system we never can now all status of devices that run on your side. In case of updating problems, please consider updating your device manually using the debian package or flashing it first back to a fallback image, as described in Radarcape:DebianSupport#Debian_Installation.
- Especially when operating your Radarcape remotely from your own location, be aware that the update may crash and you need to have a fallback strategy, a 2nd port for commands, and maybe the watchdog retrigger script running or at hands: Radarcape:Watchdog. It is highly recommended in such situations that you update first some local devices in order to proof it will work remotely, too.
For updating, please use the built-in web service menu: Settings -> Software Maintenance -> Radarcape Software Update. The latest software version automatically should be displayed there.
Radarcape Software Features Version 181213.1000.02 (Major Release 2)
- New Features:
- Decoding of Flarm PFLAA frames on UDP input port 50001
Note: PFLAA must have absolute LAT/LON values and not X/Y offset location for this feature.
- Decoding of Flarm PFLAA frames on UDP input port 50001
- Improvements and Changes:
- Config file now only records non-default parameters
- Software type and version are now displayed separately.
Type is "AAA" for a standard Radarcape with Debian 8 Jessie.
- Data corruption on JSON over UDP and TCP 30002 output.
- Bug causing error message "PPS/Time reference configuration error"
- KML output swapped LAT/LON
- Use default ports for network streams
- Wrong ntp time output
- Flightradar24 in some cases is not accessible because their IP V6 address is not accessible. This is a misconfiguration on Flightradar24 side which we cannot influence. Please ask firstname.lastname@example.org for advise.
- Some users reported Flightradar24 has lost their user login key. Please contact email@example.com in case that the feeder cannot connect to their server.

Radarcape Software Features Version radarcaped-170521.1100.02 (Major Release 2)
Since May 2017 we provide Major Release 2. Currently this page describes the differences to Software Features of Major 1. All features of Major 1 are still included into Major 2, however some, for example the JSON lists and KML output, with some changes or enhancements.
Listed here are a lot of add-ons and enhancements. Please read across Radarcape:Software_Features for a first overview. See more about installations in the bottom.
You can identifiy our Major 2 release with a ".02", ".02D" or ".02A" at the end of the version string while Major 1 is ".01", ".01D", ".01A" or nothing.
How to perform update
It is strongly recommended to update to the latest version of Major 1 before updating to Major 2.
Until now the update has been done on some 50 devices without problems or assistance, most of them even remote. However, if your device is in a barely accessible, remote location or otherwise not easy to handle if something fails, please wait until some more experience was gained. We do not take over guarantee that it works in any strange situation.
If you want to update, simply go to the Settings - Software Maintenance and overwrite the default version given with the string
and then press submit. Thats it.
This is a brief summary of all new features.
We now have our own multilateration network operating stable with very good results.

Changed License Conditions
With Major 2 firmware, we are introducing 3 classes of software licenses. Major 1 software (versions yymmdd.hhmm.01) are not affected by this change.
For private users, there are no changes, they can use the Radarcape in their private environment as always before! With Major 2 release, the license type is shown in the browser title. Default license type is "non commercial".
For business purposes, when using Major 2 release, you need a commercial license key in case you use our Radarcape to generate commercial value (excluding value generated by using the built in feeders). For non profit organisations it is further free without a payable license. Please contact Jetvision support for a feature key.
The feature key key is available also in the shop, please provide your Status - System: Download TXT file with your request.
This license is for using the Radarcape with Major 2 software for OEM purposes. This license key allows to customize the browser interface, use own logos and style sheets. Radarcape and all interface data can be used for business purposes in a customized environment.
The feature key is available also in the shop, please provide your Status - System: Download TXT file with your request.

Radarcape Software Features
Sharing Groups (planned)
- A number of Radarcapes can be combined through our server forming a sharing group, e.g. for wide area supervision or local hot spot precision observation.
- Radarcape MLAT results are shared within such a Sharing Group (third party sources are not)
Filters for 2D or KML
- Altitude, Type (with wildcard), and more
- Fleetwatch Filter:
- Filtering for ICAO HEX ID or registration (wildcards permitted)
FlightAware no compromise feed including multilateration results
- FlightAware sharing supported with no compromises
- MLAT results from FlightAware feeder can be read back into the Radarcape in addition to MLAT results from Radarcape network. The border of aircraft symbols indicates the source
- black: ADS-B
- red: Jetvision MLAT
- green: FlightAware MLAT
Location and flight paths of different sources are stored and output separately
- ADS-B, Radarcape-MLAT, FlightAware-MLAT and Sharing Group results may be observed separately
- These data are also available within the JSON data outputs
- A new field was added to aircraftlist.json which contains the location, altitude, heading, speed and vertical rate for each of the location sources
New feeder for Opensky Network
- Opensky network feeder with no compromises
How to install is explained in the Settings - Radarcape Feeder Settings - Opensky Network page
Automatic update of routes and aircraft type database
- Flightroutes database and basestation database are updated automatically (internet connection required), however manual update is still possible.
- Manual upload service for systems without internet
GPS data is provided to Chrony or NTPD
- The Radarcape becomes a stratum 1 time server
Optimized TCP streams
- In order to decrease network load, network streams became buffered
Signal level in dBm
- The signal level at the antenna connector is indicated in dBm
(note that this is not foreseen for measurement purposes)
Second-of-Day mode selectable
The value range of the second-of-day field in the GPS timestamp is selectable, the current setting is reported in status frame
- legacy mode: value range is 1…86400
- true UTC mode: value range is 0 … 86399
Status Frame 0x34 contents were extended with GPS and UTC information
- Status frames are triggered by 1PPS pulse when GPS timestamps are selected and triggered randomly in case of legacy 12MHz timestamps.
- Status frames contain a valid timestamp
- The signal level value is zero
Byte #0 of the message part contains a mirror of the FPGA switch settings. These settings have direct effect on the raw data ports 10002-10006 and indirect effect due to eventually missing or differently available data to the high level functions:
|Bit 0:||Data output mode
(port 10002 only)
|Bit 1:||Raw data frame types||DF11, DF17 and DF18 only||no pre-filtering|
|Bit 2:||Timestamps within AVR format||enabled||disabled|
|Bit 3:||not used|
|Bit 4:||Timestamp mode||GPS||Legacy 12MHz|
|Bit 5:||FPGA/USB handshake||disabled||enabled|
|Bit 6:||1 bit forward error
|Bit 7:||Mode-A/C decoding||enabled||disabled|
Byte #1 of the message part in GPS timestamp mode contains the offset of the nanosecond timer at the 1PPS event in units of 15.625ns. Normal value range is -3 … +3.
Byte #2 of the message part contains information about GPS
|Bit 0:||Antenna status||good||fail|
|Bit 1:|| Tracking at least
|Bit 2:|| Tracking at least
|Bit 3:||Time value base||UTC time|| GPS time|
|Bit 7:||Daysec value range||0 ... 86399||1 ... 86400|
New responsive web design
- Optimized for web browsers, mobile devices and tablets
Configuration and filters stored in local browser
- Filters are provided for serval properties, like altitude, hex code, registration and type (with wildcards), speed, and more
- Views and filters from different browsers and devices can have individual settings, e.g. different map styles and filters
Openlayers Map introduced in parallel to Google Maps
- Supports different map styles based on gmap and Openlayers
- Border of aircraft symbols and color of tracks shows the source of data
- Black: ADS-B
- Red: Radarcape-MLAT
- Green: FlightAware
- Track is colored by source or altitude (partly implemented)
- Professional Radar map style
- providing only navigatorial data
- free of unwanted map contents
- Track and vector displayed of each aircraft
- border color is data source: black=ADS-B, red=Radarcape MLAT green=FlightAware MLAT
- fill style blue=climbing, yellow: leveling, brown=ascending
KML output for 3D external viewers
- KML output has got 3 filter banks within the Radarcapes, which can be selected in a KML browser separately or even in parallel. Unlike the 2D maps, common KML browsers like Google Earth do not permit adding user specific menues, so this way was choosen. However, these filters are updated without the need of reloading in the KML browser, just submit the new filter and it applies at the next reload.
KML output provides aircrafts in different colors:
- Outer rim:
- Black: localized by ADS-B
- Red: Jetvision MLAT location
- Green: FlightAware MLAT location
- Inner color:
- Yellow: no change in altitude
- Brown: descending
- Blue: Climbing
The color of the track is selected by altitude, and ground tracks are colored in yellow.
Chrony and NTPD Support
Radarcape software provides interfaces for Chrony and NTPD so they can access the GPS data properly. With these, Radarcape becomes a Stratum 1 NTP standard.
Changed Output Formats
In case that the changed output formats are causing impacts with any 3rd level software that we were not aware of, please contact us in order to find the best suitable solution.

- The location, altitude, track, vrate and speed given for the aircraft in the base level follows a priority: ADS-B -> Radarcape-MLAT -> FlightAware MLAT, whichever has provided more results during the last 5 seconds
- The values of the currently three location sources (ADS-B, Radarcape-MLAT, FlightAware-MLAT) can be requested in a separate array with an additional URL parameter &select=loc. Each of them contains a field "tsz" for its track length. Base level elements "tsa" and "tsz" were removed
- Value "dbm" was added, which contains the signal level at the antenna connector in dBm. Note: This is not for measurement purposes
- The values itself are formatted as their native data type (integer, string, float). No longer for example floats as a string. Unknown values are marked as JSON 'null'
- removed without replacement
- now outputs a JSON array with the capability to request several flight paths in one call
- used with parameter "&icao=<hex>" will return the flight path by default priority ranking ADS-B -> Jetvision MLAT -> FlightAware MLAT, an additional parameter "&src=<char>" with char either 'a', 'm' or 'f' will select the flight path from selected location source
- parameter "&icao=<hex>" may be either repeated or either be filled with a comma separated list (e.g. <hex1, hex2>) to request several flight paths
- instead of <hex> it may also contain registratioin, this can be mixed, so for example these are valid requests: &icao=3f1234,D-AQUI or &icao=3f1234&icoa=d-aqui. Using registration requires a loaded aircraft type database and the presence of the aircraft in this database.
- contains information about own location and some more
deltadb.csv / deltadb.txt
- parameter "&loc=" was removed, own location can be read within mapinfo.json
UDP Output and Formats
- The configuration of all UDP ports was separated from General settings into a streaming output configuration page
- A new UDP format which contains a periodic output of changed data in the same format as aircraftlist.json is now provided.
The time interval between each output can be configured.
