Radarcape Requirements
For normal operation a Radarcape requires
- a dry place with moderate temperatures
- AC power 100V-240V 50-60Hz, alternatively 5V/1A DC supply
- Ethernet connection
The following optional services are dependent on Internet connection:
| Protocol | Transport | Destination Hostname |
Port | Service |
|---|---|---|---|---|
| HTTPS | TCP | jetvision.de | 443 | Download of software upgrades |
| HTTPS | TCP | jetvision.de | 443 | Download of basestation and flightroutes databases |
| HTTPS | TCP | ddb.glidernet.org | 443 | Download of OGN database |
| Wireguard | UDP | link.jetvision.de | 8251 | Remote support (on request) |
| NTP | UDP | * | 123 | Backup system time syncronization |
| MLAT | TCP + UDP | mlat.jetvision.de | 10011 | Jetvision MLAT flight tracking network |
| APRS | TCP | aprs.glidernet.org | 14580 | OGN/FLARM decoder (Air!Squitter with FLARM option only) |
Software Requirements
Aircraft Data Access
Since the Radarcape does not have it's own display, external software is required for displaying the aircraft data that it receives.
It depends on the users preferences how he wants to get access
- The internal aircraft list (database) and the Live 2D Map can be viewed with any kind of web browsers. The list can be sorted by various parameters (filtering in preparation) and will update automatically in a configurable time.
- KML files such as they are used by Google Earth will be provided and contain current positions and track information. Update rate (and later also contents) of these is also configurable.
- Support for 2nd level software is provided by access methodes to the raw received data or port 30003 protocol data. Such is beeing used by Planeplotter, Globe-S and more.
Note that all services are accessible in parallel without major interaction.
Antenna Requirements
The antenna should be placed as high as possible and as free as possible. Nearby metallic parts should be avoided or have a minimum distance of about 50cm. Big metallic surfaces around, for example metallic chimney casing, may cause reflections and degrade reception in some cases.
Due to the high sensitivity of the Radarcape a preamplifier normally is not recommended. Only if your cable attenuation exceeds 6dB, you may consider using one. The cables we supply with the Radarcape do even with 10m length hold the so called "3dB rule" and can be used without doubts.
The antenna connector of the Radarcape is a standard SMA female connector on the back side.
