Antenna ground box
The antenna ground box provides access to the antenna on the vessel from a laptop or tablet running QGroundControl. The station is composed of
- Pololu D24V50F5 5V DC/DC converter to provide power from 24V power input
- GL-AR750 access point to access mavlink via Wifi
In addition it is possible to connect via the FTDI UART/USB cable with and without power from the 24V system. The router can also be connected with an ethernet cable to have wired access to the telemetry data.
Connections
- 24V power supply from Ship (max. 3A / 6V-38V InputRange)
- Antenna cable with N connector for the Taoglas antenna
- Ethernet cable for wired access
- FTDI UART/USB cable for direct wired access
Jumpers
- Power Switch: Use Power from D24V50F5 DC/DC Converter (Jumper Left) or the USB Power via FTDI Cable (Jumper Right)
- Data Switch: Route the Telemetry RADIO TX/RX to Ethernet (Jumpers Left) or to the FTDI Cable (Jumpers Right)
Mechanical
The electronics is in a Spelsberg box with 300x300x180mm and pole mounting.
- GEOS MSS-30 Masthalterung mit Schraubschellenset SRS 60-90 und SRS 90-150 und einer
- GEOS-L EP-3030 Montageplatte mit (NOT USED)
- GEOS MH-22 Halterset (WRONG!!! This is too long and probably useless)

Installation
The installation requires
- 24 DC power supply cable
- install of the Taoglas Antenna
- install of the Spelzberg box
- optional install of the Ethernet Cable for fixed wire access
The image shows the installed SearchWing Antenna Box on the Alan Kurdi. The box contains a Wifi Access Point for a connection to the flight tablet computer. It is therefore recommended to operate the tablet in proximity to the box.
