For monitoring the internals an additional temperature and humidity sensor is added to the baseboard. This baseboard acts as a mounting plate for the BeagleBone, the PoE (Power over Ethernet) and other power modules, the two ZED-F9P GNSS units and an optional communication module (e.g. Cellular, LoRa or Radio).Additionally, two Taoglas multi-band (L1 and L2) active GNSS antennas were selected to receive up to 180 GNSS channels. To display the information from the two high precision GNSS modules, there is a web interface that is showing the real-time data. Powering the unit by PoE (Power over Ethernet, 802.3at) makes it possible to connect the complete unit using just one cat5e cable, with a maximum length of 100m.
All communication to and from the unit is done by using the Ethernet connection. The IPv4 Ethernet connection can have 2 IP-addresses, a DHCP address and also a fixed address. This makes it possible to use the unit, without modification, in a network without DHCP and DNS server. There is no need to open the unit to change settings, the complete configuration is possible by the web-interface. The used IPv4 communication protocols are http, web-sockets, sockets, telnet and ssh. All hardware is selected to build a heavy-duty, long-lasting and flexible system, suitable for harsh environments. With the flexible software architecture it is possible to keep the units up to date and ready for future requirements.
