The gateway has a built-in GNSS module which is used as a source of accurate time and location. GNSS settings are known in the LTE modem settings tab.
Manual GPS
The location is needed for the solar timer system. In some situations, the gateway is placed in such a location that it does not catch the GNSS signal, and for this purpose there is a manual GPS option. To use this option, you need to enter the longitude and latitude manually.
Powering the active GNSS antenna
The gateway has the ability to accommodate both passive and active GNSS antennas. The supply voltage of the active antenna is 3.3V. To enable the power supply, select Antenna power supply ON.
