Ursalink LoRaWAN Gateway supports GPS as an optional module, which is used to locate the position of the gateway, it supports GPS currently. The GPS data will be sent to platform connected as well, the time will be 10 seconds every time.
If you cannot get the GPS data, here are the checklist you can refer to.
-
Check whether the Gateway you purchased supports GPS module by Model value in 'System Information' page, which must have Option ''-G '' inside. In this example, this gateway doen't support GPS.
-
Check if the GPS Antenna was connected well, and we need to make sure the signal is good. For example, if the antenna was located in rack room, you will not get the GPS info generally, we need to extend the line and put it to outside.
You will need also check if the GPS antenna was connect to the right port. If it's connected to LoRa's antenna port, no GPS data will appear.
-
You can also download the system log through page 'Maintenance->Log->System Log'.
Try to check the 'lora-pkt-fwd.log', you will find some logs about GPS.
This is the example log of no GPS :
### [GPS] ###
# Invalid time reference (age: 1603184896 sec)
