What are the additional equipment/software needed with GSG-8 to measure timing accuracy of the GNS receiver?
Hope you are doing good!
You don’t really need any additional equipment/software. You can use the synchronization receiver (CDM5) that is already integrated in the GSG-8. Then connect the 10 Mhz signal from the CDM5 sync receiver to your GNSS receiver and use an oscilloscope to compare their different PPS. We can provide assistance in testing the accuracy of the synchronization with your GNSS receiver and the GSG-8.
In addition to Grace’s answer above, you can also refer to the following document on the Orolia website:
