so you are saying that i don’t have to use emlid base and i can process with different base log file from trimble/leica and use emlid to fly PPK and process my data?
The beauty of the Emlid Reach is the low cost. If you already have access to a high-cost survey-grade receiver by Trimble, Leica, Hemisphere, Topcon with raw measurement logging, you can elect to use that instead for your PPK reference data.
All of these manufactures have utilities that will convert their proprietary binary log to the common RINEX format. The UBX format is exclusive to uBlox, which powers the Emlid product line.
