Placing a GNSS base in remote areas is challenging, especially if you don't have an onsite survey mark and a nearby CORS or NTRIP service. If this is your case, this video shows how to use online post-processing services like AUSPOS, OPUS, CSRS-PPP, and IBGE-PPP to get precise coordinates for your base position.

We’ll explore how to record base logs with the Emlid Flow app, submit them to the post-processing service, and how to integrate processed coordinates back into your workflow. This is a reliable method when accuracy can’t be compromised, even in the most remote locations.
