I've been using Pathfinder Office and TerraSync for awhile now, but I've always know what coordinate system the data were collected in. I've received an ssf and I have no idea what coordinate system it was set to in TerraSync in the field. I know technically you're only getting lat/lon from satellites, so does it matter what I have it set to in PFO? Is it essentially for display and export purposes only? I know after I deferentially correct and export it uses whatever projection the map was set to. Thanks.
