Here’s some cool software that’s free and open source, Surveyors Applications for Least Squares Adjustment (SALSA). It was developed by the Applied Research Facility at the University of Texas, Austin.
It was funded and supported by the National Geospatial-Intelligence Agency. It can adjust GNSS observation vectors and standard terrestrial observations .
I’ve downloaded the software and manual but really haven’t had an opportunity to start using; Metashape is taking up most of my free time
Pretty cool software, cheaper than MicroSurvey’s Starnet adjustment package. It would be cool if Emlid would incorporate this into Emlid Studio !
