RTK Accuracy with Collector for Stream Monitoring
Track: Environmental Management
Authors: Jeff Comstock, Matthew Alexander

To increase stream monitoring accuracy, Collector recorded 3D high-accuracy positions from an Eos Arrow 200 RTK GNSS. With no internet access for RTK an Arrow 200 base station sent RTK corrections to a mobile unit via 900MHz radio link. This configuration collected cm-accurate data with the base receiver collecting data for post-processing via OPUS. Corrections were applied to mobile positions. Collector recorded ecological conditions and photos in a disconnected mode and synced to our Portal.
