Good day,
We are testing Emlid Reach RS2 for measuring utilities. So far our surveyors used Trimble but we are looking to involve more people into the survey process by letting them use Arcgis Collector and some external GNSS device. Our choice for external GNSS receiver was Reach RS2. However, there are some issues that we observe with a new workflow.
First of all, out tests using ReachView native app showed very nice results both in horizontal and vertical accuracy. Recently added vertical datum for our region (Iceland) works very well and all height values are in accordance to the National Land Survey data. However, when same locations are measured in Arcgis Collector, the altitude always varies and sometimes the variations are up to 0.5 - 1 m. I did several tests and all of them showed stable altitude in Reachview app but ranging values in Collector. I wonder what might cause these variations. Has anyone experienced the same issues using external GNSS (particularly Reach RS2) with Arcgis Collector?
Cheers
