I received my S100 earlier today and downloaded the User manual and Android App onto my 2-3 year old phone. Out of the box without looking at the manual I connected to the S100 via WiFi and bluetooth within 90 seconds and was able to do a few autonomous GNSS tests showing 0.5 to 2m accuracy in open terrain. After a couple hours of playing around I followed Phase 2 of the purchase and enabled the full networked RTK functionality. In under an hour I had my activation code and updated the S100. About 5 minutes later, I was up and running with reported 3D RMS error about 7mm with a 16km baseline to the nearest network base station! So far, my expectations have been exceeded.

There are other low-cost RTK systems out there, but the Polaris S100 has a nice form factor and is functional out of the box. I look forward to putting it to use in my geophysical instrumentation and surveying practice.
