– E1 RTK GNSS GPS Base Station Receiver for Land Surveying, High Accuracy Survey Grade Positioning, Static Survey, Topographic Mapping, Point Stakeout & GIS Data Collection

Great antenna and even better software. All Cogo functions you would need to calculate alingments, slopes and surfaces on site, and even export lines in cad and surfaces in landxml to machine control on site. The brand also responds very quickly if you have any question. I 100% recommend it.

When professional surveyors wanted $7000 to stake out my rural property lines, I sought an alternative. This unit did the job. It is accurate to within a centimeter. In order to operate as a single rover I had to subscribe to an RTK service for achieving that accuracy by tethering to my cell phone internet. The unit does not need to be plumb after initial setup. The RTK service acts as a base. To be accurate without the RTK service requires a second unit set up as a base at a known location.

Amazing performance from this E1 set! 5 stars over 4 because of strong customer service. There are some gaps in written documentation. However, Support was very responsive by email. I use the kit as base/rover (UHF data link) to set GCPs for RTK drone photogrammetry and then I use base mode to broadcast NTRIP on Wi-Fi for my ground station during drone photo collection. Between the insight from the SC200 UI and help from Support I was able to configure correctly. In my case, the missing step was logging into the base E1 with a laptop Wi-Fi to actually enable NTRIP. Once that was done, I was fully up and running. I probably could have had even faster response if I had used the WhatsApp option instead of email, but I always received a response within 24 hours! Thanks!

Good quality and affordable GNSS antenna. The software connects easily, and tech support was excellent and extremely responsive.I would recommend this 100% as a great system, on par with name brands that cost exponentially more.
