So I’m looking to buy a GPS to use for field surveying - I’m a professional engineer who is looking at doing a side business of drawing plot plans for people in my community to get approved for building permits. I go to the site, connect to the Kentucky Cors base stations, and survey property corner…

Welcome @spud ! I’m happy to answer all of your questions, but I’ll start with a question : Do you have an existing data collector software package that you like ? Many of the professional apps will connect to any Bluetooth GNSS Receiver. Any of the RTK receivers will work with KY CORS network.…

Oh yeah, take a look at this post too. Might be useful to you, as importing layers/linework into SW Maps (iOS) isn’t as clean as the Android version or paid apps. [image] Interactive Deed Plotter with RTK Localization, KML Export, and CSV Reporting SparkPNT / Consumer Pro…

The TX2 is showing in-stock this morning. Tilt compensation is/was a little tricky with the SparkFun RTK Everywhere Firmware. [ Note: I don’t use Tilt, so the following might be outdated] In normal mode, the SparkFun RTK reports the position of the electrical phase center of the antenna, and we e…

Maybe I’m not understanding, but how would a rod height of zero provide an accurate height if I’m surveying with a 2m GPS pole? I’m comparing the RTK Torch, PNT TX2, and PNT RTK Facet Mosaic and I know they all use different GNSS chips but what would that actually change in the field? I guess a bet…

I’ve stumbled across Emlid products now as well and I’m really impressed with their website and products. It seems like SparkPNT is an electronics company that does GNSS vs Emlid being a GNSS company at the same price point. Integrated user-friendly apps and everything…

One other point to consider is how close you are to a cors station. Typically it works within 6km unless your state has a network like we do in Oregon. So if you’re too far from CORS it’s not going to work well. A Kentucky PLS I purchased a receiver from said that RTK via cors/network did not work w…

Some thoughts as somebody who’s supporting a fleet of hundreds of Trimble R-series devices and hundreds of Sparkfuns across the US over the last 10 years: Equal-to-favorable comparison to the Trimbles in the measures you called out. Devices from both manufactures will deliver exceptional accuraci…

Good feedback! Im sure this will be useful for @sparky to make these devices even better in the future.

I have changed my mind. Most users won’t notice a difference, and there likely isn’t one
