GPS Receiver - Ground Control Points

[Jarrod]

Hi Guys,

I fly and Evo II and am looking at purchasing a GPS/GNSS receiver to record my ground control points.

Has anyone purchased a hand help receiver to do this? If so what Brand/Model?

I will be using Drone2Map in ArcGIS for processing Orthos and 3D models so am just looking for a receiver so I can add the GCP coordinates before processing.

TIA for any info

Reach RS2 by Emlid | Multi-band RTK GNSS Receiver for mapping

Multi-band RTK GNSS receiver Reach RS2 is designed for professional land surveyors and features built-in LoRa radio, 3.5G modem, and a survey app for iOS/Android.

The RS2 is a good bet because you can use it as a base station also (kind of, sort of, with some screwing around).

I really like my North SmaRTK network rovers for capturing ground points. More of a 'survey grade' type solution.

I have the RS2 kit, they are pretty good.

I did see that the Juniper Geode now is multi-frequency and may be useful if it has the NTRIP functionality..

I also just saw Stonex has a nice small L1/L2/L5 GNSS module that looks interesting: S580 GNSS Receiver - Stonex

Thanks for the replies guys. I have looked over the receivers mentioned above and others. I am thinking I will get a Trimble DA2 with Catalyst on demand subscription..

I have zero idea where you are in the world, but in the USA, surveying GCP's and creating mapping products is covered in most of the states land surveying laws and is a licensed activity. (I say most because I am not familiar with all 50 state laws, but likely all very similar) I am licensed in five western USA states and the activity you describe would be in violation of the law in all five states. Just a FYI.

Here is typical language:

“Practice of land surveying” means that branch of the practice of engineering in which:
(a) Surveys are made to determine area or topography, to establish or reestablish land
boundaries, corners or monuments or to subdivide or plat land;
(b) Surveys are made to establish lines, grades or elevations, or to determine or
estimate quantities of materials required, removed or in place;
(c) Surveys are made for horizontal or vertical mapping control or geodetic control; or

To your question, you will need a phase based GNSS solution receiver to get any accuracy that is usable, sometimes called survey grade. The RS2 kit falls in that class as do many other receivers. Something like the RS2 is probably on the low end of cost for that type of receiver. It looks like DA2 will work too with the subscription.

Hi Shelby,

Thanks for that information. I am in NZ as far as I am aware there are no laws that restrict the activity I am carrying out... but I will investigate further for sure.
