Thanks for the response. I am not an expert in the field so please bare with me!
Lets take a surveyed, engineered and designed site plan ready for bid by the local contractors. Said contractors currently own TopCon base and rover package. I am familiar with the GR-5 and the Hyper V systems so I will use those for discussion. In order to get a quick overview of the site, cuts and fills etc. the contractor would setup his base over an unknown point, say a post at the corner of the site and then use his rover to find and lock on to five control points throughout the site. From there the contractor could walk the site taking topo shots at approximate intervals or attach the rover to a 4-wheeler etc and auto-topo the entire site. From there you are importing your information into Magnet or some other software to create your cut and fill map / 3D map etc.
Taking this another step further in order to minimize time spent onsite the contractors in our area can subscribe to TopNet live or the Oregon ORGN network which provides them realtime RTK networked over wifi. Granted the lag induced into network operation makes for somewhat degraded RTK data but not much. I have done testing in the past that I cannot reference to right now due to misplacement but I will concede the accuracy is a little less than having a base station setup onsite. Since we are only using this data for 3D modeling and not machine control in my opinion this is not an issue and it saves the time of setting up a base station.
Now we add drones into the mix. In my opinion setup time is about the same as a handheld rover system but time on site is extremely reduced. Sites that may have taken 2 or more hours to topo are now taking 10 minutes to fly. My knowledge of the Drone Deploy system may be lacking here so please correct me if I am wrong. Currently Drone Deploy offers some form of RTK correction but I do not believe it includes onsite base station / hardware RTK correction compatibility, only some form of software compatibility. I have heard a rumor they maybe trying to implement hardware RTK compatibility, would it not be easier for them to instead implement network RTK? Currently our smartphones provide commands from the Drone Deploy app to the drone remote and then to the drone itself. What if at the same time our networked RTK smartphone could also provide the RTK data in order to greatly improve our drone GPS accuracy? In my head this does not seem like it would be very hard to implement but I am not a software engineer! The added RTK data coupled with the current ability in Drone Deploy to lock to a control point would produce a highly accurate 3D model.
Another question which maybe a feature request is… Currently we can lock our drone data to a known control point. Is the system limited to one control point or can multiple control points be specified? Realistically you need four or more control points in order to lock down all axis of your data.
Sorry for the long post. Please share your thoughts and correct me if I have misspoken!
