I just received two reach RS2 units. I intend on using them in a base/rover setup to establish GCPs. I do not have a subscription to a NTRIP service, and won’t be able to get one. I do however have continuously operating reference stations nearby, I can download logs from them.
It seems to me that there are two ways I could do this. Looking for advice about which way makes more sense and is easier.
In the field I could let the base establish its own position using single, average. Then use LoRa RTK between my local base and rover and use “survey” to collect the points. Back at the office, I can use RTKpost with the CORS and my local base to get a more accurate position for the base. Then, compare the offset from the field-established “base” position and the ppk-established “base” position, and correct all my collected points with that same offset.
In the field I can just collect logs from the base and rover, use “survey” just as a way of timestamping when i’m collecting points, then use RTKpost to first establish the accurate position for my local base off of the CORS, and then secondly to establish an accurate track for my rover against my local base. Then, figure out my collected GCP locations from the rover log using the known collection times from the “survey” file.
Which one makes more sense and would be easier? I got thinking about option 1) by reading the following statement in the reach documentation (tutorials: basics: placing the base: post processed kinematics) " * After you get the coordinates you may enter them manually in Base coordinates section. Comparing PPK position to the averaged position and applying corrections to the collected data is the way to compensate the shift shown in the example on figure 2 ."
