I find myself often photographing archaeological digs or while walking in cities. I am looking for a solution to log coordinates for every position where I take a photograph (with a Nikon Z7II). Ideally, these coordinates should be 10 cm (or better) accurate when I photograph in situations without severe multipath effects).
I think that the M2 or M+ would be useful to me, but I understand that I also would need an adaptor to connect the M2/M+ to the hot shoe. Does this work with every camera hot shoe (so any of my Nikon D-SLRs and mirrorless cameras)?
Would I also need an antenna for this solution? Ideally, all should fit on top of my camera or on a cage I built around it. What antenna would you advise? Would the Tallysman GNSS antenna work for my purpose or would I need the Multi-band GNSS antenna? What would be the difference between them?
Finally, can I connect the M+/M2 to my phone over WLAN to get the RTK correction signal? I am living in Vienna, and I have free access to the EPOSA correction signal. If not, how would I otherwise get an RTK correction (PPK is too cumbersome for me and when I walk around, it is impossible for me to set up a base station)?
With RTK correction coming over my phone, is there any reason to use the M2 over the M+?
Sorry for all the questions. I appreciate any help or insights!
