Curious about this application: deploying Reach M+ on a moored buoy with solar panel and battery pack to monitor water surface elevations in a remote reservoir, PPK correcting observations with nearby CORS stations. M+ would be in a protective case with vent for cooling with antenna on top of buoy. Could the M+ reliably collect a month’s worth of observations at a time? Would M+ be sufficient (CORS station is 11km away) or M2 better?
