on Connecting third-party RTK base stations to DJI drones
Mini 4 Pro doesn't support network RTK at all unfortunately. Even with aftermarket PPK modules you're doing post-processing, not real-time. For real-time RTK you need one of the enterprise platforms.
on Drone mapping in challenging terrain - cliffs, canopy, and elevation change
22 GCPs on 200 acres is a lot but I totally get it on terrain like that. The elevation extremes thing is key - your vertical accuracy will be garbage if all your GCPs are at one elevation. Did you have any issues with the terrain following on the steep slopes? I've had mine try to descend into a cliff face before.
on Night flying for thermal inspections - tips and gotchas
Scout the site during daylight hours. Know every obstacle, wire, and structure. At night, your depth perception is terrible even with anti-collision lights. For solar panel thermal, fly right before sunrise for best results. The panels have cooled overnight and hot spots from defective cells show up clearly. Use the strobe plus steady illumination for anti-collision. Strobe only is disorienting.
on Flight overlap settings - am I wasting time with 80/80?
Depends on the terrain. Flat open sites? 75/65 is fine. Complex terrain with elevation changes? 80/75 minimum. Structures? 80/80 with oblique shots. There's no universal answer. Match your overlap to the complexity of the site.
