We recommend printing several copies of this sheet to check yourself before every flight.
| BATTERIES | BASE STATION |
| All batteries and the RC charged to 95-100% | BATTERIES |
| No damage, battery contacts clean and intact | No more than 10 km from the flight area |
| Batteries warmed up if air t ≤ +5⁰C | Leveled on the pole/tripod |
| QUADCOPTER | Normal GNSS signal reception |
| Propellers: no cracks, kinks or chips | Switched on before the first flight |
| Motors spin freely | Switched off after the flights |
| Helix antenna installed | Output file format: RINEX |
| Gimbal clamp removed before power-on | For a reference station: RINEX version 3.02 |
| Lens clean and intact | High-precision APC coordinates determined |
| VPS lenses cleaned of dust and fingerprints | GROUND CONTROL POINTS (GCP) |
| Nothing obstructs gimbal rotation | Placed BEFORE the flights |
| Memory cards cleared | At least 3 GCPs per route |
| ROUTES | Targets sized for the image GSD |
| GSD and altitude determined in advance | Targets have a contrasting color |
| Routes planned in advance | GCP centers surveyed |
| If elevation difference ≥ 20 m – terrain following | Pole height and BS APC height entered |
| 1 route = 1 battery | Survey points with a level |
| Check speed and altitudes before take-off | CAMERA SETTINGS |
| Check route parameters before take-off | Focus on the ground from working altitude AF->MF |
| Completion action: return to home | Shutter from 1/2000 to 1/640 - OK |
| Routes uploaded to Litchi | ISO 100-200 OK (400 undesirable) |
| BEFORE TAKE-OFF | Aperture fixed at F 2.8, does not change |
| Calibrate the compass! | Motion blur from shutter speed ≤ 1 GSD |
| Take-off site level, clean, no metal | Check photo quality on the ground |
| Choose a higher spot for the pilot | Do not use autofocus on the route |
| Make sure there are no obstacles above | Monitor photo parameters in flight! |
| Flight altitude above obstacle height | Check that recording to the memory card is on |
| You are aware of all possible risks | Check the 3:2 aspect ratio |
| WEATHER CONDITIONS | AFTER LANDING |
| Wind: no more than 10 m/s | Switch the drone off, then start packing |
| Temperature from -20⁰C to +40⁰C | Charge all batteries to 100% (can be later) |
| Good visibility: no fog or haze | Clean and wipe the Air 2S if needed |
| No precipitation: snow, rain, frost, hail | Put on the gimbal clamp when moving |
| No magnetic storm above level 5 of 8 | Replace the drone memory card with an empty one |
