| S.No. | Field / Checkpoint | Reference | Status |
|---|---|---|---|
| A. DGPS SETUP | |||
| A1 | Base + rover unit + L1/L2 frequency + GLONASS / GPS / Galileo Acceptance: Multi-constellation if available | Per device spec | OK NC NA |
| A2 | Base station coordinates (known + computed) Acceptance: Verified | Per CORS / project base | OK NC NA |
| A3 | RTK mode — single base / NTRIP / CORS Acceptance: Per setup | Per project | OK NC NA |
| B. OBSERVATION DATA | |||
| B1 | Point ID + time + satellites (≥ 5 typically) + HDOP Acceptance: Per surveyor | Quality threshold | OK NC NA |
| B2 | Coordinates (E, N, Z) + accuracy estimate (cm-level typical RTK) Acceptance: Per accuracy class | Per device | OK NC NA |
| B3 | Quality flag — fixed / float / DGPS / autonomous Acceptance: Accepted only if fixed | Fixed = best | OK NC NA |
| C. POST-PROCESSING | |||
