Table 3
Measurement error comparison of the first-level dynamic lever arm error compensation.
| Parameters measured by the main POS | The measurement error (RMSE) | Conventional rigid lever arm error compensation | Proposed dynamic lever arm error compensation |
| Position (m) | Latitude | 0.9377 | 0.0348 | Longitude | 2.0680 | 0.0259 | Height | 2.4657 | 0.0800 |
| Velocity (m/s) | East velocity | 0.0089 | 0.0067 | North velocity | 0.0085 | 0.0077 | Upward velocity | 0.0131 | 0.0091 |
| Attitude (°) | Heading | 0.0382 | 0.0266 | Pitch | 0.0132 | 0.0115 | Roll | 0.0034 | 0.0027 |
