- 40 computation cycles per second for high accuracy
- Automatic calibration
- Distance error: <5% of distance traveled
- Heading error: 3° per minute without GPS
- Compensates temperature influences
- Elimination of gyroscope aging effects

Depending on the quality of the available GPS signals,
the u-blox proprietary EKF algorithm computes the
next positions accurately by using an automatically
weighted average of the GPS and sensor inputs. The
weighting of GPS and dead reckoning is determined
by quality of GPS signals and confidence level of dead
reckoning information.
