- Users cannot start Work Plans under tree canopies or eaves.
- Work Plans drift off course, causing the unit to hit objects like flowerbeds outside the intended boundary.
- Users cannot successfully map their yard, resulting in a poor user experience.
- Multipath effects: GPS signals bounce off objects, causing position jumps.
- Incomplete sensor fusion: Current algorithm primarily uses IMU heading without fully leveraging other sensor data.
- RTK signal blockage or interference: Poor satellite correction signal quality.
- Dead Reckoning (DR) Algorithm Upgrade: Combines IMU and odometry to achieve ~1% precision (1m error over 100m).
- Confidence Metrics: Uses RTK status and sensor-based confidence indicators to ensure reliability.
- Strict RTK Protection: Filters multipath reflection signals and blocks false RTK states.
- Visual Odometry (VO): Scheduled for September release to detect slippage and further enhance positioning.
A stricter RTK defense strategy has already been implemented. The new DR algorithm is undergoing PPP user testing and, pending stable results, is planned for wider release in August. The algorithm allows users to set how far the system can travel when RTK is unavailable via the App.
