Q8 What happens when RTK is obstructed?
Vision and inertial sensing provide complementary constraints for pose estimation. Monitor duration, accumulated error and quality. Continuous output does not establish constant accuracy through every obstruction.
Q9 Can indoor, outdoor, tunnel and garage routes connect?
They can be evaluated with a fusion approach. Check lighting, texture, coordinate alignment, maps and relocalization. Extended GNSS-denied routes require quality monitoring and recovery strategies.
Q10 Can it work without a local base or public internet?
Evaluate standalone positioning, local radio or satellite corrections against the accuracy target. PPP, PPP-RTK and LEO augmentation still require compatible terminals, correction services or coverage. No local base does not mean no external service.
Q11 How long does convergence take?
Compare initial fixing, cold start and re-fixing separately. Recovery figures need a defined model, satellite conditions and correction link. They do not establish universal cold-start or instantaneous global convergence.
Q12 How do positioning and navigation accuracy differ?
Position accuracy describes estimation error. Machine navigation also includes latency, coordinates, mounting and control. Evaluate open sky, obstruction and docking, pass-spacing or boundary tasks separately.
Q13 How are interfaces integrated?
ROS/ROS2, CAN, UART, Ethernet, NMEA and SDK interfaces can be evaluated. Confirm model, firmware, messages, rates, timestamps, power and vehicle protocols. Physical connectivity and complete software integration are separate checks.
Q14 How should corrections be selected?
Compare network RTK, local bases, PPP approaches and satellite augmentation by region, accuracy, delivery link and availability. Confirm authorization, formats and loss-of-link behavior, then test in the operating area.
