Context

The system is a vehicle navigation system that displays the vehicle’s position on a map. GPS data might be retrieved at an insufficient rate for smooth position updates. To compensate for this, the system uses extrapolation to determine in-between positions, which is crucial for providing a smooth and accurate representation of the vehicle’s movement on the map.

Trigger

The vehicle’s position on the map is being updated when the current position is determined by extrapolation rather than direct GPS data.

Acceptance Criteria

• Extrapolated position recalculated with frequency greater than 10Hz
• System consistently maintains position update rate higher than 10 times per second
• Update rate maintained under various driving conditions (different speeds, urban vs. rural environments)
• Transition between extrapolated positions and new GPS data is smooth with no visible jumps on the map
