	=== <u>Limitations</u> ===		=== <u>Key Performance Indicators (based on performed tests)</u> ===
			* '''GNSS denied operation (1 km)'''
			** When driving 1 km without a GNSS signal (including 15–20 turns), the positional error is ≤ 25 m, achieved in at least 8 out of 10 field tests.<br>
			** Dead Reckoning continues operating beyond 1 km; however, positional error may increase after this threshold.<br>

			* '''Recovery after DR Standby (Sleep Mode)'''
			** After exiting DR Standby (Sleep Mode), the system correctly reconstructs the driven route for up to 5 minutes or 1000 m, with a positional error of ≤ 50 m, achieved in at least 8 out of 10 field tests.<br>

			* '''Real world driving variability'''
			** Real world driving conditions may vary and can impact performance results.

			=== <u>Limitations, Edge Cases & Additional Notes</u> ===
	There are some important things to keep in mind when using the Dead Reckoning functionality. The algorithm tries to correct for these issues, but sometimes they can still affect how well Dead Reckoning works.		There are some important things to keep in mind when using the Dead Reckoning functionality. The algorithm tries to correct for these issues, but sometimes they can still affect how well Dead Reckoning works.
			* '''Loss of alignment during drifting''' – Dead Reckoning alignment will be lost during drifting, when the actual movement vector does not correspond to the vehicle heading. Re‑alignment is required.
			* '''Overshooting''' - May occur when the vehicle travels straight for more than 50 m at speeds below 20 km/h. In such cases, positional overshoot may be observed. An example is shown in the attached image.
			[[File:Dead Reckoning - Overshooting.png\|300px\|link=Special:Redirect/file/Dead Reckoning - Overshooting.png]]
	* '''Position accuracy may decrease''' - If the device cannot receive a GNSS signal for a long time, the estimated position may become less accurate. This is because the sensors inside the device can only estimate the position for a limited time without help from GNSS.		* '''Position accuracy may decrease''' - If the device cannot receive a GNSS signal for a long time, the estimated position may become less accurate.

	For example: If a courier spends up to 30 minutes unloading in the underground car park, DR will remain accurate. Otherwise, positioning information will become less accurate.
