Offsetting position
Quote from Fred_Moto25 on 06.01.2025, 10:04Hello Guido,
I noticed that in latest version 4.09 the information is too late, consequently I missed the exit roads several times, not able to operate the move on time securely.
After seen deeper, my position on the map appears to be far below my actual position in the real world, for around 100/150 m at 90 km/h : when actually passing under a bridge, it takes additional time to pass it on the map.
To my understanding and usage in the car, it shall be reverse : first see before happening things on the map, and then you're prepared to execute your move in the real world.
So my question to you : Could it be possible to add a fine tuning of the position offset (in time or lenght) to adjust it ?
Thanks in advance for your understanding and answer

May be it could be the reason. I was reading the article about Magnetic North Pole shifted this year
"The magnetic North Pole has officially shifted position, continuing its movement away from Canada and towards Siberia. The event has prompted a recalibration of navigation systems used in ships, airplanes, and other technologies.
This point on Earth, where the magnetic field points vertically downwards, is constantly changing due to the dynamic movement of iron and nickel within our planet's core. Experts around the world collaborate every five years to update the World Magnetic Model (or WMM), a crucial tool that maps this shifting magnetic landscape. Historically, the magnetic North Pole has drifted slowly around Canada since the 1500s, but recent decades have seen an unprecedented acceleration towards Siberia, followed by a sudden deceleration in the past five years.This unusual behavior is attributed to the influence of two large magnetic lobes beneath Canada and Siberia. The latest WMM, released in 2025, provides a more precise map of magnetic north, including a higher resolution version with ten times greater detail than previous models. This improved accuracy is vital for navigation.For instance, a journey from South Africa to the UK using the old WMM could result in a 150 km deviation. While mapping and logistics companies, governments, and agencies will actively incorporate these updates, consumers won't need to manually adjust their phones or satellite navigation, as the changes will be implemented automatically. Since its discovery in 1831, tracking the magnetic North Pole has become increasingly important for understanding our planet's dynamic magnetic field."Source: https://www.usatoday.com/story/news/world/2024/11/19/earth-magnetic-north-pole-moving/76435609007/

I'm aware of this problem and working on a solution.
@blackhawk1618.... although interesting, I don't believe this is the reason for the position delay in Scenic. I suspect I need to optimise the code that runs every time a GPS position is received. It seems that currently this takes too much performance / time, causing a delay in the screen update.

Right, code performance could be a root cause, but also lag in reception and also our own reaction time from reading to ackonwledging ; even with the best ever system, when the position is sent, it would always be shown/felt too late
To me what matters ultimately is the user feeling that the system is "right"; that's why it could be only offsetting position, being put on the map a little ahead of our real position (so you arrive on the exit on the gps map before it actually occurs)
I noticed that at zero speed in a crossing the position is accurate, and it degrades according to speed increase; maybe an offset to the movement direction calculated by y= function(speed ) could work...

ich weiß nicht, ob es hier hin passt. Mir ist in den letzten Versionen aufgefallen (zuletzt 4.11(4)), dass meine GPS Ortung einige Meter ungenau ist (meist rechts der Strecke). Während einer aktiven Navigation scheint Scenic dies auf die Route zu rechnen, so dass es nur begrenzt auffällt. Problematisch wird es, wenn Scenic mich auf einer falschen Straße vermutet und die Strecke ständig neu berechnet, aber dabei nicht die richtige Position findet. Ist mir nach einer Auffahrt auf eine Autobahn passiert und war nur mit einem Neustart zu lösen.

Where is 4.11 version I didn't receive the update yet.

In 4.11 beta there is a new setting in fine tuning “extrapolate position“ try turning this off if it’s on (or on if it’s off). Maybe that will improve things.
