GPS show truck is way off freeway when it’s not

[c379776]

My GPS at times shows my truck so far off that the Navigation path that it will reroute and then the truck starts to follow the new navigation route. Of course I stop it before that happens. Service replaced the GPS antenna today no help.

Some people say the nav data comes form TomTom. I am not sure, but the nav control on my CT periodically sends me to locations without roads, "shortcuts" that are dirt and 10 miles longer, U-turns on freeways for mysterious routes, etc. I live in NV and think it might be bad location data, but not sure. Interstate freeways and direct paths between Tesla chargers seem to be ok, but not when I get outside of the "tunnel". On a micro-scale this might be related to the position of the car on certain roads. Other CT drivers have the same bad-positioning in lanes as me when on the same roads. Looking forward to the car being able to drive properly centered in the lane, as well as a reliable road map.

3 parts: Google provides display tiles (satellite imagery), Mapbox and OpenStreetMap provide the routable street graph, and Tesla’s own vision-based system supplies the centimeter-level detail that FSD needs.

I’m also in Nevada and I haven’t had any of the issues you’re describing (besides the lane centering which is a fairly common CT FSD issue). Even in the rules I’ve been rocksolid in terms of the car knowing where it is which is a GPS/GNSS issue.

The lane centering on my truck is bad too. I’m seeing a correlation with the poor gps position. If the position is a small amount to the left (for example) the truck will hug the right side of the lane and vice versa. As though it was trying to correct for the gps position which isn’t how it’s supposed to work. Lane centering should be cameras only.

Lane centering should be cameras only.

I’m pretty sure it is, which is the reason that you really only see this in CT and no other Tesla. That’s because they just don’t have as much data for calibration. Which is also why we don’t have ASS.

Mine has been off my several streets past few days now.....

Yet the on-screen shows the truck off center the same amount and direction as seen out the window. This is not a camera calibration issue.

I never said that it was. When I say “calibration” I’m talking about of the of the vision based FSD system. You’ve ignored the context.

All of the S3XY cars are fully vision based now for FSD and none of them have the problems that the CT does. That is because the CT does not have enough data to properly calibrate the system not talking about your cameras on your car.

This is a known known. There are any number of threads on the forum that you can search and see the extensive conversations that we’ve had about it.

We believe that the reason that it doesn’t center properly and that we don’t have ASS is because while they use the same code from all the other S3XY vehicles it isn’t calibrated for the dimensions, steering and other characteristics of the CT.

I had this happen once or twice but it hasn’t happened in a very long time. If I remember correctly, the solution I found online was to turn off sentry mode and walk away for a period of time, allowing the truck to auto-lock and sit for a bit. When I came back all was well. Turned sentry mode back on and proceeded as usual.

I read that the 3rd party Rearview camera/mirror wiring could affect the gps. I wonder how many of these complainers have them installed…

Sorry I don't get it. The trucks are not vision based? What are they?

They are vision based. However vision based FSD has to be trained and calibrated for the vehicle; which requires more data than Tesla has due to the limited number of cyber trucks that they have produced and sold and are on the road collecting that data for them. Unlike the rest of the S3XY vehicles.

This is why the CT has always lagged behind the other cars with what FSD capabilities it had or whether it had FSD at all. This is the exact reason we don’t have actual smart summon (ASS). So, the collective wisdom has been the reason that the cyber truck can’t lane center and all of the rest of the cars can is because they need more data to calibrate FSD for our trucks.

It isn’t one-size-fits-all. Vision based FSD yes but where are my tires at when I turned just now how much did I move over in the lane all of that must be calibrated for the cyber truck and it is entirely unique from any other car in the lineup. And the data is limited.

and now GPS is magically fixed...

I'm thinking there was a problem with the feeder file(s)...

Here I am driving 75mph on hwy 126 and the truck begins to follow the newly drawn incorrect routing.
