Guys,

I would like some suggestions for a GPS module that has a
barometric altimeter
dead reckoning
>1Hz update

Does such a unit exist?

I have found units with all three features seperately.

Lots of hiking GPS feature a barometric altimeter.

There are some that have dead reckoning

Garmin 18x has 5Hz update.

I want to record position data very accurately from a GPS if possible in all three dimensions. It is for the usual job of measuring acceleration and power use in a vehicle via OBD port and combining with terrain info to model the performance characteristics of a vehicle.

Thanks for any suggestions. It might even be possible that I end up getting seperate devices, but then there are issues of whether the data is recorded synchronously.
Scott

BTW if a unit has two of the three then it would be great to know of it as well.
