Have somebody information on which telemetry data suspension position (meter) is referenced ? Some cars have different values in park position from approx. -6 to -60 mm
It's the position in its range relative to the design ride height position. Note this is measured on the spring/damper axis, so motion ratio may need to be taken into account. I guess the question is what you're looking to get from the data?
all values are negative and differ large from cars, but what is zero ? Maybe the max length of the shock absorber ?
