No, kylläpä se ainakin 1/1 autossa näyttää mittarin kanssa samoja nopeuksia.........
"An update rate faster than 1Hz is not a necessity for automotive navigation, but it does have some advantages. A higher rate helps to decrease the annoying display lag time and it helps to improve tracking and distance measurements especially if one is traveling on a curvy route.
The only disadvantage is that a faster data update results in an increased computer processing load. Rates of 5-10Hz should, however, be well within the capability of current generation personal computers.
The issue of whether or not a GPS navigation program is compatible with update rates other than 1Hz depends on the synchronous or asynchronous nature of the data transfers and the software being able to adjust any time dependent measurements as is appropriate for the different sample rates. It is unknown which, if any, of the current GPS navigation programs can handle data update rates other than 1Hz."
