I am looking how the measurement are being done, in other words, for example, GPS accuracy is measured in meters or feets, but it is a project characteristic. Take a look in the App for Androids called GPS Test ( https://play.google.com/store/apps/details?id=com.chartcross.gpstest ), you will see my smartphone GPS accuracy is 2 meters.
What I need to know for the Javascript Decoder that I am developing some values and units (meters/feet) and I opened another Topics to talk about operational limits, in other words, when a sensor value is considered good, bad or out of service.
I suggestion is that these informations should be part of one of manuals.
