Lets we also add as a comment above the name of the tag parse function a link to a doc that shows the tag message formats or if we can't put a link can add the a shortened version that explains the mesage format. This will save us time later if we need to refactor something in the functions and need to know how the incoming message looks like.

actualy instead of this lets add a device_test.go and add an actual test for G62Parse and Antratek

Suggested change

	if val, ok := data.Object["speedKmph"]; ok {
	dataParsed.Attr["speedKmph"] = fmt.Sprintf("%v", val.(float64))
	}
	if val, ok := data.Object["speedKmph"]; ok {
	dataParsed.Speed = fmt.Sprintf("%v", val.(float64))
	dataParsed.Motion = true
	}

instead of this should add it to dataParsed.Speed and then in the Parse function can change it to

if point.Motion && point.Speed == 0  {
	point.Speed = self.Speed(point.ID)
}

I don't see any code changes here.

do these new trackers actually send hdop messages?

Suggested change

	points, err = G62Parse(data)
	points, err = G62(data)

Thanks.
Last thing is to add a test for Antratek and G62 functions.
