Hi Ben!
Your wlcome. Glad to hear, otherwise I have to track.

I have done some more test with the GPS work nice, buuuuut when I measure the groundspeed I measure compared with my navigator in the car,
I see:


26 km/h FC9 GPS > 50 Navigator km/h
53 km/h FC9 GPS > 100 Navigator km/h
70 km/h FC9 GPS >130 Navigator km/h

Do I forget some calculation or?


Thak´s in advance

Hi!

Little progress. After I change the Return variable from Int. to Float (as the it also should be ) the speed is now more liniary. But the speed I readout is only the half, so I have to multiply with 2. Is this the way???

I perform some test today with speed up to 70 km/h and compared with my navigator almost equal.

Tomorrow (monday) I have to drive a longer trip, my job, and I make some more readout and get some more experience and you hear.

Hi again!

By multiply the readout with 2 (why this?) and compared with navigator in my car and speedometer on my phone I get.

The FC9 GPS -------------- Navigator

Km/h 108 > 100 km/h
" 130 > 120 "
" 97 > 90 "
" 86 > 80 "
Ect..

Something to do please

Hi Jorgen.

GPS returns ground speed in knots. To convert from knots to kph multiply by 1.852 and hopefully that gets you close.

Hi Ben!

ok, of course it make sense

Try tomorrow and convert, thank you Ben..
