Great stuff TK. Smokin fast as usual, well done

nice work tony k you mite as well call that 30    and quick alpha 

If we had GPS precision corrctly at 2 not three after . then rouding 29.997 possibly comes to 30 ktn TonyK. I doubt that using precision to thousands of seconds not hunders or even tens is correct. Our GPS 10Hz even corrected by Doppler are not that precise. 

I did  such experiment and type your result in excell. Bothb are same numbers . So technically you did 30 ktn. 
That should be follow be question to GPSTC why even they using such extent of precission which is not compatibile with oue GPS devices?
