before u go on ranting bout GPS, do u even understand how it works ?
what type of GPS are u talking about ? aGPS ? or plain 1990's GPS ? HSGPS ?

and no, the GPS machine you have isnt accurate. whether its on a crummy i550 or N95 or garmin nuvi or tomtom or mio c230 or magellan its not accurate.
if it is, please head on over to mypdacafe.com and there'll be 1000 users waiting to buy the system from you to sell to the military. even military's high sensitivity receivers condones a .7 sec delay.

aGPS 7 HSGPS uses calculation correction methods to make it seem like its on real time but it just isnt. so u may be travelling 100km/h @ 12.09.0543am but in actual fact u're not.

like what sleepwalker has said, if u wanna know what speed u're at, on that current moment, use a speed camera. they exist for a reason.


btw there was once a court case hearing from a police officers son, who claimed the speed on his sat nav didnt tally with the speed camera captured. the judge ruled it out and arguments went on.
anyway the speed camera recorded the real deal and the judge ruled it in favor. i'll see if i can dig up that old news. it came out in the newspapers once in the star. forgot when.

and i highly agree with the words that u used. quite accurate is right.

you're welcome !

adding on...... nothing is real time ! not even calculations (based on moving vehicle because when u're stagnant why would it need to be real time anyway). if sat navs are all in real time + accuracy, our body would've been mutated by radiowaves and we'd all have cancer. i dont want cancer.
