dunefreak Posted December 11, 2006 Posted December 11, 2006 If memory serves me right GPS with enough sattellites doin the reception thing will track altitude as well and i believe it has a algorithm built into the gps to figure out speed traveling vertical as well. Dont quote me though... But im pretty sure it can.. Thats why you need 3+ sattelites connected to get a decent reading.. Here he goes again with the whole "if memory serves me right..." schpeel :jester: come on! Quote
chuckharrisjr Posted December 11, 2006 Posted December 11, 2006 Dude we do 83 kph in our heavy a$$ car up comp!!!!! :jester: Quote
dunefreak Posted December 11, 2006 Posted December 11, 2006 Dude we do 83 kph in our heavy a$$ car up comp!!!!! KPH? Quote
chuckharrisjr Posted December 11, 2006 Posted December 11, 2006 KPH? Whats the difference? I thought when I change it to kph it was just getting more power... jk Quote
dunefreak Posted December 11, 2006 Posted December 11, 2006 Whats the difference? I thought when I change it to kph it was just getting more power... jk yeah, don't you know that when you hit that button it converts your car to "Glamis horsepower"? 400 HP at Dumont? hit that button and now you can go talk chit with the rest of em with 750 HP at Glamis.

EY3BA11 Posted December 11, 2006 Posted December 11, 2006 Velocity measured by a GPS is inherently 3 dimension, but consumer GPS receivers only report 2D (horizontal) speed on their readout. Garmin's specifications quote 0.1mph accuracy but due to signal degredation problems noted above, perhaps 0.5mph accuracy in typical automobile applications would be what you can count on. Quote
EY3BA11 Posted December 11, 2006 Posted December 11, 2006 so i was half right and half wrong... the gps can do it 3 dimensional but it only DISPLAYS the horizontal speed.. Ohh well.. Quote
OGP Posted December 11, 2006 Author Posted December 11, 2006 so i was half right and half wrong... the gps can do it 3 dimensional but it only DISPLAYS the horizontal speed.. Ohh well.. iF YOUR gps HAS WAAS, It will read vertical speed also. waas involves 3 sattelights and also up to 25 ground radar units. Quote
EY3BA11 Posted December 11, 2006 Posted December 11, 2006 yes waas will do that but its not a very common option on handheld units. Quote
SandBox_Kid Posted December 11, 2006 Posted December 11, 2006 My gps showed my top speed, on a trip from Vegas to LA, was 163 mph! I knew the diablosport tuner was good, but not that good. So, why the discrepency? Quote
EY3BA11 Posted December 11, 2006 Posted December 11, 2006 the 2 dimensional reporting of the gps.. you must have been going down one helluva steep hill LOL Quote
SandBox_Kid Posted December 11, 2006 Posted December 11, 2006 the 2 dimensional reporting of the gps.. you must have been going down one helluva steep hill LOL ....Cajon? I think it was a burp.....according to what OGP said and what Garmin says... The eTrex Legend C is WAAS-enabled Quote
painterjoe Posted December 11, 2006 Posted December 11, 2006 How accurate is GPS? Is radar more accurate? Quote
lvnalolife Posted December 12, 2006 Posted December 12, 2006 How accurate is GPS? Is radar more accurate? GPS is accurate on somewhat flat ground but for all out speed I think the radar gun would be more accurate as long as it was calibrated correctly. Quote
dunefreak Posted January 9, 2007 Posted January 9, 2007 ^^ that's fuggin funny :mc_smiley: ...so true too! Quote
