+DanAL70 Posted January 28, 2006 Share Posted January 28, 2006 (edited) Had my 60csx out today as well the best accuracy I can get is 10-12 feet. With my 60cs I had accuracy of 2-3 feet most of the time. I was just wondering perhaps that may have been a false accuracy. With the new sat. rec. perhaps this accuracy is closer even thou it is reading 10-12 feet As I said, I never got accuracy better then 12-14 feet with my 60CS, but thats in Europe - Usually you can't get EGNOS signal here (at least with Garmin). Anyway, accurancy of 2-3 feet seems wrong to me - thats 60cm accuracy! Thats much better then Garmin's specs! Batnun those 5 decimals for each degree, at the latitude of 45 degrees where I live, will provide an 1.2 meters resolution (that men 4 feet). no matter how good is the accuracy, if resolution have only 5 decimals, an 2-3 feet accuracy shown on gps is fake (unless you are close to north or south pole, but I haven't experience that). you need an extra decimal to be shown in order to have a better resolution, so only then we can talk about accuracy less then 4 feets (if that will ever happen). this is like someone have only indications for hour and minute on it's mechanical watch and is trying to figure out it's watch seconds accuracy. he will be close to...., but never sure about. I've used to see 4-5 meters (12 to 15 feet) accuracy on eTrex Legend and on GPS V. I've got 2meters (6 feet) on GPS V only when EGNOS was active. I'm taking tracks and points for RO.A.D. (garmin map of Romania, you can check www.romaniadigitala.ro, but only romanian language not english), so i've tried to get the best from my gps on the laptop placed on the right seat. filtered the track for each second, at every red-light i've got a terrible jam of the track. filtered the track for 5meters, tracks got more accurate (without garbage). ofcourse traveling high speed spots got only at 10, 15, 20 meters and so on. to have 3 to 5 meters (10 to 15 feet) accuracy is fine even for geocaching. the gain I would expect from SIRF is fast acquiring of satellites, and tracking signal in bad coverage situation. hope i'll have soon an GPSMAP60 CSX. best regards, Dan Edited January 28, 2006 by danal70 Quote Link to comment
