Just for FYI: i have compared the accuracy of differrent gps receiver
and noticed there are clear differences. The used method was not very
scientific, i just stored same reference point several times at
differrent times and looked the results with Loadstone's whow area
-function. I tried to find a point as center as possible of this group
of points to have similar amount of points in east/west and north/south
from this reference point.
Receivers were Globalsat bt-359,Holux M-1000, Insmat SIRF-3 (Globalsat)
and Nokia ld-3w.
There were no majod differences between both Globalsats. Insmat mad some
more hits in the range under 5 meters from reference point but it also had
one point 21 meterf from it. Bt-359 had all it's points within 10 meters
from reference points but had slighly more error. Holux had about a third
of it's points at range of 10 - 20 meters from reference. Nokia due it's
static navigation had an error of 30 meters or more.
You can still escape from the Gates of hell: Use Linux!
