To get some idea of gps accuracy to the following:
- select a stationary landmark you can find easily.
- Store this landmark's location several times waiting for example few
hours between the measurements. I make ususally about 20 measurements
within few days.
- After storing all the measurements use LS show area feature to find the
approximate center point of these measurements. This could be done for
example counting how many measuremest are to north from some of the
refrence point and how many are south. If there are more measured points
at north move virtually to the nearest point northward until there is
approximately equal number of points at each side. Repeat this procedure
- After finding the central point you can look for radius where 90
percent of the points will fit. This should give you quite good
estimation what kind of accuracy you can expect.
To compare different receivers repeat the measurement phase for every
receiver and look for new center point.
