1) ACCURACY AND PRECISION
ACCURACY
DEFINITION: is the "ERROR" of the location estimate
depends on two factors
MEASUREMENT ACCURACY
GEOMETRIC FACTOR
DOP(Dilution Of Precision)
UERE (USER EQUIVALENT RANGE ERROR)
GDoP (GEOMETRICAL DILUTION OF PRECISION) called too GEOMETRIC FACTOR
MATHEMATICALLY
to determing the ACCURACY (sigma), we have twoways
RMSE(root mean square error)
Error Convariance Matrix
ANALYTICALLY evluation of the ACCURACY
CRB(Cramer-RAar Bound)
LOWER BOUND OF THE LOCALIZATION ACCURACY
if the measures error are: 1) UNCORRELATED 2) HAVE THE SAME ACCURACY; then
UERE (User Equivalent Range Error)
1 more item...
GDOP(Geometrical Dilution Of Precision)
1 more item...
VERTICAL ACCURACY, it exists alrady a table where we can find their approximations
HORIZONTAL ACCURACY,it exists alrady a table where we can find their approximations
CEP (Circular Error probable)
6) ROLL-OUT AND OPERATING COSTS
It serves to put a limit on the accuracy
C=I^(-1)
we get a simplify C, depends on two variables
It's the uncertainty of each pseudo-range measurement
Is the error covariance matrix normalized by the measurement error
we have a table with the all differentes values
