QUESTION 2

If a GNSS receiver is validated for area measurement by one

member state/region in continuous measurement method

and using EGNOS corrections with 0.75 m buffer, another

MS :

a. could use the same device in continuous measurement method

with EGNOS corrections with the same buffer of 0.75 m.

b. could use the same device in both continuous and vertex

measurement method with EGNOS corrections with the same

buffer of 0.75 m

c. have to carry out the own validation protocol and to use this

buffer

QUESTION 7

155-7 November 2013

The result of a validation test for a GNSS receiver in term of

buffer tolerance is 0.71 m. During the controls, the

inspectors will use a buffer tolerance of

a. 1.50 m because the real validation result is smaller

b. 0.75 m because it’s the nearest class of buffer tolerance

c. 0.50 m for the parcels with good conditions of GNSS

measurement and 1.00 m for the parcels with difficult

conditions (trees, masks on the borders, etc.)
