Ed50 ed87 euref92

Question 68-8 : Global navigation satellite system gnssgps what is the minimum number of gnssgps satellites required to obtain an accurate 2d position fix ?

3.

exemple 96: 3
2. 4. 5.

Question 68-9 : Global navigation satellite system gnssgps what are the effects if any of shadowing by parts of the aircraft eg airborne camera on the reception of signals from gnssgps satellites ?

It may prevent the reception of signals.

exemple 100: It may prevent the reception of signals
It has no influence because high frequency signals are unaffected. the signals will be distorted, however the error can be corrected for using an algorithm and information from unaffected signals. it causes multipath propagation.
