4Question 4.
True or False: A mobile receiver can work accurately without a base station in Differential Positioning.
- True
- False
Show hintHide hint
Consider how positioning is affected when there’s no correction.
Question 5.
If a mobile receiver is 50 km away from a base station, how might this affect its accuracy? Discuss the implications.
Show hintHide hint
Think about the wave propagation and factors influencing the signals over long distances.
Question 6.
Propose a scenario in an urban environment where Differential Positioning could optimize surveying outcomes.
Show hintHide hint
Consider how urban infrastructure affects GNSS signals.
