- 1.
What is the primary function of an antenna in GNSS?
Hint
Think about what is needed to receive satellite data well.
- 2.
Why are antennas often mounted on tripods?
Hint
How can we enhance signal reception?
- 3.
What is the role of an antenna in GNSS?
- To process data
- To capture satellite signals
- To transmit signals
Hint
Consider whether the antenna inputs or outputs signals.
- 4.
Antennas should be placed in areas with obstructions like buildings to ensure clear signal reception.
- True
- False
Hint
Think about how obstructions affect satellite visibility.
- 5.
Consider a GNSS survey that faces weak signals due to nearby obstructions. Design a survey plan that maximizes signal quality, taking into account antenna selection and positioning.
Hint
Think about both equipment and environment for the survey.
- 6.
Discuss the implications of using a low-quality antenna for critical GNSS surveying tasks. What might occur if an important project relies on this setup?
Hint
Consider how poor initial signals lead to compounding errors in measurements.
