14.7.2. Antenna

Try these first

1. 1.

   What is the primary function of an antenna in GNSS?

   Hint

   Think about what is needed to receive satellite data well.

2. 2.

   Why are antennas often mounted on tripods?

   Hint

   How can we enhance signal reception?

3. 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. 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. 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. 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.
