1. 1.

   What is a GNSS receiver?

   Hint

   Think about how your phone uses GPS.

2. 2.

   How many satellites are needed to determine a GNSS receiver's position?

   Hint

   Remember the concept of triangulation.

3. 3.

   How many satellites are needed for a GNSS receiver to compute its position?

   • 2
   • 3
   • 4
   • 5

   Hint

   Think about the triangulation process.

4. 4.

   GNSS receivers can be divided into which two categories?

   • Dual-Frequency and Triple-Frequency
   • Single-Frequency and Dual-Frequency
   • Only Single-Frequency
   • Only Dual-Frequency

   Hint

   Recall the different types of receivers discussed.

5. 5.

   Describe a scenario where a dual-frequency GNSS receiver would significantly outperform a single-frequency receiver. Discuss the importance of accurate positioning in this scenario.

   Hint

   Consider high-stakes environments where exact placements are essential.

6. 6.

   Evaluate the challenges faced by GNSS receivers in dense urban environments and how dual-frequency technology might address these.

   Hint

   Think about how buildings or trees might interfere with satellite signals.
