14.8. GNSS Positioning Techniques

Try these first

1. 1.

   What is Absolute Positioning?

   Hint

   Think about how positions are determined.

2. 2.

   Why is Differential Positioning more accurate than Absolute Positioning?

   Hint

   Consider the extra data input.

3. 3.

   What defines Absolute Positioning?

   • A method using a single receiver.
   • A method requiring multiple receivers.
   • A competitive technique.
   • A process that follows previous measurements.

   Hint

   Consider the number of receivers.

4. 4.

   True or False: RTK positioning relies on corrections from a base station.

   • True
   • False

   Hint

   Think about the setup of the system.

5. 5.

   You are tasked with surveying a remote area where base station setup is not possible. Outline a GNSS positioning technique you would choose and justify your decision.

   Hint

   Consider the need for high precision without the availability of support infrastructure.

6. 6.

   Evaluate the effectiveness of Absolute Positioning for tasks requiring high precision compared to Differential and RTK methods.

   Hint

   Think about the situations where precision matters most.
