3.4.6.3.2. Carrier phase receivers

Try these first

1. 1.

   What is a carrier phase receiver?

   Hint

   Think about how it differs from standard GPS.

2. 2.

   What frequencies do dual-frequency receivers track?

   Hint

   Remember the specific frequency numbers.

3. 3.

   What is the primary function of a carrier phase receiver?

   • To measure time delay
   • To calculate phase differences
   • To broadcast signals

   Hint

   Think about how they identify locations.

4. 4.

   True or False: Dual-frequency receivers have lower accuracy than single-frequency receivers.

   • True
   • False

   Hint

   Reflect on their functionalities.

5. 5.

   A surveyor needs to determine a plot's boundaries but only has access to a single-frequency receiver. Discuss the potential issues that may arise due to ionospheric errors and propose a solution.

   Hint

   Consider how the error types affect long-distance determination.

6. 6.

   Explain how the phase measurements in carrier phase receivers provide advantages for relative positioning over longer distances compared to code-based methods.

   Hint

   Reflect on the accuracy needed for longer distances in surveying.
