Try these first

1. 1.

   What are locational errors?

   Hint

   Think about how GPS works.

2. 2.

   Name one common cause of signal loss.

   Hint

   Consider what might block signals from satellites.

3. 3.

   What causes locational errors in hydrographic surveying?

   • Signal loss
   • Weather conditions
   • GPS drift

   Hint

   Think of challenges that GPS systems face.

4. 4.

   True or False: Real-time kinematic corrections can help reduce locational errors.

   • True
   • False

   Hint

   Recall the technologies that improve GPS accuracy.

5. 5.

   Design a set of procedures to minimize locational errors when surveying a busy harbor area known for large ships that might disrupt signals.

   Hint

   Consider the environment and equipment reliability when planning surveys.

6. 6.

   Evaluate the potential risks associated with incorrect locational data in the context of navigation safety.

   Hint

   Think about what could happen in your area if there are shifts in reliable navigation data.
