To continue the discussion begun by this lesson, I would like to pose this question:
There is much discussion about reliance on GPS/GNSS and concern about security. It has become essential to a wide variety of critical functions. Backup for, or perhaps replacement of the system are contemplated. What are your thoughts on the subject?
To participate in the discussion, please go to the Lesson 10 Discussion Forum in Canvas. (That forum can be accessed at any time by going to the GEOG 862 course in Canvas and then looking inside the Lesson 10 module.)
