(Optional) Explain the scientific and mathematical components of a GNSS.

Explanation should include various applications of the formula

d = vt

where v (velocity) is the speed of light and t (time) is the difference between signal sent and signal received.

Explanation should also include

• wavelength properties within the electromagnetic spectrum
• land-based corrections for errors.

Process/Skill Questions:

• How are the properties of light applicable to the use of a GNSS?
• How has science advanced GNSS technologies?
