Question

............. lies between Star Age and Satellite Age in the field of GPS.

Hint:

Radio navigation systems paved the way for today’s satellite navigation.

Answer 1

The Radio Age represents the period in the evolution of navigation and positioning where radio signals were first employed for these functions.
Following the Star Age, which relied on celestial bodies for guidance, the Radio Age introduced technologies like radio beacons and LORAN.
These innovations improved positional accuracy prior to the development of satellite systems such as GPS.
Consequently, the Radio Age serves as the technological link between the Star Age and the Satellite Age.
Thus, Radio Age is the appropriate term for the blank.
