The Invisible Link: Key Spectrum Issues for Space

The radio-frequency spectrum is a finite resource whose value increases as the world’s need for “always-on” connectivity grows. This has led to fierce competition, especially in the most attractive frequency ranges, between terrestrial and space services. Decisions on spectrum use can substantially impact incumbent users, particularly space-based services such as national security communications; positioning, navigation, and timing; space traffic management; weather forecasting; climate research; and emergency response. This chapter describes the complex world of domestic and international spectrum regulation and outstanding spectrum issues facing the U.S. space enterprise, as well as decisions on key U.S. proposals and positions that lawmakers will face early in the next administration.
