Advances in satellite technologies have made space-based communication a fundamental part of life. Nonetheless, the primary communication satellites used by the United States and its allies will soon need replacement. Though challenging, this situation presents immense opportunities.
New systems could provide long-needed interoperability among U.S. military branches and allied forces. High-capacity satellite crosslinks could reduce the need for costly and potentially vulnerable ground-relay stations. Powerful computers could process data onboard satellites for more flexible routing and packet switching.
On the other hand, such highly capable systems carry a high price tag. Although the procurement community has been exploring streamlined acquisition methods and cost-sharing initiatives, recent events in the civil and commercial sector warn against excessive reliance on private industry.

Aerospace has made major contributions to the field of satellite communications and continues to develop cost-effective solutions to tomorrow's problems. Research into more efficient modulation, more reliable signal coding, and more robust antenna design has shaped the system architecture of the future. At the same time, collaboration on spectrum-management issues has helped policymakers understand and protect this vital resource.
This Crosslink provides a brief overview of The Aerospace Corporation's important work in the increasingly important field of space communications.
