New Sentinels of the Seas: Satellite AIS and the Birth of Global Maritime Awareness

In New Sentinels of the Seas, intelligence veteran George Guy Thomas, author of A Silent Warrior Steps Out of the Shadows, presents the inside story of his struggles in his post-9/11 crusade for security on the seas, which led him to conceive and implement Satellite Automatic Identification System ship tracking and a concept he calls C-SIGMA (Collaboration in Space for International Global Maritime Awareness). But Thomas, a quadruple qualified (surface, air, submarine, space) retired Navy commander, warns that American ports remain vulnerable as he presses for global cooperation in patrolling the seas from space for safety and security.Thomas is nominated for the National Medal of Technology and Innovation, the nation's highest honor for technological achievement, "for overcoming severe obstacles and dramatically changing the maritime world by lifting the veil of opaqueness enshrouding the seas."
