Certified Direct-to-Device Satellite Professional (CDTDS-P) Certification Program by Tonex
The Certified Direct-to-Device Satellite Professional CDTDS P program equips specialists to design, deploy and secure direct satellite connectivity to everyday devices over emerging non terrestrial networks. Participants explore how 3GPP NTN standards, RF constraints, link budgets and constellation design come together to enable smartphone and IoT terminals to talk directly to space assets.
The program highlights how cybersecurity influences every layer, from waveform choices and access control to key management and over the air protection of user traffic. Learners examine threat models for direct to device services, including jamming, spoofing and protocol abuse, and learn how resilience strategies can be embedded into payloads and ground systems. By the end of the course, attendees will be ready to work across satellite and mobile teams to deliver secure, reliable and commercially viable D2D services in demanding environments.
