Remote command-and-control of drone operations depends fundamentally on the communications infrastructure connecting the operations centre to the mission area. The security, reliability, and performance of these links are not secondary concerns—they are foundational requirements that constrain the entire operational envelope.
Threat landscape
Communications links for remote drone operations face several categories of risk. Interception of command or telemetry data could compromise operational security. Interference or jamming could disrupt mission execution. Spoofing could introduce false commands or data. And simple link failure—due to infrastructure damage, atmospheric conditions, or congestion—could isolate the remote operator from the aircraft.
Addressing these risks requires a layered approach: encryption for data protection, authentication for command integrity, redundant pathways for availability, and degraded-mode procedures for resilience.
Encryption and authentication
All command-and-control communications should be encrypted to prevent interception and protect the confidentiality of operational data. Authentication mechanisms ensure that commands originate from authorised sources and that telemetry data has not been tampered with in transit.
The specific encryption standards and authentication protocols will vary depending on the operational context and the applicable security requirements. For civilian operations, industry-standard encryption may be sufficient. For dual-use or security-sensitive contexts, additional measures may be required.
Redundancy and fallback
Single points of failure in the communications architecture create unacceptable risk for high-consequence operations. Redundant communications pathways—using different technologies, frequencies, or routing—ensure that the loss of one link does not terminate the mission.
Fallback procedures define what happens when all communications are lost. These procedures are defined in advance, tested, and documented as part of the operational governance framework. They represent the outer boundary of the operational envelope: the point at which the system falls back to pre-programmed safe behaviour.
Audit logging
All commands, status changes, and communications events should be logged for post-event review. This audit trail supports incident investigation, regulatory compliance, and operational improvement. In security-sensitive contexts, the integrity of the audit log itself must be protected.
