MDDI's Response to PQ on Singapore's Space Infrastructure Security, Satellite Standards and Contingency Plans

Parliament Sitting on 26 February 2026

Question for Oral Answer

1. Dr Choo Pei Ling: To ask the Minister for Digital Development and Information (a) what measures are in place to secure Singapore’s space-based critical information infrastructure dependent on satellite and space systems; (b) whether the Government has established or plans to establish cybersecurity and resilience standards required of satellite operators; and (c) what contingency plans are in place in the event of disruptions to these satellite operators.

Answer

Today, over 99% of our internet traffic is transmitted internationally via submarine cables, and domestically via terrestrial cables and radio networks. In Singapore, specific enterprises may use satellites as a secondary channel for communications or environmental monitoring.

The impact of potential disruptions to satellite services today is therefore limited. For example, operational systems in the aviation and maritime sectors are primarily supported by terrestrial networks, with satellite communications serving as a secondary mode of communications.

As cybersecurity threats to space systems are expected to evolve, the government will work closely with the industry to enhance the security and resilience of Singapore’s space infrastructure.
