London Economics again recognizes Satelles STL as a viable timing solution for critical infrastructure in recently published study “Denmark’s Vulnerability To a Loss of Satellite-based PNT,” commissioned by Denmark’s Inter-Ministerial Space Committee. The study objective was to perform an overarching risk assessment, supported by several case studies with specific focus on the consequences associated with loss of space-based PNT services within the domains of the ministries represented in the Inter-Ministerial Space Committee.

Specifically, Satelles STL was highlighted as a solution for timing and synchronization users who currently rely on GNSS for critical infrastructure timing and synchronization. Because GNSS signal is subject to multiple threats and potential failures, timing users are recommended to access precise time from three sources whose delivery mechanisms are vulnerable to mutually exclusive threats. GNSS will always remain as one of those sources and Satelles STL is featured as a secondary source candidate due to the fact STL signal strength (from LEO satellites) is 300-2,400 times that of GNSS, making the signal very difficult to jam or spoof. Additionally, STL signal is encrypted making it nearly impossible to spoof. The study goes on to state LEO satellites are better shielded than GNSS satellites, from solar radiation due to the Earth’s magnetic field. And, best yet – STL-enabled timing servers are available on the market today and can operate anywhere in the world. Direct link to study (English language begins on pg. 17)
