Multimission concept design to service linear critical infrastructures lifecycle

Critical civil infrastructures are key to citizen's well-being. Most critical infrastructure catalogues include energy installations, water networks, transport facilities, industries and government sites [1-3]. Of these, transport, oil and gas industries or urban areas increasingly demand satellite data since the availability of metric and sub-metric missions. Linear infrastructures undergo a lifecycle requiring precise data in each phase: design, impact control, trench construction, buffer upgrade, maintenance and decommissioning. Foot patrols and aerial surveillance are conventional means to monitor the rights of way. However, competitive costs, areal coverage and revisit requirements are more competitively tackled through an array of satellite missions, both multispectral and radar. The paper accounts for the use of various satellite missions supporting oil, gas, transport and built structures for overall functioning, detection of breakages and readiness for contingency, reaction and recovery.
