Fleet Space Technologies

Adelaide, Australia commercial

Fleet Space Technologies, founded in 2015 and headquartered in Adelaide, South Australia, operates a nanosatellite constellation providing two distinct service lines: global IoT connectivity for industrial remote asset monitoring, and satellite-enabled geophysical mineral exploration using ambient noise seismic tomography — a combination that positions Fleet as a mining industry solutions company with space infrastructure at its core. Fleet's IoT connectivity service uses a constellation of small LEO satellites to provide two-way data communication for remote sensors in mining operations, agriculture, oil and gas, and maritime logistics where terrestrial cellular coverage is unavailable. Mining applications include drill hole sensor data transmission, water monitoring in pit dewatering systems, vehicle and equipment tracking in remote open-cut mines, and environmental compliance monitoring across expansive mine sites. Fleet's ExoSphere geophysical mineral exploration platform is its most technically distinctive offering: a system where arrays of seismic nodes are deployed across a mineral exploration license area, generating ambient seismic noise (from ocean waves, wind, and industrial activity) that propagates through the Earth's crust. Fleet's satellites enable real-time data aggregation from these distributed node arrays, and machine learning algorithms process the seismic data to reconstruct 3D images of subsurface geological structures to depths of 2+ kilometers — revealing the density, lithology, and structural geology signatures associated with mineral deposits. This approach provides exploration intelligence comparable to expensive active seismic surveys at fraction of the cost and without explosive sources. Fleet has attracted significant investment from mining majors interested in exploration technology and IoT services, raising over A$100 million in funding. The company competes with Myriota (IoT), Sateliot, and terrestrial geophysical survey companies like CGG and TGS in their respective markets, with the unique integration of both creating defensible differentiation in the mining industry value chain.
