Research overview: space-based wildlife tracking prospects

Initiatives to receive signals from very small animal tags via satellites or the International Space Station, such as the ICARUS effort, promise to shrink trackers and broaden which species can be followed globally. This overview considers how space-based reception could lower tag mass and power needs, enabling tracking of smaller felids and the dispersing juveniles that conventional collars often cannot accommodate. Benefits include near-global coverage in remote regions where ground stations and cellular networks are absent, aiding transboundary conservation of cats like snow leopards. The overview also notes the technical and operational hurdles that have slowed deployment. The broader vision is an Internet of Animals in which dense, planet-wide movement data illuminate ecology and environmental change.
