“Internet of Animals” Project ICARUS Resumes Tracking Wildlife Via Satellite After Years of Disruption
A groundbreaking global initiative to monitor animal movements and behaviors using satellite technology has been revived after a three-year period marked by technical challenges and geopolitical instability. Project ICARUS, envisioned as a comprehensive “internet of animals,” promises to revolutionize wildlife conservation and our understanding of ecosystems worldwide.
The project, formally known as International Cooperation for Animal Research Using Space, utilizes advanced wireless sensor technology to track individual animals across the globe. A satellite carrying an ICARUS receiver was successfully launched in late November, marking a critical step toward realizing the project’s ambitious goals.
“It’s a global collaboration of scientists trying to understand animal movements and the information from animals,” explained Martin Wikelski, director at the Germany-based Max Planck Institute of Animal Behavior and the driving force behind ICARUS, in a recent interview.
At the heart of ICARUS are miniature trackers deployed on a diverse range of species – from large mammals and sea turtles to bats and migratory birds. These devices collect vital data, including GPS location, acceleration, temperature, humidity, pressure, and altitude, providing scientists with unprecedented insights into animal behavior. The system’s unique strength lies in its ability to consolidate tracking data from numerous species across the planet, allowing researchers to observe complex interactions between animals and their environments.
“This is really grasping at the interaction of animals globally,” Wikelski stated. “It’s almost like understanding dark matter and things that couldn’t be seen and studied before.”
The path to full operational capacity has been fraught with obstacles. While initially launched in 2020 aboard a Russian launch vehicle, the project faced immediate technical disruptions. After resolving these issues, ICARUS became operational in 2022, only to be hampered again by the war in Ukraine, which disrupted data transmission. Now, with the new receiver in orbit, a three-month testing phase will precede the resumption of data collection from trackers on Earth.
The potential applications of this technology are vast. Scientists envision using ICARUS to detect and respond to emerging wildlife diseases. For example, sensors could identify unusual temperature spikes in duck populations, prompting investigations into potential viral outbreaks. Similarly, unexplained mortality events, such as those affecting pelicans, could be rapidly investigated for avian influenza.
The project has already demonstrated tangible conservation benefits. In South Africa’s Kruger National Park, ICARUS trackers have aided in the protection of endangered African wild dogs, alerting rangers to the presence of animals caught in poaching snares. “With this system, we saved more than 10-15% of the population over the past few years,” Wikelski reported.
The ICARUS receiver, measuring just 10x10x10 cm and weighing approximately 1 kg, represents a significant technological achievement. However, the project’s success also hinges on fostering collaboration among scientists. Initially, some researchers were hesitant to share their data as part of a global network. Over time, however, the urgency of the biodiversity crisis has encouraged greater cooperation.
“There’s life disappearing from our planet,” Wikelski emphasized. “All these mobile species that move between countries and continents, we don’t know where they disappear. So it’s crucial we understand what’s happening so that it’s easy to remedy them.”
As ICARUS enters its next phase, it promises to unlock a new era of understanding in the field of wildlife conservation, offering a powerful tool to protect the planet’s most vulnerable species.
