01.07.2019 Flash news Glider recovery with Argos back-up tracking

Australia’s Integrated Marine Observing System (IMOS) is a national collaborative research infrastructure, supported by the Australian Government. The IMOS Ocean Gliders facility operates a fleet of autonomous underwater ocean gliders that undertake measurements from shelf and boundary currents in Australian waters. They recently recovered…

26.06.2019 Flash news Great news for Argos users, the Kinéis constellation carrying the future of Argos is under production!

Production is underway on the new constellation of 25 nanosatellites called Kinéis, with the next generation Argos instruments onboard. The new generation of the Argos system is based on greater bandwidth, improved data timeliness thanks to a shorter revisit time (5-15 minutes between satellite passes depending on latitude) and two-way…

14.06.2019 Animal tracking applications Understanding the tracking of three loggerhead turtles with ocean data

Trajectories of loggerhead turtles in the Atlantic ocean and the Mediterranean Sea have been tracked using Argos transmitters. Comparing the tracks with marine environmental data provides a better understanding of the movements of these animals. Photo courtesy of Aquarium La Rochelle SAS. 35 years of monitoring….

29.05.2019 Animal tracking applications Ocean data to better understand marine animals in their environment

Argos satellite tracking makes it possible to follow the paths of tagged animals. This tracking data is invaluable, but sometimes it raises more questions than it answers. Why is the animal making a detour – or even a loop? Does it stay here or there for feeding, or for another…

17.05.2019 Animal tracking applications Argos helps reveal that British grouse moors are dangerous grounds for hen harriers

Hen Harriers is a protected species of raptor living in Great Britain. Until recently, their behaviour and habits had been observed mostly at specific times and areas. Argos PTTs have enabled monitoring a wide variety of individuals over long periods and studying threats from recreational shooting. The historic ornithological…
