Telemetry means “distance measuring,” in Greek ("Why satellite tracking?" 2020).

Satellite technology allows scientists to track the position and movement of threatened and endangered animals anywhere on the planet (Hart, 2009).

Different animals require different tracking devices.]]> 2020-02-26 23:11:55 UTC https://padlet.com/emartin101/3d6awri8q14o/wish/451101323 Argos emartin101 https://padlet.com/emartin101/3d6awri8q14o/wish/451104557 Argos animal tags send information to a system of satellites in orbit. The satellites then send the location of the tag back to receivers on the Earth’s surface ("What is Satellite Telemetry?" 2018).]]> 2020-02-26 23:23:09 UTC https://padlet.com/emartin101/3d6awri8q14o/wish/451104557 GPS emartin101 https://padlet.com/emartin101/3d6awri8q14o/wish/451104669 GPS animal tags receive and collect information about the time and position of the animal from a satellite and use this information to calculate an exact location ("What is Satellite Telemetry?" 2018).]]> 2020-02-26 23:23:38 UTC https://padlet.com/emartin101/3d6awri8q14o/wish/451104669 Fighting Illegal Poaching emartin101 https://padlet.com/emartin101/3d6awri8q14o/wish/451104795 Poaching is the illegal hunting, killing or capturing of animals. People poach because animal products, such as hide, ivory, horn, teeth and bone, are sold to others who make clothes, jewelry and other materials from them ("Poaching facts for kids", 2019). Many endangered species are desirable for their parts, so scientists are securing animals with tracking collars so they can view and predict their movements (Nichols, 2018). When an animal moves strangely and shows signs that it's in danger, a poacher could be trying to hunt the animal. Scientists can investigate to make sure the animal is safe (Nichols, 2018).]]> 2020-02-26 23:24:07 UTC https://padlet.com/emartin101/3d6awri8q14o/wish/451104795 Study of Climate Change and Its Effects emartin101 https://padlet.com/emartin101/3d6awri8q14o/wish/451104827 Scientists study the movements of individual animals using satellite telemetry to understand how they adapt to the changing climate (Laidre, et al., 2018)]]> 2020-02-26 23:24:14 UTC https://padlet.com/emartin101/3d6awri8q14o/wish/451104827 Hawk Mountain Sanctuary, Kempton PA emartin101 https://padlet.com/emartin101/3d6awri8q14o/wish/451106839 Scientists and conservationists at Hawk Mountain Sanctuary use GPS tracking devices to learn more about raptor life cycles and migration. They tag black vultures by harnessing trackers that weigh 30 grams (about the mass of 12 pennies) to the vulture’s back. This process does not hurt the vulture nor make activities such as feeding, breeding, or soaring difficult. All of the trackers are charged by solar panels, which last longer than regular batteries, allowing scientists collect more long-term data ("Why satellite tracking?", 2020). ]]> 2020-02-26 23:28:32 UTC https://padlet.com/emartin101/3d6awri8q14o/wish/451106839 Pros emartin101 https://padlet.com/emartin101/3d6awri8q14o/wish/451107559

ACCURACY- Both GPS and Argos satellite tracking provide scientists with an extremely accurate location of an animal at a given point in time (Tomkiewicz, Fuller, Kie, & Bates, 2010).

RANGE- Satellite telemetry makes studying species that move large distances across international boundaries a lot easier (Gillespie, 2001)

SIZE- The biggest con to these tags is their size. Because of the power supply they use, satellite tags are heavy. If the tag is powered by a battery it may only last one year or less. Larger animals can wear a satellite tag powered by solar panels that could last the entire lifetime of the animal (Meyburg, 1999).

COST- The cost of one satellite tag is between $3,000 and $7,000 ("What is Satellite Telemetry? 2018). Because scientists need to study more than just one animal, using satellite tags is very expensive research to conduct (Tomkiewicz, Fuller, Kie, & Bates, 2010).

This allows scientists to understand where these birds migrate, what habitats they depend on, and what threats they face (Meyburg, 1999). By gathering information on the movement of raptors, scientists can better understand how to protect them ("Why satellite tracking?", 2020).]]> 2020-02-27 16:18:23 UTC https://padlet.com/emartin101/3d6awri8q14o/wish/451473380 Interactive Tracking Maps emartin101 https://padlet.com/emartin101/3d6awri8q14o/wish/451660168 Check out the interactive tracking maps to see the movement of each individual bird!]]> 2020-02-27 20:20:22 UTC https://padlet.com/emartin101/3d6awri8q14o/wish/451660168 Why It Matters emartin101 https://padlet.com/emartin101/3d6awri8q14o/wish/451726909 Studying the movement of insects like the monarch help protect this important threatened pollinator species. Many insects also carry diseases that are harmful to humans. Scientists hope to use satellite technology to stop potential outbreaks to prevent diseases from spreading (Nichols, 2018).]]> 2020-02-27 23:02:08 UTC https://padlet.com/emartin101/3d6awri8q14o/wish/451726909 Image References emartin101 https://padlet.com/emartin101/3d6awri8q14o/wish/451758434
