Diving data graphs and 3D maps. If you had to hide from GPS, your best bet would be underwater. The sound waves don’t just travel directly between the observation unit and sensor. 2021 IAP offerings from the Department of Electrical Engineering and Computer Science ranged from the playful to the profound. © Shb Instruments, Inc. Unfortunately, conventional GPS does not work underwater and alternatives are power-hungry. Always know your exact latitude and longitude underwater. Battery life: 40 hours in training mode (30 hours with GPS), 5 days with 24/7 tracking . Because GPS signals are not directly receivable under water, Navimate™ functions through use of a small unit that is most commonly hung from a dive boat or buoy (the “GPS gateway”). The technology, which relies on satellite-transmitted radio signals, is used in shipping, navigation, targeted advertising, and more. The GPS gateway has a floating radio antenna in order to determine its exact location, and communicates with the wrist units via its underwater transducer portion, using acoustic signals. To track undersea objects like drones or whales, researchers rely on acoustic signaling. Since its introduction in the 1970s and ’80s, GPS has changed the world. $298. “That makes it complicated to compute the location.” Accounting for reflections is an even greater challenge in shallow water — the short distance between seabed and surface means the confounding rebound signals are stronger. Research Scientist Reza Ghaffarivardavagh led the paper, along with co-authors Sayed Saad Afzal, Osvy Rodriguez, and Fadel Adib, who leads the group and is the Doherty Chair of Ocean Utilization as well as an associate professor in the MIT Media Lab and the MIT Department of Electrical Engineering and Computer Science. “Sound is power-hungry,” says Adib. Conditions aside, the tests provided a proof-of-concept in a challenging shallow-water environment.
