GPS: Saving the World One Elephant at a Time Oct 17, 2008

Combination GPS/GSM tracking devices are more commonly associated with fleet tracking and asset management, but an elephant conservation group in Kenya is using the same technology to track elephants, and in some cases, save their lives.

In the Know Over Snow Leopards Jan 1, 2007

In a first of its kind study, a female snow leopard was fitted with a GPS collar that will provide researchers with an unprecedented amount of precise data on snow leopard movements and habitat use.

Scientists Seek Swan Song for Bird Influenza Oct 1, 2006

A 70-gram solar-powered GPS transmitter is helping scientists shed light on how wild birds spread avian influenza.

Even Small Animal H.A.B.I.T.s Now Can Be Tracked Aug 1, 2006

A technology partnership between H.A.B.I.T. Research Ltd. and u-blox will soon make it possible for scientists to study the behavior of endangered species once thought too tiny to be tracked by GPS, raising the hope that many smaller species may be saved from extinction, according to H.A.B.I.T. President Jeffrey Goodyear.

Go Deep: Marine Mammal Marker for At-Sea Monitoring A tracking tag mounted atop a seal's head rapidly sheds water when the animal surfaces so the GPS antenna has maximum exposure to the sky. The tag's sensors and electronics are potted to protect them from salt water and to withstand up to 3,000 psi pressure. Aug 1, 2006 By: Gabriel Hugh Elkaim, Eric B. Decker, Guy Oliver, Brent Wright

The observation technology used by wildlife researchers can limit their understanding of the behavior of marine mammals. Surface tracking using geolocation and Service Argos tags have shown that these mammals range much farther than previously thought. Relatively simple time/depth recorders (TDRs) show that they dive more than 1,000 meters deep and for longer than one hour. To further the understanding of these aquatic creatures, we developed a smaller and more capable tag with more sensing capabilities that can be deployed for longer durations. The MAMMARK tag, measuring 2.5 ? 4 centimeters, carries a low-power microprocessor and a set of sensors that can be multiplexed through a high-resolution analog-to-digital converter (ADC).

An Eye for Landscapes Rapid Aerial Mapping with Handheld Sensors May 1, 2006 By: Jan Skaloud, Ph.D., Julien Vallet, Kristian Keller, Grégory Veyssière, Otto Kölbl

This portable system offers fast deployment with no recalibration and maps both vertical and horizontal features while maintaining optimal flight parameters.

Drive-By DTM GPS and GSM Power Cost-Effective Terrain Modeling Apr 1, 2006 By: Adam Ciecko, Bartlomiej Oszczak, Stanislaw Oszczak

A data teletransmission system for quick and efficient creation of digital terrain models (DTMs) forms the backbone of experimental work in the transmission of differential GPS and real-time kinematic (RTK) corrections. A roving vehicle carries the system and collects data for a precise DTM.

Guided to Gather — Toy Plane Upgraded with Telemetry Feb 1, 2006 By: Vanessa Espinar, Dana Wiese

GPS/INS and infrared optical sensors propel USGS's transformation of a remote-controlled one-quarter–scale recreational aircraft into a low-cost unmanned aerial vehicle designed for environmental particulate collection.

Up Close and Grizzly GPS/Camera Collar Captures Bear Doings Feb 1, 2005 By: Andrew Hunter, Naser El-Sheimy, Gordon Stenhouse

Integrating a GPS receiver with image processing and geographic information systems (GIS) helps wildlife researchers see "the other side of the mountain."
