| Summary: | London. He has been involved in GPS hardware and systems design at NAVSYS since 1991. The NAVSYS TrackTag ® uses NAVSYS proprietary technology to dramatically reduce on-time for GPS data acquisition. This has a major effect on battery size and lifetime, permitting extremely small package archival GPS tags to be built for applications such as bird and animal tracking. The TrackTag captures raw, unprocessed GPS data in a less than 30 millisecond snapshot for download when the tag is retrieved. Typically data for 64,000 positions can be recorded. The tag provides over 2 years operation with frequent updates. The packaged weight is less than 30 grams. Great flexibility, relative to update rates, is available. The time of data measurement and temperature is recorded. Other data inputs such pressure, humidity, CO2, etc. can also be recorded from auxiliary sensors. This paper describes the TrackTag, its attributes, and presents data from recent applications. In particular, the performance of the TrackTag is illustrated with plots of an albatross’s journey of 8300 miles in three weeks in the Antarctic. Positioning under heavy canopy in the Amazon is also shown. Future applications for the US Military, Homeland Defense, etc. are covered with further TrackTag improvements under development. |
