In 1997, Microwave Telemetry, Inc. produced the industry’s first pop-up satellite tag (“single-point pop-up tag”), which transmitted geolocation and temperature data. This innovation instantly prompted new insights into fish migration and stock management.

Building on past successes and advances in microelectronics, sensors, and programming, we continue to push technological limits to enable tracking of smaller species.
