The MiniPAT is a pop-up archival transmitting tag (PAT tag, also known as a PSAT). It is a sophisticated combination of archival and Argos satellite technology. PAT tags are designed to track the large-scale movements and behavior of fish and other animals which do not spend enough time at the surface to allow the use of real-time Argos satellite tags. Sensor data are collected during deployment and archived in onboard memory. Then on a preset date, the tag releases from its host animal, surfaces, and uploads a summary of the archived data to Argos satellites.



  • Flexible programing allows the researcher to customize and prioritize data transmission and release parameters.
  • A complete record of depth, temperature and light-level readings are stored. Should the MiniPAT be recovered, the full archive is available for download.
  • A corrodible pin allows the release of the MiniPAT from the fish on a pre-programmed date or when certain conditions indicating the tag is no longer on the fish (premature release) are met.
  • Once released, the tag floats to the surface so data can be transmitted.
  • The pinger allows for ratio tracking recovery.
