PROGRAMMING MATTERS!. If it’s a track you want, then ignore all the other marvelous things a PSAT can be programmed to do (goes for other data types, too). The more data a tag has to transmit, the less likely you will get the amount you need.

By comparing complete geolocation datasets (i.e. 100% of data) with partial datasets (e.g. 10% of data) we found that at least 30% of data was required for reliable track reconstructions using the GPE3. Below this, differences of more than 2,000 km were observed (shown below).

Generally speaking, the longer PSATs transmit their data post-release, the more data is recovered. The reality is that researches will be faced with a spread of received data volumes for different tags (as we were, shown in the plot)

Pop-up satellite archival tags (PSATs) are great bits of kit, but not infallible. They are required to be small, work in a hostile environment and operate over a large gradient of satellite reception (highest at the poles). The result – partial datasets.
