Proportion of fixes with each of the six location error classes for Argos-linked ear and fur tags deployed on subadult and adult male polar bears on the sea ice or coast of Hudson Bay between 2016 and 2022. Argos locations are assigned one of six error class estimates (3, 2, 1, 0, A, B; in order of decreasing accuracy) based on the number of messages transmitted to satellites. Locations derived from ≥ 4 messages have small horizontal error (< 250 m for Class 3, 500 m for Class 2, 1500 m for Class 1, and > 1500 m for Class 0), while those derived from < 4 messages cannot be estimated
