Abstract

Methods to calculate an animal’s position from light-level data collected by archival tags (geolocation by light levels) have been employed by wildlife researchers and the engineers who design the tags for over a decade. The problem of estimating longitude proved easy to solve, but accurate latitude estimates remain elusive. This paper addresses the absolute accuracy in estimating latitude (as defined by physical constraints) that is achievable using the astronomical equations and offers a new approach to minimize the variability of latitude estimations.
