Influence of topography and canopy cover on argos satellite telemetry performance

open access: greenWildlife Society Bulletin, 2012
Environmental variables can affect performance of global positioning system (GPS) telemetry; however, similar assessments have not been reported for Argos satellite telemetry. We used a stratified random design and linear mixed‐effects models to evaluate

Postbreeding Movements of Frigatebirds Tracked with Satellite Telemetry [PDF]

open access: bronzeThe Condor, 2006
AbstractUsing satellite telemetry, we studied the postbreeding movements of Great (Fregata minor) and Magnificent Frigatebirds (F. magnificens) at two breeding colonies in the Indian and Atlantic Oceans. After breeding failure, 67% of the birds with satellite transmitters remained on the breeding colonies and continued to perform foraging trips similar

A simple fragmentation protocol for satellite telemetry : Transmission of large telemetry from the MIST satellite

open access: green, 2020
MIniature STudent satellite (MIST) is a project at the Royal Institute of Technology (KTH) in Stockholm where students build a satellite. The satellite will be placed into orbit around the earth carrying six experiments. One of the experiments on-board the MIST satellite will need to send larger units of data than the radio on-board can send at a time.
