e-obs specialises in GPS telemetry for wild animals. Based in Grünwald, Bavaria, the company develops lightweight, solar-powered GPS tags for wild birds. As well as tracking position, integrated sensors also record data such as speed, wingbeat and flight attitude. A radio module featuring Telekom’s IoT eSIM chips connects to the mobile network several times a day to transmit the stored data to the e-obs server. The data can then be made available to the scientific community via research platforms. Thanks to Telekom’s global IoT network, the tags remain accessible at all times, even when the birds cross multiple countries and mobile networks.
