The Neuron,colloquially known as "The Magic Ball",is an intelligent and versatile sensor platform that helps electric utilities make power transmission safe,reliable,affordable and sustainable. On average,the solutions from Heimdall Power increase transmission capacity of existing infrastructure by 40%,while also providing complete grid awareness. The small and powerful Iridium Certus 9704 IoT module was easily integrated into the existing robust and lightweight Neuron sensor to implement reliable connectivity,especially in areas where cellular networks cannot reach. Now utilizing the Iridium satellite network,Heimdall's Neuron sensor has turbocharged its capabilities by enabling essential real-time data transmission to and from anywhere in the world,making it a cost effective and indispensable solution for utilities worldwide.

"99% of high voltage powerlines do not have any sensors,making the power grid one of the most underutilized assets in the world," said Jørgen Festervoll,CEO,Heimdall Power. "The work we're doing with Iridium is going to change the world,because for the first time ever,we can send actionable insights from every part of the grid."

"The Iridium Certus 9704 module is uniquely suited for the Neuron sensor,allowing Heimdall Power to change the way powerlines and grids are managed on a global basis,in real time," said Iridium CEOMatt Desch. "With unmatched reliability and innovation,Iridium remains the top choice and industry leader for satellite IoT."
