Iridium satellites not affected by recent solar storms

Aurora activity is brighter and more vigorous during solar storms

Leading scientists’ warnings that a massive solar storm, which could adversely affect satellite communications worldwide, has had no affect on Iridium satellites.

In an email to partners, Iridium CEO, Matt Desch, said “Low-Earth orbiting (LEO) satellite systems, such as ours, are actually less susceptible to solar storms than geosynchronous (GEO) satellite systems. Solar storms generate an increase of radiation that can cause issues for satellites and even some electrical systems on Earth.  However, due to our satellites’ robust design, along with our system fault detection and mitigation processes, we have little concern over these kinds of storms. This is because of the altitude at which our satellites fly as well our continued investment in our network.”

WebTech Wireless VP of Quadrant sales, Harald Fritz, said, “We chose Iridium as that critical link when regular cellular coverage is unavailable. Iridium provides the global network coverage as well as best-in-class coverage in northern regions where we service energy, resource, and government customers”. He added that this is important to WebTech Wireless clients, because “customers usually choose this dual mode hybrid solution in mission-critical or worker-safety related applications. This means their staff must always have coverage and be in constant connectivity.”

On February 15, 2011, scientists observed solar flares emitting billions of tons of charged particles that could trigger a $2 trillion global Katrina to communications satellites, electric power grids and GPS navigation systems. It was the largest solar storm in four years. Solar particles interact with Earth’s magnetosphere.
