DAUPHIN COUNTY, Pa — When there’s a solar eclipse, it’s not just about the cool visuals.

It will actually have a major impact on our technology.

CBS 21 spoke with an expert to find out how it’ll impact your tech as you’re making the trek to see the eclipse.

During the eclipse, solar power production may fall quickly, causing grid operators to draw from reserves during the eclipse’s peak.

This could put stress on the electrical transmission lines.

The eclipse also messes with the upper atmosphere, where many radio waves travel.

So, when the sun rays suddenly drop, so could the signals for radio and gps, which could spell trouble for travelers.

Program lead of Geospatial Technology at Harrisburg University, Albert Sarvis, said, “Because they’re concerned about, you know, not only navigation, but traffic and being able to tell where the traffic is, many of us use Waze now and will adjust where we’re going to go.”

As a backup, he recommends either printing out your directions or downloading them in your map app.

However, Verizon says they are confident in their 5G network.

Chris Serico, a Verizon spokesperson, stated, “In areas where people are going to populate, to gather in big groups for this event, we’re actually confident that the capacity we’ve layered into the network over the last few years will accommodate any increases in data usage.”

On the flip side, scientists are hoping the eclipse can also help us improve our technology.

Sarvis explained what they could learn, saying, “The technology to analyze what’s the difference between different frequencies and different locations of satellites, and how that’s impacted by this drop in charge in the ionosphere from the lack of sunlight.”
