How did Google hold the Wi-fi balloon above?

Google's Project Loon project will cover the Internet with 99% of the Earth area via Wi-fi waves from hot air balloons . But how does Google make its hot air balloons not explode like the hot air balloon that monitors regular weather?

According to Softpedia, thanks to the huge amount of data that Google analyzed from the hot air balloons of the US National Marine and Stabilization Commission (NOAA), it is necessary to make appropriate adjustments for these hot air balloons. .

Keith Bonawitz, a motion specialist at the Google X Lab lab, where Google conducted the most ambitious groundbreaking projects, appeared on YouTube to explain why Wi-fi hot air balloons are Google can survive on very harsh altitudes (very close to space). Keeping such a large amount of balloon is an unprecedented achievement.

The main problem that Google needs to solve is that hot air balloons use the same technology as Project Loon (like weather balloons) will continuously increase their altitude until they explode.

"The time that each weather balloon stays in the stratosphere is quite limited. Therefore, Google conducted a study of the wind movement pattern from these weather balloons."

Analyzing data predicting the airflow from NOAA's hot air balloons is the key to Google maintaining these hot air balloons. The balloon will fly at the same speed as the wind.

"We attached microphones on our hot air balloons, and they were completely quiet when flying in the stratosphere. The reason was because the wind did not affect the hot air balloons. Project Loon's hot air balloon was with us. speed with the wind ".

By analyzing the GPS data, Google can orient it appropriately for Wi-fi air balloons, helping them "surf" on the wind. Continuously moving from one position to another helps Project Loon's hot air balloon to avoid continual high altitude and explosion, helping them survive much longer than the weather-tracking hot air balloons. usually, common, normal. Google will build a perfect path, making at least one balloon in each area of ​​Project Loon.

In contrast, Google has also partnered with NOAA to share tracking data on the airflow generated by Project Loon's Wi-fi air balloons. Finally, both sides benefit: NOAA helps Google retain the hot air balloon, while Google helps NOAA make more accurate predictions.

Through this project, "we will increasingly understand the stratosphere," Bonawitz said.
