How does Starlink perform during heavy rain or snow?

Weather Resistance

Starlink’s satellites and ground equipment are built to withstand a wide range of environmental conditions, including heavy rain and snow. The satellites themselves are designed to operate in a 3-axis stabilized configuration, allowing them to maintain their position in orbit regardless of weather conditions on the ground. Additionally, the Starlink user terminal is IP67-rated, meaning it can withstand immersion in up to 1 meter of water for 30 minutes.

Signal Loss and Latency

While Starlink’s weather resistance is a significant advantage, heavy rain and snow can still cause signal loss and increased latency. In heavy rain, signal loss can be as high as 30-40% due to water absorption in the atmosphere, which can lead to dropped connections and delayed data transmission. Snow can also cause signal loss, but to a lesser extent, typically around 10-20%. To mitigate these effects, Starlink users can consider using a signal booster or increasing the number of user terminals in use.

Mitigating Weather-Related Issues

To minimize the impact of heavy rain and snow on Starlink performance, it’s essential to take proactive measures. One technique is to position the user terminal in a location that is protected from the elements, such as a covered porch or under an awning. Another approach is to use a directional antenna to focus the signal and reduce the impact of signal loss. Additionally, users can consider using a redundant system, where multiple user terminals are set up to provide a backup in case of signal loss.
