NOAA SWPC Satellite Environment Testbed Exercise 2023

NOAA SWPC Satellite Environment Testbed Exercise 2023
published: Monday, April 15, 2024 13:46 UTC

Satellite orbital drag and energetic particles topped the list of space weather threats to low-Earth orbit satellites discussed at the Satellite Environment Testbed Exercise held in Boulder, Colorado this week. Space weather scientists, satellite owner-operators, tracking and maneuver service providers, and related commercial service providers gathered to better understand how satellite companies plan for and respond to space weather. During the three-day meeting, experts also assessed current space weather products and services for the satellite industry that are offered by NOAA's Space Weather Prediction Center (SWPC) and other service providers.
