What the cluster adds up to.
The use of Starlink satellites as a barometer represents a creative application of existing satellite technology. By measuring the drag experienced by these satellites, researchers can derive atmospheric density data that reflects changes in solar activity. This innovative approach allows for continuous monitoring without the need for additional dedicated instruments.
The primary cost of adopting this method involves the reliance on the existing operational Starlink fleet, which already incurs expenses for satellite maintenance and operation. However, the benefits may outweigh these costs by providing critical data that can extend the operational life of satellites and improve mission planning.
The effectiveness of this method may diminish in regions with fewer satellite deployments or in times of minimal solar activity. Additionally, while the approach provides valuable density measurements, it does not directly measure atmospheric pressure, which may limit its applicability in certain scenarios.
