Short summary
Global satellite navigation system occultation data is one of the important sources for weather forecasting. As more and more occultation missions are launched, it's becoming really important to understand how these constellations work together. This study found that combining data from 12 constellations greatly increases time and space coverage, but some missions are still essential for observing tropical regions. These findings provide guidance for future satellite planning.
