A satellite killer chain, also known as a kinetic kill chain, is a hypothetical scenario in which a collision between two satellites in orbit leads to a chain reaction of satellite destruction. This scenario could potentially have far-reaching impacts on global satellite-based communication systems, GPS navigation, and other space-based services.

The chain reaction could begin with a collision between two satellites in orbit. Depending on the size and speed of the satellites, the collision could produce a large number of debris pieces, ranging in size from tiny fragments to large pieces of debris. These debris pieces could then collide with other satellites, potentially leading to their destruction as well.

The effects of the satellite losses would likely be felt within a matter of days or weeks. As more satellites are destroyed, global satellite-based communication systems and GPS navigation would be disrupted, potentially causing widespread disruptions to a wide range of services and industries that rely on satellite technology.

In a worst-case scenario, the satellite killer chain could continue for an extended period of time, potentially leading to the destruction of a significant number of satellites in orbit. This could have long-term impacts on the development of space-based technologies and applications, as well as the global economy. It could also make it more difficult and costly to launch new satellites, hindering the growth of the space industry.

Recovering from a satellite killer chain would likely take several years, if not longer. In addition to the cost and difficulty of launching new satellites, cleaning up the debris left in orbit would also be a significant challenge. This could require the development of new technologies and strategies for removing debris from orbit, which could take years to implement and would likely be extremely costly.

In conclusion, a satellite killer chain could have far-reaching impacts on global satellite-based communication systems and other space-based services. While the specific effects and timeline of such an event are difficult to predict, it is clear that it could have significant short- and long-term impacts on the space industry and the global economy.
