- •
We explained the current problem in describing GEO space debris environment.
- •
We presented the spatial density in the ECEF coordinate system.
- •
We presented the collision rate in the ECEF coordinate system.
- •
Spatial density is relatively higher in the geopotential wells.
- •
Collision rate varies significantly by local longitude in the GEO region.
