During orbital rendezvous, the spacecraft typically approach in same plane, and phase of orbit eventually aligns. Potential rendezvous docking missions need to be emulated tested an on-ground facility for micro-gravity research prior meeting harsh conditions space environment. For docking, velocity profile two must matched. The chaser is placed a slightly lower than target. Since all these tasks are quite complex realization very expensive, any space-related hardware or software's...
