to mature technologies related to orbital
rendezvous,
docking,
formation flying
Formation flying is the flight of multiple objects in coordination.
Introduction
Formation flight in aviation originated in World War I when fighter aircraft were assigned to escort reconnaissance aircraft. It was found that pairs of aircraft ...
, with scope of applications in human spaceflight, in-space satellite servicing and other proximity operations.
SPADEX campaign would consist of two
IMS class (200 kg) satellites, one would be Chaser and other being Target and both would be launched as co-passengers or auxiliary payloads.
Both spacecraft would be injected into slightly different orbits.
Space Docking Experiment is currently scheduled for launch from

.
Objectives
* Autonomous rendezvous and docking
* Controlling one spacecraft with Attitude Control System of other spacecraft while in docked configuration.
* Formation flying
* Remote robotic arm operations
Status
With preliminary studies done in 2016,
Space Docking Experiment was approved by Government of India with initial funding of ₹10 crore cleared in 2017.
In June 2019, ISRO was looking for proposals to study remote robotic arm operation, rendezvous and docking related technologies on its PSLV fourth stage (PS4) orbital platform.
, Space docking Experiment has been sanctioned in funding and is aiming for launch in third quarter of 2024.
