SPADEX campaign would consist of two IMS class-2 class (200 kg) satellites, one would be Chaser and other being Target and both would be launched as co-passengers or auxiliary payloads.[3][4] Both spacecraft would be injected into slightly different orbits.[5]
Space Docking Experiment is currently scheduled for launch from Satish Dhawan Space Centre aboard a dedicated Polar Satellite launch Vehicle.flight by the end of 2024[6][7][8]
With preliminary studies done in 2016,[12] Space Docking Experiment was approved by the Government of India with an initial funding of ₹10 crore cleared in 2017.[13] 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.[14]
As of July 2022[update], Space Docking Experiment has been sanctioned ₹124.47 crore (equivalent to ₹132 crore or US$17 million in 2023) in funding and is aiming for launch in third quarter of 2024.
