During their initial days when infrastructure was not available they have made use of cycles to ferry their rockets. They converted a church into control room, the bishop’s house as office, a bicycle to ferry rockets and naked eyes to track the smoke plume at Thumba in Kerala. They even converted a Toilet into a data receiving centre for their first satellite aryabhata at Bangalore.
The Indian space odyssey has come a long way to launching lunar probes, working on a mars mission and ferrying foreign satellites up for a fee. Today they have successfully launched their 100th mission.
I am extremely proud to have designed some of their outsourced onboard double layered PCB's(between 92-94) for ISTRAC, SAC and VSSC.
That's an arduous journey, ISRO. Two thumbs up to your space odyssey and Congratulations on the milestone.
