Directorate of Systems Reliability and Quality (DSRQ) as a nodal agency from ISRO Headquarters continued its effort in extending technical advice and other necessary support to various ISRO/DOS centres towards ensuring reliability of space systems. A special drive to emphasise the importance of delivering defect free space systems was conducted across ISRO.

Specific in-depth reviews were conducted at both Integrated Product Assurance Board level and DSRQ level for assessing the quality of systems realised for PSLV-C20, C22, C25 and GSLV-D5 vehicles, as well as SARAL, IRNSS-1A, INSAT-3D and Mars Orbiter Mission. Frequent visits to centres for addressing the quality issues were also made during the year. The intranet page of DSRQ continued to be instrumental in sharing these review outcomes and lessons learned widely across ISRO centres.

Space activities being complex in nature, all the workforce involved should be of highly quality conscious. To reinvigorate the quality consciousness in ISRO's workforce, a 'Zero-Defect delivery programme' was vigorously followed up across ISRO. It may be noted that Chairman, ISRO initiated this programme during October 2012 from ISRO Headquarters and addressed the entire ISRO workforce through video mode. Technicians, technical assistants and engineers were made part of this programme. During the deliberations at each centre, workforce from all entities were briefed about the necessity of delivering defect free space systems besides discussing the lessons learned from previous missions. Feedback was collected and specific recommendations to achieve Zero-Defect delivery of space systems were derived out of this exercise. A consolidated executive summary was also made by DSRQ and submitted to Chairman, ISRO highlighting the future plan of action.

In the era of outsourcing, standardisation of various processes in the realisation of space systems across ISRO is very important. With the help of expert teams, DSRQ took an initiative to standardise the Printed Circuit Boards (PCB) specification, realisation and qualification processes across ISRO. Vendor identification with the standardised requirements is in progress. In continuation to this standardisation efforts, seven of the existing ISRO Reliability Standards are already revised and released with the help of inter centre expert teams and about 4000 documents of the same were published and distributed across ISRO. A few more ISRO Reliability documents are under revision.

Efforts were sowed towards establishing an effective mechanism to resolve the on-orbit anomalies in various spacecraft. As a first step, the anomalies related to 14 remote sensing spacecraft spreading over 16 years were compiled with the help of ISTRAC team and is disseminated to the System Development Agencies for necessary resolution, thereby enhancing the quality and reliability of spacecraft systems. Similar exercise has been completed for communication spacecraft as well.

Visits were also made to external industries for addressing quality related issues in PCB, mechanical
hardware as well as avionic packages. Continuous feedback was given to these industries towards improvement with effective interaction from centres.

The bi-monthly in-house magazine eNews Letter from DSRQ has completed two years and is
being well received by ISRO community. The news letter highlighted important facilities,viz., Hypersonic wind tunnel (VSSC), High Altitude Test facility (LPSC), Printed Circuit Boards for High-Reliability Applications (ISAC), Non Destructive Test facility (SDSC), Traceability system for payload mechanical parts (SAC), etc. Major quality issues in foreign launches were also highlighted.
