3. Details of OEM's with their products are depicted in "Products Category in Detail"

1.We have developed/ are developing user specific products for defence forces. One of the major product designed and under production/ supply is RESS system which is expected to prove as major force multiplier for our ships/ submarines at sea. The system involves design of high latency data network and is based on Patented Technology.

2.The RESS System aims to provide maintenance support for Embedded Systems in all modern systems of ships and submarine at sea without the need for them to return to harbour or yard for defecation. This is done using the existing satellite communication network of the Indian Navy through which specialised setup on the ships or submarines is able to communicate with complementary setup at SEGs or any other centre in yard for trials/ tuning/ defectation for direct and instant online help.

3. We are currently manufacturing 10 RESS Systems, which are planned to be delivered from Nov 22 to Jan 23.
