What industrial trainings are convenient for Electronics and Instrumentation Branch?

As an integral part of my academic curriculum I got to know that I would have to apply soon for an ''industrial training" before March,2016 and I have not much idea about how to approach industries. I do not have primary sources in companies as many of them are taking people who are in "Blood relations" with their employees. However I do have my CV ready and I have research experience in non linear dynamics and optoelectronics.
I am planning to apply in DRDO and ISRO, But quiet not clear whether they can be counted as industrial training or would they fall under projects? I would also like to know where should I apply in India as an industrial trainee (list of companies) ? Moreover I am not sure how to approach them exactly as I have a small group of 4 people(everyone of them having their own potential CV and skills). Would appreciate any help as soon as possible.
