Kaushik, a member of India's last of the eight Olympic gold medal winning side in 1980 Moscow Games, will assist High Performance Director, Roelant Oltmans, who will now double up as a chief coach till a suitable replacement for Nobbs is found.
Kaushik's appointment comes barely 48 hours after Australian Nobbs was prematurely relieved of his duties by Sports Authority of India for failing to produce the desired results.
Kaushik will join the national camp at the SAI Centre in Bangalore starting July 16.
Kaushik's first assignment with the men's team will be the ninth Asia Cup to be held in Ipoh, Malaysia from August 24 to September 1, which India need to win to qualify for next year's World Cup in The Hague, Netherlands.
Reacting to his appointment, Kaushik said: "I am very happy. It's an honour for any player to coach his country, I have experience of working with different people from the coaching fraternity and will give my best."
