"We have identified a software glitch as the reason for failure to accomplish the mission completely to our satisfaction. We are doing further tests and are confident of conducting a successful test soon," Pillai told media persons in Thiruvananthapuram.
The 290-km range supersonic cruise missile, developed jointly by India and Russia under a joint venture, failed to hit its intended target during tests in the Pokhran ranges in Rajasthan desert last month.
"The development of the BrahMos was a mission with complicated target engagements. Some targets were visible and some invisible," Pillai said.
"In these kind of tests, a hundred per cent success has to be ensured", Pillai, who briefed media on the second phase of expansion of BrahMos Aerospace unit in the Thiruvananthapuram, said.
