In the aftermath of the Dantewada massacre by the Naxals, Chhattisgarh authorities have begun night trials of Unmanned Aerial Vehicles (UAV), to equip security forces with real-time information of targets. The trials held at the grounds of Counter Terrorism and Jungle Warfare College started at Kanker district on Wednesday and continued till early on Thursday morning.<br/><br/>During the trial, the security experts gauged the machine's feasibility during temperature variations, at various heights and in detection of landmines. Sources said the services of UAVs, which have been used by US forces to track down Taliban militants, are urgently required as the forces engaged in anti-naxal operations need real-time information to achieve greater success. UAVs can go up to a height of 10,000 feet, fly at a speed of 70 kilometers per hour and can provide 240 minutes of sensor imagery to the ground station. The night-long trials also saw its use in detecting people in pitch dark and dense forests.
