Gyro-stabilized platforms EVT-035A and EVT-035N

They are designed to equip fixed or rotary wing military aircraft, vessels and transport of all kinds, with the ability to acquire day and night images, also incorporating automatic tracking functions, on-board recording, laser rangefinder and geo target location.

These are hardened systems designed to operate in extreme environments, equipped with visible panoramic sensors and HD spotter, infrared sensor and laser rangefinder.

With the possibility of integrating into a dissemination system, the EVT-035A and EVT-035N platforms are essential tools for surveillance and monitoring for public safety, and search and rescue missions, among others.

EVT-035A and EVT-035N

General description

The EVT-035A and EVT-035N systems were developed and built by INVAP to meet the operational requirements of the Armed and Security Forces. The platform is designed to house multiple sensors or cameras and keep them stabilized against the movement of the aircraft, the vessel underway or the moving vehicle.

The cameras that equip the platform have been selected to fulfil the operational missions of surveillance, monitoring, search and rescue at sea, fire detection and night search.

The Command and Presentation unit gives to the user the possibility to control the cameras and the platform to aim at the target, engage autotracking function, view the images and their associated data and control the on-board recording system. The combined data of the rangefinder, the GPS and the inertial unit of the system also allow estimating the georeferenced position of the target.

Optionally, the system can be integrated into a communications unit to transmit images to the ground through a secure digital link, where they can be received at an earth station, an advance operator unit or, if necessary, at both stations simultaneously.
