INTA SIVA (Integrated Aerial Surveillance System) is a system developed by the National Institute of Aerospace Technology (INTA) in Spain, and consists of a UAV (unmanned aerial vehicle) and a ground control station.


In 1988, INTA (with the prospect of having to develop a national battlefield surveillance system) began R&D engineering that culminates almost 18 years later (at the end of 2006) with the delivery of four pilotless aircraft. to the Spanish Army.

The usefulness of pilotless airplanes is that no war can be won without mastery of the air. One of the missions that aviation can develop is the observation of the movements of the rival. This observation has traditionally been entrusted to fighter aviation, that is, fighter-bomber aircraft equipped with powerful cameras capable of detecting movements of opposing forces. However, this presents a clear drawback: the impossibility for a pilot to stay for long periods of time on enemy territory without running the risk of being shot down, with the consequent loss of life and equipment, but also the exhaustion of long missions. duration such as those of observation, they produce in the pilots themselves and the material. For this reason, to avoid loss of human life, and to minimize acceptable losses, the first prototypes of pilotless aircraft were developed in the late 1960s (in Israel and the United States).

Spain has developed its own consistent technology that has been the work of INTA. Spanish UAVs can stay more than 7 hours in the air, deploy more than 150 km from the take-off point and can carry different types of payload depending on the mission to be developed (night vision sensors, infrared sensors, aperture radars synthetic in development, etc). In 2013, the SIVA was equipped with an automatic landing and take-off system.

What makes SIVA a truly unique system is the ability to operate without human intervention, that is: once the mission parameters have been set, the on-board computer would carry out the mission with total independence from the human factor.

SIVA systems are also used by the Air Force since 2012 to equip the School of Unmanned Aerial Systems of the Matacán School Group.
