ESEN Land-based Wide Area Surveillance System (LWAS), which is a wide-area motion imagery (WAMI) solution, provides persistent overall surveillance from fixed ground platforms.

ESEN Mini Wide Area Surveillance System (MWAS), which is a wide-area motion imagery (WAMI) solution, provides persistent surveillance from aerial platforms such as Class I to Class II unmanned aerial vehicles and tethered drones. MWAS system is designed with consideration of optimizing size, weight, and power requirements.

ESEN Airborne Wide Area Surveillance System (AWAS), which is a wide-area motion imagery (WAMI) solution, provides persistent surveillance from aerial platforms. AWAS system is designed to be integrated into manned surveillance aircraft and unmanned aerial vehicles (UAVs) in Class III (MALE/HALE).

ESEN Aerostat Wide Area Surveillance System (AeroWAS), which is a wide-area motion imagery (WAMI) solution, provides persistent surveillance from aerostat platforms.

GöKHUN is the ideal UAS solution for tactical multi-mission land and ship-based operations, providing the optimum payload & endurance capacity in its class.

ESEN Mini UAS is a man-portable UAS for tactical intelligence, surveillance, and reconnaissance operations.

GöRDES Vision-Based Navigation Product provides accurate and real-time position, velocity and attitude information for aerial vehicles under GNSS denied conditions via onboard imaging and image processing.

HFDF is the tactical High-Frequency Direction Finding and Monitoring System. It provides Electronic Support Measures (ESM) for communication systems in HF Band.

Airborne COMINT system covering HF, VHF, UHF frequency bands.

ESEN TACOS System combines ‘Traffic Collision Avoidance System’ (TCAS II) and Terrain Awareness and Warning System (TAWS) in a modular open architecture.

PORTIA Big Data Fusion and Analysis System enables data fusion and analysis on structured databases and unstructured open source data.

WISE23 Mission Management System provides the user with much more comprehensive and meaningful mission management support than traditional systems thanks to its artificial intelligence support and multi-sensor fusion capability.

ESEN provides modernization, updating, function enhancement, special mission conversion, system integration, and airworthiness certification consultancy services to military and civil aircraft, independently from original equipment manufacturers (OEMs), in accordance with EASA/FAA standards.

Quick Deployable, Cost Effective ISR Missions

GoKHUN fixed-wing vertical take-off and landing (VTOL) UAV system, has optimum payload - endurance capacity in its class. GoKHUN is designed to perform intelligence, reconnaissance, and surveillance missions can stay in the air at medium altitudes for a long time, and has ease of maintenance & operation and mobile operation capability. GoKHUN UAV is the ideal unmanned aerial vehicle solution that can operate without the need for a runway thanks to its vertical take-off/landing feature and can be used on both land and sea platforms.

GOKHUN UAS System, which can operate without needing a runway and is in the Small UAV category (NATO Class-I) with its weight criteria; It has Tactical UAV (NATO Class-II) class capabilities with its endurance, altitude, and range, and offers the flexibility to perform a wide range of different tasks with its ability to carry two different payloads at the same time. In addition to military and law enforcement applications, it can be used for operations as such environment (environmental pollution detection, forest fire detection, construction/infrastructure control, precision agriculture, etc.), disasters, and emergencies (earthquake casualty removal and evacuation, search and rescue, etc.), communication (telecommunication relay, mobile phone relay, wireless coverage, etc.) monitoring (fishing monitoring, power line monitoring, road traffic monitoring, etc.) and security (maritime patrol, border security, community activities, and events monitoring, drug traffic monitoring, vehicle, and personnel tracking, detection/tracking of smuggling and migration activities etc.).
