1. The system is to have five tethered drones along the lB with distance Of 50 Km in between two tethered drones with ELINT payload. 2. The drones are to be mounted on SUV class Vehicle (Each drones on one vehicle}. The drone vehicle should have a modular storage Space {trays} for housing drone with the purpose of Storage, transportation, charging, launching and recovery. 3. The Drone/s should be stored in tray/s, which can be extended through a Suitable mechanism for launch of drone/s and the trays could be retracted after the drone/s are recovered, for changing, Storage and transportation, analysis operator consoles and data link. 4. The System inside the vehicle/s Should have compact receivers for ELINT. Suitable SAG graded encrypted SATCOM to be provided with the system to transfer data in real time to the higher echelon {e- Anveshan } on AFNET. 5. Based on the inputs received from various ESM sensors, it Should be possible to localise the position Of the adversary's EW systems in near real time (minimum latency). 6. It should be possible to deploy the system for operations from high altitude areas (up to 4 km AMSL) with UAS capable of operating up to minimum 100 m altitude from drone vehicle. Higher performance for launch and operation is desirable. 7. lt Should transmit the SIGINT data in real time to higher echelons. 8. UAS based ESM system should have sensors for ELINT and Datalink. 9. Minimum altitude of UAS above the drone vehicles is to be 100 m. Higher range performance is desirable. 10. ELINT PDWs (raw data in .csv/.xml format) from each Sensor are to be transmitted in real time to e- Anveshan server on SATCOM.
