Vayulink
An indigenously-developed Identify-Friend-or-Foe (IFF) system used by the Indian Armed Forces. The Vayulink system has been developed by Wing Commander Vishal Mishra, a helicopter pilot with the Indian Air Force (IAF and showcased by the IAF at the Aero India 2023 show in Bengaluru.
Vayulink is a data link system which connects all entities, combat and non-combat, through a single link. It enhances battlefield transparency through identification of friendly forces in a combat situation — whether airborne or on the ground — through secure, jammer-proof communication, and also arms pilots with accurate weather data before they fly. The system helps get the position of all friendly forces in a battlefield or even those in support roles. When in use in a complex combat situation, the system can help all aircraft see each other’s position and location of ground troops. It has also been inducted into the Army under the name Trishul link.
