Pisarv’s ‘Nabhrakshak’ drones advance India’s EW Resilient drone capabilities

In an era where unmanned aerial systems (UAS) define the contours of modern conflict, from Ukraine’s battlefields to high-altitude Himalayan frontiers, India’s defence ecosystem is rapidly maturing. Indigenous innovation is playing a pivotal role, bolstered by the government’s ‘Make in India’ initiative. A notable contributor is Pisarv Innovations, an Indore-based deep-tech start-up that has successfully developed and deployed advanced drones for the Indian Army, demonstrating robust performance even under intense electronic warfare (EW) conditions.

Abhishek Mishra, Founder, CEO and CTO of Pisarv Technologies, shared details of the company’s achievements with Defence Chronicle in Indore today. The firm has calibrated and fielded multiple drone variants tailored for defence applications, including platforms capable of precision strikes with rockets or grenades from altitude. Central to their portfolio is the NabhRakshak series, engineered for high-altitude operations and exceptional resilience.

Recent joint validations with the Indian Army subjected these drones to rigorous EW trials. Tests were conducted in three progressive stages: first against a jammer gun operating in all eight modes; second, utilising a larger “Big Jammer” across all frequencies; and third, with both the Big Jammer and a dedicated drone gun activated simultaneously. Remarkably, the drones remained unjammed and unspoofed throughout. According to Mishra, the systems seamlessly transitioned to pre-fed inertial navigation system (INS) paths supported by autonomous visual guidance.

“Future efforts will focus on minimising wind-induced drift and enhancing the precision of visual guidance systems,” Mishra added. This EW-proof architecture addresses critical vulnerabilities exposed in contemporary drone warfare, where jamming and spoofing have become standard countermeasures employed by adversaries.

Pisarv’s work aligns with broader Indian Army exercises, such as those validating high-altitude drone operations in challenging terrain. By prioritising fully indigenous components and AI-driven autonomy, the company is reducing reliance on foreign technology while strengthening operational readiness along sensitive borders.

As drone swarms and counter-drone technologies proliferate globally, Pisarv Innovations exemplifies how Indian startups are translating Atmanirbhar Bharat into tangible battlefield advantages. Continued collaboration between the armed forces and innovators like Pisarv will be essential to maintaining strategic superiority in contested aerial domains.
