EP is becoming the default in-space drivetrain; the PPU is its acknowledged bottleneck; the merchant supply is nine vendors, one outside the US/EU, none in India — and this team has built the hardware once already, inside ISRO.
Lightweight GaN-based EM design informed by the bench-proven silicon stage; radiation-data-backed GaN parts selection and derating; Bengaluru lab; first two engineering hires.
Vacuum load test · thermal-vac soak · EMI pre-scan · arc-survival and ignition-transient campaigns against a thruster simulator.
Thruster-coupled vacuum test with a partner thruster; IN-SPACe authorization; first LOI-to-order conversions. Exit at TRL 5–6.
No patents yet — the moat today is scarce, flight-programme-acquired design know-how: soft-switching a space-grade high-voltage stage through ignition and arcing without losing the EMI budget, now being carried into wide-bandgap GaN. Filings are planned where they protect rather than disclose; qualification evidence and customer integration depth are the compounding defenses in this market.
Market map (23 : 9 : 1 : 0), source table and heritage documentation are available in diligence. A bench demonstration of the running breadboard is available under NDA.
