Four core technology pillars — each backed by LTspice simulation data and a physical test case in the Master Test Plan.
On a tumbling satellite rotating at 1–5 rpm, solar panel irradiance changes 10× faster than conventional P&O MPPT can track. The algorithm chases a moving target and persistently loses power. Our architecture knows where the MPP is moving before the current changes — because the IMU tells it the satellite is rotating.
Orbital AI inference processors consume 50–150W at 1V core voltage. No existing space power module delivers 100A at 1V from a 28V bus efficiently. Power-Link is built specifically for this application.
A Single Event Latch-up (SEL) in a CMOS payload device can inject 10A+ currents in under 100ns. Conventional PTC resettable fuses respond in 10ms–100ms — the surge has already propagated by then. The TPS2596 eFuse responds in 400ns — three orders of magnitude faster.
The complete supervisory stack — Kalman filter, MPC, telemetry, and fault management — executes within 6,400 clock cycles per 10 kHz loop. Deterministic bare-metal execution. Measurable worst-case latency. No RTOS required.
This is what your OBC sees when it reads the EPS over I²C at 400kHz. Values update in real time. Inject faults to see the protection system respond.
University CubeSat programmes provide flight heritage. Canadian NewSpace companies provide commercial scale. Federal agencies provide validation grants. Each accelerates the others.
GomSpace P31u: ~$5,000. EnduroSat EPS: ~$4,400. AAC Clyde Space: ~$5,000. Jisa Dynamics EPS-1U: CAD $1,800 from. The price differential funds a PhD student's salary for six months.
An 18-month programme from simulation evidence to first paying customer.
Jisa Dynamics was founded in Moncton, New Brunswick by Arpit Patel — an engineer with over a decade of PCB and embedded systems experience, including spacecraft mission engineering at ISRO. The company name carries personal weight: Jisa is a combination of his daughters' names, Jinal and Satvi.
The gap Jisa Dynamics addresses is specific and real: Canadian universities and NewSpace startups need affordable, well-documented orbital power systems eligible for Canadian government grant funding. European suppliers charge 3–4× more and provide no co-development support. There is no Canadian alternative. Until now.
The company builds with institutional discipline from day one — JISA-STD-001 configuration management, AS9100D-compliant documentation, and a Master Test Plan that traces every requirement to a physical measurement. This is not typical for a pre-revenue startup. It is how flight hardware gets built.
