Three companies, three divisions, one engineering bench.

Vyovrinda is P9e's aerospace company, and its scope is the whole altitude spectrum rather than a single vehicle class. A quadcopter and a satellite are, at the level that matters, the same engineering problem — avionics, guidance and control, a command-and-telemetry link, a payload, autonomy, and a ground station. Vyovrinda builds that stack once and qualifies it to the altitude it has to survive.

• Unmanned aerial systems

  Multirotor, fixed-wing and hybrid VTOL airframes engineered around a defined payload and endurance envelope — with the flight controller treated as load-bearing structure, not software.

• Stratospheric & lighter-than-air

  High-altitude pseudo-satellites, balloons and airships — buoyant flight for persistence measured in weeks rather than hours.

• Satellites & subsystems

  Power conditioning, on-board computing, attitude control and communication subsystems for small-satellite missions, screened for the orbital environment.

• Ground segment

  Mission and sortie planning, telemetry and command, and the link hardware between operator and vehicle — one ground platform serving drones, HAPS and satellites alike.

Sasyaveda applies the group's automation and IoT engineering to farming. Field sensing, automated irrigation and climate control, and an agronomy layer that turns readings into a schedule a grower can act on — deployed across open field, protected cultivation and controlled-environment installations, and drawing on Vyovrinda's remote sensing for the view from above.

• Field & greenhouse sensing

  Soil moisture and EC profiling, canopy and micro-climate sensing, and weather stations built for years outdoors.

• Automated irrigation & fertigation

  Valve and pump control with dosing, scheduling and flow verification — running autonomously when the network link drops, which it will.

• Controlled-environment agriculture

  Climate, lighting and nutrient control for polyhouse and vertical farming installations.

• Agronomy & decision support

  Crop models, irrigation scheduling and advisories delivered through mobile apps built for the people standing in the field.

Savithru holds all of the group's solar, battery and energy engineering in one place. It runs from the plant — generation monitoring, string and inverter telemetry, performance analytics — through to the pack: battery management electronics and firmware, thermal and mechanical pack design, and the storage systems that sit between the two. Consolidating them was deliberate: generation, storage and the control layer between them are one engineering problem, not three.

• Solar generation & plant monitoring

  String, inverter and plant-level telemetry, performance ratio analytics, soiling and degradation tracking across distributed and utility-scale sites.

• Battery management systems

  Cell monitoring, balancing, state-of-charge and state-of-health estimation, protection logic and CAN integration — one signed firmware image with a documented failure behaviour.

• Storage & pack integration

  Mechanical and thermal pack design, busbar and interconnect engineering, and stationary storage for solar hybrid, backup and peak-shaving duty.

• Power electronics & analytics

  Conversion and conditioning hardware, plus the fleet analytics that turn a warranty claim into an argument you can win.
