Ultra-Robust Electrical Power System

Batteries are a central pain-point for mission lifetime in the nanosatellite sector. We have developed a unique battery architecture that resolves this. For an equivalent mass/volume to conventional lithium-ion architectures, our solution:

Increases operational lifetime typically 5X

Simplifies thermal and power management systems

Is inherently more robust, reliable, and flexible

Operates consistently over a wider temperature range

Operates at 85% depth of discharge with 80%+ capacity retention after 25,000 cycles

The product is readily scalable from 40Wh-200Wh. The EPS is state-of-the-art with all required interfaces, sensors and safety features.

The example below, for a 40Wh-system, spells out the deltas one can expect. To clarify the value proposition for your mission, just reach out to us: hello@orbastro.com. We will be ready to ship qualified products from late Q2 2020 onwards.
