For missions with power hungry payloads, in its unmodified form, our CommSat power system can manage over 40A at a regulated 50V.

In its standard configuration, this power system is compatible with missions incorporating deployed, sun tracking arrays. The power system incorporates a number of main elements, including a 16 section Sequential Switching Shunt Regulator, hot redundant Battery Discharge Regulators, hot redundant Battery Charge Regulators and Power Distribution Module. A fully redundant and majority voted Main Error Amplifier provides a centralised control to the system and regulation of the 50V bus.

With slight modification, this system can acheive >100A at 50V.

The system is compatible with lithium ion/polymer battery technology.

Track record: GIOVE-A (GSTB-V2/A)*.

This subsystem is based on designs licensed from Surrey Satellite Technology Limited (SSTL). Subsystems for the missions marked '*' were developed and manufactured by SSTL alone. Clyde Space is wholly responsible for the development and manufacture of its subsystems and equipment.

Other products and services from Clyde Space


Spacecraft Batteries | Clyde Space

The cells that we have selected for space use have undergone extensive evaluation, in collaboration with ESA, to assess their suitability for the space environment - including leak and bulge tests. Our battery systems have integrated balancing circuitry, over-voltage and under-voltage protection, plus over-current protection via a PTC which can be replaced easily in case of short circuit.



This is due to the high quality systems and excellent customer service that we produce consistently for all of our customers. Over 40% of all CubeSat missions fly Clyde Space hardware, more than any other vendor. Clyde Space was the first space company to have an online CubeSat shop. Add CubeSat to basket and buy with your credit card'.


Electrical Power Systems

We also offer off-the-shelf power system products which have excellent performance specifications and extensive flight heritage. The designs are modular and have the flexibility to be easily configured to meet the requirements of bespoke projects. Clyde Space produce tailored Electrical Power Systems which are designed to your specifications.


DC-DC Converters

One is designed for Low Earth Orbiting small satellite applications, utilising COTS components and the other is for applications requiring very high reliability and radiation tolerances up to 100krads - note that this converter range can also be produced to 100krads ITAR free.


Solar Panels | Clyde Space | Glasgow

Clyde Space solar array design and manufacturing techniques have been developed based on traditional solar array assembly techniques, but adapted to reduce assembly costs in order to meet the tighter budget needs of the small satellite community.


CubeSat | EPS | Power Systems | ADCS | Structures | Solar Panels

Our solutions include complete or part Power Conditioning and Distribution Systems, Lithium Polymer Batteries, Solar Arrays and DC-DC Converters. In addition to our off-the-shelf products, Clyde Space has a wide selection of heritage systems for non-standard spacecraft. Our four main small satellite power system products are: SmallGEO Power; SmallSat Power; NanoSat Power; CubeSat Power.
