Over the next decade, hundreds of Earth observation satellites are expected to be launched as large constellations with the satellites operating in concert to provide intelligence for 100s of applications. In order to support these applications and achieve the maximum possible value from EO constellations SSTL is developing a CONstellation Satellite Taski...

This Phase 2 study continues the development and test of new GNSS antenna technologies put forward by SSTL in the Phase 1 study. Two different prototype antenna designs were produced by SSTL applying the technique of Composite Left and Right-handed Transmission Lines (CRL-TL), often referred to as meta-materials. Using CRL-TL allows the reduction in size ...

High concentration hydrogen peroxide (HTP) has the potential to become the propellant of choice for low cost, high performance satellite propulsion. Until now it has only been used in launch vehicles because HTP's long term stability depends on un-conventional material choices. The UK is already leading the way in developing HTP thrusters for small satell...

To develop a compact monitor to measure the radiation environment on a new generation of satellites being designed for deployment in geostationary/high-radiation orbits. The monitor will potentially use novel methods which will lead to more accurate data than previously measured at higher radiation levels.

Surrey Satellite Technology Ltd (SSTL) has a long history in advanced GNSS technology ranging from space GPS receiver design up to Galileo GIOVE mission and FOC payloads. SSTL is planning the development of a triple frequency antenna for new precise spaceborne GNSS applications, as suitable compact triple frequency antennas are not available commercially ...

This collaborative project between SSTL Ltd, Astrium Ltd and Spur Electron Ltd will accelerate the technology development of an innovative S-Band Synthetic Aperture Radar (SAR) instrument. This low cost, yet extremely capable instrument is the key enabler for a SAR satellite (NovaSAR) that completely changes the economics of the radar remote sensing marke...

In this study, SSTL will develop the prototype of a new generation of space GNSS receiver that will be sufficiently reconfigurable to not only track GPS but also Galileo signals (and others) in space. In collaboration with Chronos, the timing performance and robustness of the space receiver will be enhanced through the use of a disciplined (or otherwise s...

Today the development of onboard software is a high specialized and closed domain, which stiffles innovation and means that developing and deploying onboard software is expensive and time consuming. It is close to impossible to flight prove new, innovative onboard software solutions. The lack of a modern runtime platform in space is proving a hinderance i...

The evaluation and development of UK low toxicity ("green") propellants, thruster, tank and propulsion architectures for future spacecraft and satellite missions.

To develop structural aspects of new lunar orbit satellite to map lunar surface, collect scientific data and provide hardware infrastructure for future communications requirements.

As proven in terrestrial applications, the use of composite materials can result in significant cost reduction of component development and manufacture. A limiting factor in the application of these approaches in space applications is requirement for multi-function capability. Working with Surrey Satellite Technology Limited (SSTL), Advanced Composites Gr...

The aim of this project is to design a simple, accurate and affordable system to detect and locate sources of RF interference which affect commercial satellite services. A space based detector will be developed which can directly measure ground-based sources of radiation in any commercial band and the ground-based processing to localize the source of inte...
