As part of the EV-2 Cyclone Global Navigation Satellite System (CYGNSS) mission team, Surrey will be providing the Delay Doppler Mapping Instrument (DDMI) for eight Observatories designed and built by the University of Michigan and Southwest Research Institute (SwRI). Following the success of the GPS ReOectometry Experiment on the UK DMC 1 satellite… (More)
This paper presents the latest development in SSTL's successful SGR range of Space GNSS Receivers. The SGR-ReSI (Remote Sensing Instrument) is a highly versatile and uniquely capable GNSS receiver that has been designed with the low-cost, microsatellite market in mind. Based on COTS parts, the SGR-ReSI builds on the expertise SSTL and SSC have developed in… (More)
This paper is a review on Surrey Satellite Technology Ltd's developments in Space GNSS receivers. Hardware implementations of the UK-DMC as well as the imminent flying SGR-ReSI are briefly summarised. Past sets of data obtained by the disaster monitoring satellite, UK-DMC, are re-processed in order to acquire for Satellite Based Augmentation System (SBAS)… (More)
This paper discusses the new GNSS receiver architecture being designed by SSTL, and its preparation for use in space. The first application is the SGR-ReSI experiment that will be flying on the TechDemoSat-1 mission in 2013. This will allow the collection of GPS Reflected signals for validating ocean models, and also an early prototype service to notify… (More)
