Description
SSTL presents our radiation monitoring capabilities both current and upcoming with specifications and models of our current radiation monitor, a presentation of data collected on orbit, including from our technical demonstrator spacecraft TDS-1, and technical information on our latest monitor SPHERE.
RadMon is SSTL’s low mass, low power and highly adaptable radiation monitor. It is suited to a wide range of missions in LEO and provides operators with critical engineering data in near real time to identify and mitigate against the effects of the space radiation environment and provide mission operations support. RadMon has sensors to measure ionising dose in up to four locations, dose rate, protons and heavy ions.
Building on the success of RadMon, SPHERE is SSTL’s next generation radiation monitor, designed to extend the range of SSTL’s radiation monitor offering to new mission profiles in high LEO, GNSS and geostationary orbits. SPHERE is a low mass and low power monitor, measuring radiation effects in energy ranges proven to cause loss of function or performance in spacecraft systems. SPHERE has 2 proton telescopes, a heavy ion telescope and a deep dielectric charge monitor as well as up to 5 ionising dose monitors which can be placed remotely to monitor dose in specific systems or locations on the host spacecraft. SPHERE is offered in two variants – a COTS system for short duration missions or lower orbits and a radiation hardened version for longer durations or harsh orbits. It can also be specified with a range of common communication interfaces.
SSTL’s suite of supporting software allows us to offer a range of data products, from raw data for the scientific community, to fully processed information and reports which would be of use to a satellite operator.
Summary
SSTL presents our radiation monitoring capabilities both current and upcoming with specifications and models of our current radiation monitor, a presentation of data collected on orbit, including from our technical demonstrator spacecraft TDS-1, and technical information on our latest monitor SPHERE.
