Since we know your company and work with you since 2004 we were a bit concerned in 2016 when you (at that time SSBV) have been acquired by Celestia Technologies Group. But after your visit and presentation about your strategy and R&D activities our worries disappeared. So far, we are very satisfied working with C-STS. Your responsiveness for technical or programmatic matters makes our life easier and allows us to complete our procedures faster. Your TM/TC Front-End unit is used a lot, almost 100% of the time. We use it to test our OBC’s and CDMU’s, thanks to it we can test many things. Simply put, every time we switch on the spacecraft we use your TM/TC Front-End. We are very confident about its performance and if there is an issue we are sure that it is not in your unit, but somewhere else. Moreover, front panel monitoring points is very helpful feature. It allows us to see the signal and this helps a lot especially during operations on the launch pad or in thermal vacuum chamber test campaign. We always recommend C-STS especially when we talk about new projects with European Space Agency. We always mention that it is a good company with very competent people. Fun fact: back in 2004 for ESA GAIA mission we started using your TM/TC Front-End unit. The same unit has been used in different project phases at multiple locations: UK, France, French-Guiana and Germany. In a period of 15 years unit has been shipped across the World and it is still in perfect operational condition. Honestly, we are expecting to use for another 3-4 years. Your TM/TC Front-End unit is very robust.
