The CCSDS Telecommand (TC) and Telemetry (TM) standards are today being employed for a large number of scientific and commercial spacecraft. Using this standard allows reduced costs for on-board, ground and test equipment, as well as for spacecraft testing and in-orbit operation. This paper introduces the CCSDS/ESA standards, and presents the supporting standard components developed by ESA and ...

JUNO’s investigation focuses on four themes: origin, interior structure, atmospheric composition and dynamics, polar magnetosphere. Using a spinning solar-powered spacecraft, the Juno equipment will obtain global maps of the gravity, magnetic fields, and atmospheric composition of Jupiter from a unique polar orbit with a close perijove. JUNO carries in fact precise, high-sensitivity radiometers...

For equipment and systems that are too expensive and too important to fail such as launch vehicles and spacecraft, the actual reliability is dominated by infant mortality failures that occur soon after dynamic environmental ATP that is used to eliminate the equipment that will fail prematurely. Premature equipment failures greatly increase risk getting to space and working in space, slowing dow...

Fully autonomous, on-board orbit control was flight demonstrated on UoSAT-12. This technology was developed to reduce operations cost. It does this using less propellant than traditional orbit maintenance, but also opens a new array of potential mission applications. Because the position of the spacecraft is controlled and, therefore, known at all future times, users can plan applications witho...

[Abstract]: With the rapid development of space technology, more and more spacecraft have been launched into space, at the same time, the number of space debris increased dramatically, the probability of collision between space debris and spacecraft arise accordingly. To evaluate the collision effect, some evaluation methods should be studied. The paper introduces some evaluation methods accord...
