insufficiency that the existing array fireworks display shell which has monotonic external appearance is lack of artistry and interest, putting forward that the external appearance array fireworks display shell is made into molds of the strap-on rocket, the shuttlecraft and the assembly missile array. The utility model improves the interest and the ent...
Phased-Array Radar In subject area: Engineering Phased array radar is a phased array antenna (PAA) radar and an electronic scanning radar. From: Spacecraft Collision Avoidance Technology, 2020 About this pageSet alert Discover other topics
Electronic offset pointing on de-yawed phased array antennas is achieved by computing a set of pointing control parameters on the ground, and uplinking the parameters for final processing on-board the spacecraft. The control parameters are derived so that only minimal changes to the on-board ...
Solar arraysare the primary power source on board most spacecraft. The solar arrays are deployed once the spacecraft is in orbit using special gimbals andretention and release mechanisms. The solar arrays are then oriented so that they are perpendicular to the sun’s rays. During eclipse period...
