Sentence examples for descent guidance from inspiring English sources

Then based on the real-time sampling optimal feedback control theory, the Mars powered descent guidance (PDG) algorithm is designed and analysed.

Taking the trajectory generated by the improved ZEM/ZEV algorithm as the initial guess history of the MPSP method, and the virtual control history as its control history, we develop a multi-constrained fuel suboptimal powered descent guidance law with the help of the high computational efficiency of the MPSP technique.

Third, some useful related technologies developed in China's current aerospace projects are pertinently summarized, especially on entry guidance, parachute descent, autonomous hazard avoidance and safe landing.

Other on-board systems tested during the descent included the autonomous navigation, guidance and control systems.

Titan's thick and dense atmosphere means that landing dispersions of spacecraft are dominated by uncertainties in wind drift, and thus the feasibility of landing safely in the sea with a simple Huygens-like descent system (i.e. without guidance or propulsion) is dependent upon these uncertainties being small enough that the landing point dispersion lies within the sea.

Next, the state-of-art guidance technologies of entry and powered descent phases are analyzed.

Autonomous navigation and guidance in the Mars approach, entry, descent, and landing (AEDL) phase plays an important role in fulfilling a pinpoint landing mission.

As a key technology, Mars lander guidance system is intended to serve atmospheric entry, descent and landing (EDL) phases.

In this paper, the Zero-Effort-Miss/Zero-Effort-Velocity (ZEM/ZEV) optimal sliding guidance (OSG) scheme is applied to the Mars powered descent phase.

Inside Mission Control Center in Houston, Texas, computer engineer Jack Garman told guidance officer Steve Bales it was safe to continue the descent, and this was relayed to the crew.

No such guidance has been published for people of black African descent.
