X-ray pulsar-based navigation and timing (XNAV) or simply pulsar navigation is a navigation technique whereby the periodic X-ray signals emitted from pulsars are used to determine the location of a vehicle, such as a spacecraft in deep space. A...
A pulsar (pulsating star, on the model of quasar) is a highly magnetized rotating neutron star that emits beams of electromagnetic radiation out of its magnetic poles. This radiation can be observed only when a beam of emission is pointing toward...
Celestial navigation, also known as astronavigation, is the practice of position fixing using stars and other celestial bodies that enables a navigator to accurately determine their actual current physical position in space or on the surface of the...
Radio navigation or radionavigation is the application of radio waves to determine a position of an object on the Earth, either the vessel or an obstruction. Like radiolocation, it is a type of radiodetermination. The basic principles are...
X-ray pulsars or accretion-powered pulsars are a class of astronomical objects that are X-ray sources displaying strict periodic variations in X-ray intensity. The X-ray periods range from as little as a fraction of a second to as much as several...
The Neutron Star Interior Composition Explorer (NICER) is a NASA telescope on the International Space Station, designed and dedicated to the study of the extraordinary gravitational, electromagnetic, and nuclear physics environments embodied by...
PULSAR: Lost Colony is a science fiction space exploration video game by independent developers Leafy Games, LLC. The video game was greenlit on Steam Greenlight on October 3, 2013, and was later funded successfully on Kickstarter on October 31,...
Navigation is a field of study that focuses on the process of monitoring and controlling the movement of a craft or vehicle from one place to another. The field of navigation includes four general categories: land navigation, marine navigation,...
The Nissan Sylphy (Japanese: 日産・シルフィ, Hepburn: Nissan Shirufi) is a compact car produced by the Japanese car maker Nissan since 2000 as the successor to the Nissan Pulsar. The Sylphy has also been marketed in export markets under several other...
The Nissan Tiida (Japanese: 日産・ティーダ, Hepburn: Nissan Tīda) is a compact car produced by the Japanese manufacturer Nissan from 2004 to 2023 through three generations. Depending on the market, the Tiida was also marketed as a subcompact car,...
