Substituting these in the above equation, with Earth mass M = 5.974 × 10 24, G = 6.674 × 10 −11, and c = 2.998 × 10 8 (all in SI units), gives: This represents the fraction by which the clocks at satellites' altitude tick faster than on the surface of the Earth.
Google Earth. Google Earth is a computer program that renders a 3D representation of Earth based primarily on satellite imagery. The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles. Users can explore the globe by entering ...
Type I and type II errors. In statistical hypothesis testing, a type I error, or a false positive, is the rejection of the null hypothesis when it is actually true. For example, an innocent person may be convicted. A type II error, or a false negative, is the failure to reject a null hypothesis that is actually false.

It was kind of a big deal when Google (NAS: GOOG) reported earnings four hours early yesterday. Investors, used to the luxury of sitting back in after-market stillness to process fresh numbers ...
A high-altitude platform station ( HAPS, which can also mean high-altitude pseudo-satellite or high-altitude platform systems ), also known as atmospheric satellite, is a long endurance, high altitude aircraft able to offer observation or communication services similarly to artificial satellites. Mostly unmanned aerial vehicles (UAVs), they ...
Elevation. The elevation of a geographic location is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth 's sea level as an equipotential gravitational surface (see Geodetic datum § Vertical datum ). The term elevation is mainly used when referring to points on the Earth's ...
App Engine are web apps that run on the Google App Engine, a platform-as-a-service (PaaS) cloud computing platform which allows web developers to run their websites in Google datacenters. These web apps cannot take advantage of APIs to manipulate services such as TaskQueue (a distributed queue), BigQuery (a scalable database based on Dremel) or ...
