Basically, satellite communication is one long microwave link; transmission is comparable to that of existing microwave systems but with the added advantage of providing virtually all forms of telecommunications to areas which had not previously been well serviced.  3, record 1, English, - satellite%20communication

The ground data terminal(GDT) is the ground portion of the data link. The GDT communicates with the UAV [unmanned aerial vehicle] typically via microwave antenna that can provide line-of-sight communications. Where this is not possible, satellite can be used.  1, record 3, English, - ground%20data%20terminal

The Atomic Clock Ensemble in Space(ACES) is a programme to test the performance of a new type of clock that exploits and depends upon microgravity conditions. It consists of four key elements : a laser-cooled atomic clock; a hydrogen maser; a laser link for optical transfer of time and frequency; a microwave link for transfer of time and frequency.  2, record 4, English, - atomic%20clock%20ensemble%20in%20space

The atomic clock experiments are expected to improve the accuracy by a factor of 100 as compared to terrestrial atomic clocks. The ultra-precise time measurement will promote relativistic measurements and tests, and applications in atmospheric physics, geodesy, navigation and advanced telecommunications, as well as serve as a universal time and frequency reference from space.  3, record 4, English, - atomic%20clock%20ensemble%20in%20space

En avril 1997 PHARAO a été soumis à l'Agence spatiale européenne (ESA) dans le cadre d'une mission plus large appelée ACES (Atomic Clock Ensemble in Space). Son principe est de mettre à bord de la Station spatiale internationale (ISS) un ensemble comprenant des horloges ultra-stables et des méthodes de transfert temps/fréquences performantes. Dans la configuration de base de ACES, les deux horloges retenues sont PHARAO et un maser à hydrogène fourni par l'Observatoire de Neuchâtel (Suisse). Le transfert de temps est réalisé par un lien optique utilisant des impulsions laser très brèves (T2L2, fourni par l'Observatoire de la Côte d'Azur) et également par un lien dans le domaine micro-onde qui, lui, peut fonctionner par toutes conditions atmosphériques. En décembre 1997, la mission ACES [sera] montée sur une palette EXPRESS de la station spatiale en juin 2005.  2, record 4, French, - ensemble%20d%27horloges%20atomiques%20dans%20l%27espace

With a microwave system, essentially requiring line-of-sight links, this would in turn postulate either an extremely dense and costly network or ground stations,... or the provision of some other form of system architecture. An obvious solution exists in the form of a satellite data link system.  1, record 5, English, - satellite%20data%20link
