Satellite Simulator and Network simulation software Basics
This page covers network simulation software.It mentions satellite simulator basics,satellite delay simulator and its application notes.
The hardware device or software application which simulates satellite conditions in a controlled environment is known as satellite simulator. The one whuch introduces satellite network delay or latency is known as satellite delay simulator.
Various companies are developing it in order to support different variety of satellites such as GPS, Galileo, Geo-synchronous, Iridium etc.
Following application note describes GPSG-1000 portable satellite simulator from Aeroflex.
