Satellites are like any other vehicle inasmuch as they have two main parts: the generic vehicle itself and the specific thing it carries (the payload) to do its unique job. The "vehicle" part of a satellite is called the bus, and it includes the outer case, the solar panels and batterie...
Satellite internet providers don’t use telephone or cable lines to get you connected. They instead use satellites to send and receive information and it all starts with your internet provider’s satellite in the sky. From there it will communicate back and forth to the satellite dish your prov...
By constantly resetting and re-checking its time against the GPS signals coming from the satellites, a lowly smartphone gets atomic-clock accuracy "for free." Differential GPS GPS works pretty well, but inaccuracies do pop up. For one thing, this method assumes the radio signals will make ...
But how do satellites___up without falling down, you___ask? Take a strong rope. Tie a small stone to one___to make a sling. Rotate the sling using one hand, you will___that the rope straightens out and becomes___as the sling rotates. As soon as you stop rotating, the rope sla...
Some technology uses satellites (卫星) to communicate. Satellites are also used to examine the changes in the Earth’s climate (气候) and seas, for weather report and for military (军事). We also use satellites in food production. Because of the use of space technology in crops, fewer and...
Weather satellites provide more than just an extraterrestrial view of weather; they also carry sensors to measure temperature, moisture and solar radiation. It's one thing to know what's happening now, but how do meteorologists transform all this data into an idea of what tomorrow's weather...
It connects computers, satellites, mobile devices and other gadgets together in a massive network millions of times more intricate than the original ARPANET. And to think, we owe it all to a silver beeping ball that once orbited miles above the Earth's surface. A Matter of Protocol The ...
The shuttle was designed to deploy and retrieve satellites as well as deliver payloads to Earth orbit. To do this, the shuttle uses the Remote Manipulator System (RMS). The RMS was built by Canada and is a long arm with an elbow and wrist joint. You can control the RMS from the aft...
These aircraft systems, essential for safe flight, include navigation equipment and communication systems that connect with ground-based stations and satellites. Any interference, even from seemingly harmless devices like cell phones, could potentially disrupt these critical aircraft instruments and compromise...
Orbiting above the earth's surface at precise positions is a satellite constellation of 24 GPS satellites. Each one is referred to as abirdand uses radio waves to communicate with other satellites to determine an exact location on the earth. These satellites use the World Geodetic System, known...
