The polar orbiting satellites (the ones that fly overhead) are the NOAA and DMSP satellites. The DMSP satellite is run by the Air Force who makes the data available to researchers. I use both to track and observe the icebergs. Both sets of satellites are U.S. owned and operated. GOES (US), METEOSAT (Europe), and GMS (Japan) are the geostationary satellites. They are great for observing the full disk of the Earth, but not the best near the poles.

SIRIUS is a service offering over 120 channels of satellite radio featuring digital-quality music, sports, news and entertainment programming when and where you want it. We use three satellites orbiting directly over the United States to broadcast over 120 channels of satellite radio to listeners throughout the continental US. SIRIUS delivers 65 channels of the best 100% commercial-free music in virtually every genre plus 55 channels of sports, news and talk. See similar questions...

A satellite mission may be studied and discussed for several years before NASA advisors approve it. Detailed designing and advanced technology studies then take 3 to 4 years, and a further 3 to 4 years are needed to build and test the satellite, and prepare it for launch. See similar questions...

When the ProMark2 is used for the first time it doesn't have any information about where the satellites are. About 15 minutes of tracking at least one satellite allows the unit to acquire a satellite almanac which contains the rough location of each satellite. After an almanac is acquired, tracking should occur within seconds of turning the unit on. Setting a user position can also help the receiver track faster the first time out.

astronomy satellites devoted to X-ray astrophysics, solar physics, infrared astronomy, and radio astronomy, e.g. ASCA, YOHKOH, ASTRO-F, and HALCA, See similar questions...

Again, this is most likely due to the computer clock/date setting. The satellites searched for are predicted based on the almanac, time, and location setting. If any of these is too far off the wrong satellites will be searched for. See similar questions...

Sirius" is the brightest star in the constellation Canis Major and the Northern Hemisphere. It was named after the ancient Egyptian god Osirus, who was represented pictographically as a dog, giving Sirius its more familiar name: the Dog Star. See similar questions...

WSI, the industry leading professional weather service, supplies the weather information for SIRIUS Marine Weather. For over a quarter century WSI has served federal, state and local governments; and the marine, aviation, agriculture, media and energy industries with unrivaled expertise in analyzing, forecasting and presenting weather information.

The most likely problem is the computer time/date setting. If it does not agree with the time received from the satellites to within 5 minutes it will not produce a navigation fix. See similar questions...

Weather satellites and other satellites used to monitor the environment cannot detect locust individuals or swarms. However, the highly sophisticated satellites used by the military can indeed detect locusts but these images are not available. Even if they were, it is unlikely that national and international locust organizations would have the ability to interpret the hundreds of images that would be produced on a daily basis.

No. Over the past 30 years, satellite technology has proven that it has very high service availabilities and low outages. They generally have better performance and availability than terrestrial circuits. See similar questions...

GPS sales are projected to be $9 billion per year in 2000. GPS receivers are increasingly interwoven into the fabric of commerce and recreation. New investment in low and mid Earth orbiting spacecraft is expected to be $30 billion by 2001. See similar questions...

The MediaMVP requires a URL associated with the internet radio station. XM or Sirius Satellite radio does not use a valid station Link associated with the stations. Therefore the MediaMVP will not work with these satellite radio services. This error is usually caused by attempting to playback a video file that uses DRM(Digital Rights Management). Video files that are copyrighted with DRM encoding are not supported. See similar questions...

Starting at $24.99/mo you can have 65 channels of the best 100% commercial-free music for your business. With SIRIUS Music for Your Business, you won't have to deal with the hassles of long-term contracts, buying expensive hardware, and paying for costly installation. Sorry, but free online streaming access is available only for personal accounts. See similar questions...

Yes, but they are faint (about magnitude 5.5 at their brightest). The NOAA polar orbiting satellites are approximately 500 statute miles above the Earth, are relatively small (not as large as the Space Shuttle, for example), and not very reflective. If you have a good viewing location away from large cities, where the Milky Way would be visible for instance, you can try to spot the NOAA satellites. The Heavens-Above web site can produce spotting information for any location worldwide. See similar questions...
