Satellite Weather: Sirius Battles XM

The May issue of Powerboat Reports featured a comparison between Sirius' and XM's marine weather packages. They compared such items as features, update speed, costs, user interface, and data presentation.

The winner won based on the quality of the data and ease of use. One was much less expensive and all inclusive; the other, relatively expensive, requiring the top of the line package for the discriminating boater. The winner? Read the article.

Hi can I ask you a question? I'm glad I landed at this site (quite by chance. I pressed Next Blog and here you are) ... I'm fascinated by this satellite radio thing but the digital radio we have here in the UK is land-based, not "satellite" at all... so am I right to assume you have to have a dish installed to listen to this satellite radio like a TV dish? We can get radio stations over satellite TV already and more than double the population here use satellite tv rather than all the cable companies combined (far better choice of channels for one thing) ... does satellite radio exist in europe? What is it called? I'm fascinated to know more...
I'm at gledwood2.blogspot you can get in touch via my comments there.
All the best to you. Fascinating blog

Glad you found us and thanks for your comments.

I think what we call HD Radio is roughly equivalent to your digital radio. It is just starting to take off here as an answer to satellite radio.

Satellite radio uses a different frequency than satellite TV. Consequently, it is not bothered so much by the weather. It does not require a dish, but rather more a a puck, about an 11/2" or so in diameter and maybe 3/8" thick. They are quite small today. The antennae are omni directional, so they don't have to be pointing at the satellite; they merely have to be in the line of sight. The satellites are supplemented by terrestrial repeaters where the line of sight may not be so good, such as in the cities.

Satellite radio will be available in Italy in 2008 via WorldSpace. It will expand into other European countries in 2009. WorldSpace has made similar plans in the past and failed to deliver. WorldSpace and XM have working agreements between them that date back to the beginning of satellite radio. WorldSpace started out as a means of combating Aids in Africa. It is trying to transition into a satellite radio provider for Europe.

i also believe the european space agancy is working on satrad. read something about the antenna being built into the car roof. also they are supposed to use the k_u band and will rely on existing satellites.

Hi ,
Your work on the blog is fantastic. I’m influenced in a positive way.

Specifically, I got some nice information by visiting your blog http://satelliteradiotechworld.blogspot.com/

If you are interested, I would like to exchange links by placing a content link in your website. Don’t you think it would be nice for both our sites?

I’m waiting for your response.
Regards,
David
