Talk:Globalstar

Copyright violation

The content source is now added to the additional content that was taken from a "public" site (www.globalstar.com).

I thought the previous content on this Globalstar page was very "Pro" Iridium outright slamming Globalstar. There was even Globalstar links in the “External Links” section that were pointing to Iridium content.

Also the Globalstar page, though most content (which was minimal to begin with) was factual, was mainly comparisons Globalstar’s competitor, Iridium.

The Globalstar page is suppose to explain what Globalstar is about, its technology, it’s service. djose 20:54, 25 April 2007 (UTC)Danny

Recent additions to this article seem to constitute a copyright violation from pages at globalstar.com. —Fleminra

Technical

It would be nice to have a bit more technical information in this article eg RF Power Output: 400 mW maximum (+26 dBm) Frequency Range: Globalstar Reverse Link: 1610.73 to 1625.49 MHz Globalstar Forward Link: 2484.39 to 2499.15 MHz

Feederlinks up to the satellites operate in C-band between 5091 and 5250 MHz. Feederlinks down from the satellites also operate in C-band, between 6875 and 7055 MHz.

All transmissions are Code Division Multiple Access (CDMA). http://www.decodesystems.com/globalstar.html

removal of TerreStar link

This edit removed the link to TerreStar. I am adding it back. Non-existance of a Wikipedia article does not imply non-notability of a topic. This is what Special:Wanted pages exists for. —Fleminra 09:15, 4 September 2006 (UTC)

Too much comparison

The article read like a comparison of Iridium against Globalstar, which I believe was not the intension. It could be better is the comparison is left for another article, or put as a section right at the bottom of this article. That would make it more informative, I believe. —The preceding unsigned comment was added by Wk muriithi (talk • contribs) 08:49, 20 February 2007 (UTC).

CDMA ... GSM Sim Cards

This is not true. Only the Ericsson and Telit phones use GSM standard sims, the Qualcomm GSP-1600/1700 phones do not have a simcard interface, but use CDMA ANSI-41 based authentication. Therefore the Globalstar gateways need to support both the CDMA/ANSI-41 and the GSM standards, which, however not all gateways do. This results in the lack of coverage for GSM-based phones in the eastern asian and caribbean region, as stated on the coverage map: http://www.globalstareurope.com/en/content.php?cid=300 cintema 13:59, 11 May 2007 (GMT)

The Qualcomm GSP-1600/1700 phones may not have a "SIM Card" per se, but they do have what I believe is an R-UIM card which stores the IS-95/ANSI-41 A-key used to authenticate the handset with the Globalstar network. The R-UIM card has the exact same size, shape, and electrical connector as a 2FF SIM card. I would like to find a reputable source for this so that it might be mentioned either in this article or in to-be-created articles about the GSP handsets. Please let me know if you know of such a source. DrDeke (talk) 19:20, 26 January 2013 (UTC)

Devas?

I propose "The Proposed Devas satellite system of India has been declared closed based on a decision of the Government of India in 2011." be removed. It doesn't have anything to do with GlobalStar directly, and from what I can tell from a quick googling is not a descendant of Globalstar either. It also breaks the flow of the article. If it does tie in with Globalstar, I would elaborate slightly as to how it's related. Here is an interesting article on the rise and fall of Devas though: http://www.hindu.com/fline/fl2805/stories/20110311280501100.htm — Preceding unsigned comment added by 173.29.128.199 (talk) 03:19, 8 December 2011 (UTC)

• Done. (Sentence about Devas is removed.) Not only does Devas have nothing to do with Globalstar, the 2011 event involving Devas was plopped into the Globalstar timeline between 2001 and 2002. Fish Man (talk) 14:15, 8 December 2011 (UTC)

Gateways

I am not sure I understand the function of and need for those regional Gateways. Is it that even if the phone on the ground can talk with a satellite, the satellite has to be able to talk simultaneously with a ground based communication network somewhere, or the call cannot reach anyone? Is that the basic purpose of the Gateway? Could two phones in the Southern Ocean, say, talk to each other without a regional Gateway as long as they see the same satellite? --Egmonster (talk) 20:19, 22 November 2015 (UTC)

The article doesn't come right out and say it, but the satellites have simple analog transponders, and apparently no switching gear on board. So my guess is that your call has to go to a gateway then back up to the satellite, even if both users have a view of the same satellite. This would make a good addition to the article if someone has sources. Kendall-K1 (talk) 20:51, 22 November 2015 (UTC)

Marketing / alternative facts

"The first call on the original Globalstar system was placed on November 1, 1998, from Qualcomm chairman Irwin Jacobs in San Diego to Loral Space & Communications CEO and chairman Bernard Schwartz in New York City."

This statement is obviously false - several rounds of phone calls would have been placed by development and test Engineers first, and the last few big software bugs worked out, before the CEOs got anywhere near it for a ceremonial phone call.

Perhaps the first "publicized" call, or "official" call, if you really want to stretch it, but still remain somewhat truthful. — Preceding unsigned comment added by 74.14.227.145 (talk) 14:34, 4 October 2017 (UTC)

Written Like an Advertisement

In the four years since the Advert tag was added to this page, I think it has been improved enough (mostly by other editors) to warrant the tag's removal. Does anyone disagree? If so, what remaining content would you say reads like an advertisement?

DrDeke (talk) 23:21, 19 May 2022 (UTC)

Having heard no objections, I am going to remove the advert tag.
