Globalstar - Is It Getting Better ?

[teejayevans]

Here we are in 2012, the GS network of satellites is suppose to be improving, so anybody got any 1st hand experience? Do you use it for email/data?

I'm thinking about the latest $40/mon unlimited special, but if I can't replace my cell phone, I don't think it's worth it.

Depends on where you are. I use mine primarily off-shore out of range of cell phones mainly for getting weather gribs. The service is better but this Fall still wasn't good enough for phone calls. All the satellites are not yet activated.

I have had Globalstar since 2001 and the service is better now than it has been in years. Since the worst in 2007, they have launced several new satellites and put them in service. An additional group launched in December is not yet in service, but should be shortly.

I just returned from a trip to SW Florida and it is about 60% or better now that additional satellites have been put in service. Look on their website and download the Calltimes tool and you can see how many minutes it is available and when in your area. I was able to talk uninterrupted during my calls. I also used it to download grib files and it worked just fine for that. Don't expect to replace a cellphone - even if it is 100%. It is line of sight to the satellite, but will work in the cabin of a sailboat

I made the mistake of using Global Star in 2004-2005. Very poor service in many areas including NW Carib (as I recall there was even a class-action law suite against GS around this time. I did not participate, but I did refuse to pay my last bill -- which is probably more than I would have gotten from the suit anyway). Good service in the "oil patch" of the Gulf of Mexico.

I now have a SPOT device. Unfortunately, they use GS for their message delivery so, at least here in the NW Carib, message delivery fails quite often. SPOT recognizes this is a problem and offered me a $50 discount to renew this year. They told me that GS is deploying more satellites and land terminals, but I've been hearing this since 2004.

The fundamental problem is that Global Star is not a true satellite based system. They use the satellites for interconnecting land based antennas. So if you are not in range of one of their land based antennas then you have no service. Iridium is true 100% satellite based, but of course more expensive.

It will not replace your cellphone. It will however allow you to retrieve voice mail and make calls when out of cellphone range and the bird is insite. It averages 30 mins an hour uptime.

That's not true. The satellite has to be in view of a land based receiver. It will not repeat to another satellite like Irridium will. The uplink from the phone is to the satellite.

Probably the more correct term I should have used is "gateway station". However, even if my understanding of the interaction between phone/satellite/gateway station is a bit off, the bottom-line is that If you are not within the coverage area of a "gateway station" then you do not have service (just look at their coverage map and you will see this correlation very clearly). If they were fully satellite based, like Iridium, then their coverage areas would be the earth footprint of the satellite signal. Thus, if you are in the mid-atlantic or mid-pacific (or NW Carib as in my case) then you have no coverage via GlobalStar because there are no gateway stations in range (see their coverage map to verify this).

This is also how the issue was explained to me by Globalstar regarding their poor coverage in the NW Carib. Back then, they showed coverage in the NW Carib (and many other places where they did not in fact have it). I noticed that they have now updated their coverage map to explicitly indicate this lack of coverage in the NW Carib and a few other locations.

Perhaps a bit clearer explanation is presented below (snip from a WikiPedia arcticle).

"Due to the lack of inter-satellite linking, a satellite must have a gateway station in view to provide service to any users it may see. The use of gateway ground stations provides customers with localized regional phone numbers for their satellite handsets. But if there are no gateway stations to cover certain remote areas (such as areas of the South Pacific and the polar regions), service cannot be provided in these remote areas, even if the satellites may fly over them"

I think that's what he was saying...

Does anyone have experience with IsatPhone Pro? This looks like it might be a lower-cost alternative to Iridium. It uses the Inmarsat constellation and the phone is about half the price of a new Iridium. The airtime seems to be cheaper than Iridium, but the airtime plans are pretty different, so it's hard to tell for sure.

I'm happy with my new Iridium phone, but some friends are considering the IsatPhone Pro.

Based on this review, it doesn't appear to be very good:
