Inmarsat, Iridium, & Globalstar...the horse race

Competitive heat is really building in the portable global sat phone/messenger sector, and once it gets sorted, it's got to be good news for those of us who venture beyond cellular networks. Last week Iridium announced that its smaller, cheaper 9602 SBD modem is ready ahead of schedule for some 90 "integration partners," and a few weeks before that Inmarsat detailed its IsatPhone Pro (due in June), including its game changing pricing. And while I discussed both of these developments here in January, it's Globalstar that may be the long term dark horse in this race...
Now we have heard fabulous forecasts for future satellite services before, which didn't work out, but also mentioned in the release is the "$738 million financing to fully fund manufacture and launch of 24 new second-generation satellites" secured last year. This is not exactly fresh news, and deals like this have collapsed before, but a sharp someone in the marine industry recently told me that the French government is behind this deal (because Thales Alenia Space is building all those new birds) and it's probably going to happen no matter what. Then again that Globalstar timetable only goes to a September ready-to-launch date, and this sat industry article seems to suggest that it needs to maintain its phone and Spot Messenger services to make it through the long haul. Which may explain in part why Iridium and Inmarsat seem so intent on chipping away at those businesses...

In fact, a sat phone specialist at the Miami show theorized that a relatively low cost IsatPhone with decent small data abilities might do a lot of what seems possible with Iridium's Small Burst Data technology. It's worth noting, for instance, that Inmarsat's recently introduced FleetBroadband 505 Emergency Calling service seems like it could work fine with the IsatPhone. But don't forget that "more than 90 Iridium partners have tested the 9602 for integration into new products" and that planned applications include "telemetry from unattended sensors, fleet management, ...tracking soldiers and military vehicles, and personal two-way navigation and mapping." Isn't this an interesting horse race?
We have an investment in an SSB/Pactor modem set up (it's getting delivered this month, in fact), because in two years we'll be off for a few years voyaging and will need GRIB files and (limited) SailMail in order to educate our son and assure our families we haven't sunk.
But I must say, if the price of satphones is approaching the $500 mark, they are very close to that "sweet spot" whereby purchasing one becomes a no-brainer, just like a PLB or a Spinlock PFD currently is. The utility of having one aboard (maybe next to the ditch bag) justifies the cost. I assume that if you use it rarely, there's a low "account fee", but there's a lot of reasons to make short voice calls or brief Internet forays using it in emergencies or when the SSB conditions aren't ideal and cadging a wireless connection isn't possible.
Thanks for the update.
