gderamel | Iridium to introduce 2-Way Txt Capabilities
Figured I share this with the group... especially for those thinking of investing in any new Satellite messaging gadgets.
Iridium, which operates a high-earth-orbit network of satellites is about to introduce a 2-way global messaging system. They've signed an agreement with five partners who will each develop their own gadgets (press release).
I have a Spot Messenger which relies on the GlobalStar Satellite network. It works okay in the low latitudes (<50 degrees); but apparently in the higher lats - its useless. And, don't bother with their new Spot 2... it's a bear to setup and the texting capability - if you want to call it that - is awful.
*Regarding impact on 406 mhz ELTS - I'm not sure which of these two satellite networks they rely on, but I'm sure this Iridium announcement will have an impact on that market as well. I was told GlobalStar is financially very weak.
EDIT:
*406 MHz ELTS rely on the COSPAS-SARSAT satellite system, NOTHING to do with the Iridium or GlobalStar satellites. Although also a low-orbit system, the COSPAS-SARSAT system, has a dedicated geostationary network of satellites that covers the polar regions (LEOSAR satellites). If your interested in how the 406 ELTs get their coverage, click on the COSPAS-SARAT link.
