From SPOT's website
Q: Tell me more about the commercial satellites that SPOT uses.
A: SPOT uses the Globalstar simplex data network to transmit messages. This is a proven data network that is also supporting tens of thousands of commercial and industrial data modems sending millions of messages each month for asset tracking and remote management applications. The simplex data network signal path works differently than the Globalstar satellite phone signal path, providing significantly better reliability and message completion rates.
With any new system, there is always a learning curve for the monitoring company dealing with emergency
services from other countries. My first suggestion would be call 000 for Oz - after all, who else would we call ourselves in an emergency. In Europe they use 112 for emergency calls - this is also available in Oz.
Help & 911 can be activated at the same time, so if needed you can have additional people contact 000. Since you can customise your messages for a trip, have something like - Help 'I need help because vehicle is diabled and/or injury requiring assistance. If you get an OK msg after this then its just vehicle. Note - we are moniting UHF channel XX for assistance', then send an OK msg.
Im sure that in the future there will be expansion on this system to notify of the situation with more detail.
At the end of the day - having this and an EPIRB is cheaper and more practical than HF & Sat phone. But being over prepared is never a bad thing when it comes to your family.
The more people use this system, the better the system will work. In a convoy situation, 2 vehicles can carry SPOT, if one sends for help,
home base knows that vehicle failure has happened, if both send for help, then its life threatening, and can raise help.
