An US$450 million investment from Apple’s Advanced Manufacturing Fund provides the critical infrastructure that supports Emergency SOS via satellite for iPhone 14 models, according to an article on the Apple Newsroom site.
Available to customers in the US and Canada beginning later this month, the new service will allow iPhone 14 and iPhone 14 Pro models to connect directly to a satellite, enabling messaging with emergency services when outside of cellular and Wi-Fi coverage.
A majority of the funding goes to Globalstar, a global satellite service headquartered in Covington, Louisiana, with facilities across the US. Apple’s investment provides critical enhancements to Globalstar’s satellite network and ground stations, ensuring iPhone 14 users are able to connect to emergency services when off the grid. At Globalstar, more than 300 employees support the new service.
“Emergency SOS via satellite is a perfect example of how American ingenuity and technology can save lives,” said Jeff Williams, Apple’s chief operating officer. “We are proud this service is enabled by leading US companies, and that our users can explore off-the-grid areas knowing they are still within reach of emergency services if they are in need.”
Delivered in partnership with Globalstar, Apple’s Emergency SOS via satellite service utilizes the spectrum in L and S bands specially designated for mobile satellite services by ITU Radio Regulations. When an iPhone user makes an Emergency SOS via satellite request, the message is received by one of Globalstar’s 24 satellites in low-earth orbit traveling at speeds of approximately 16,000 mph. The satellite then sends the message down to custom ground stations located at key points all over the world.
Once received by a ground station, the message is routed to emergency services that can dispatch help, or a relay center with Apple-trained emergency specialists if the closest emergency services location is not able to receive text messages.
The ground stations use new high-power antennas designed and manufactured specifically for Apple by Cobham Satcom in Concord, California. Cobham’s employees engineer and manufacture the high-powered antennas, which will receive signals transmitted by the satellite constellation. Along with communicating via text with emergency services, iPhone users can launch their Find My app and share their location via satellite when there is no cellular and Wi-Fi connection.
Apple says that, to increase reliability and coverage, these new antennas were installed in all Globalstar worldwide ground stations, including new ground stations in Nevada and Hawaii, as well as existing facilities in Texas, Alaska, Florida, and Puerto Rico. Several antennas at each ground station communicate with the satellites and relay the information provided by the user so they can get the help they need.
