What services does the Iridium system provide?

The Iridium system is recognized for its global satellite communication capabilities, specifically designed to offer reliable services in remote areas where traditional cellular networks may be unavailable. The correct answer highlights the fact that the Iridium network provides digital voice and data services at a rate of 2.4 kbps. This rate allows for effective two-way communication, enabling users to make calls and send data, including messages and other types of information, across the globe without being hindered by geographical limits.

The 2.4 kbps data rate supports a higher quality of service compared to simpler systems that might offer lower data rates or basic connectivity features. Iridium's focus on digital transmission ensures better sound quality for voice calls and more reliable data transfers compared to older analog systems. The technology implemented in this network allows it to deliver efficient communication solutions that are critical for users in various fields, including maritime, aviation, and emergency response.

While other services or formats mentioned in the options may stem from different communication technologies, they do not accurately describe what Iridium specifically provides. This distinction is crucial for understanding the capabilities and advantages of the Iridium system in the competitive landscape of satellite communications.
