Posted on June 14, 2023
There’s nothing quite like the exhilaration of exploring the great outdoors. Veering off the beaten path on your trail run, boating in the most serene areas, and simply enjoying the beauty of nature are some of the best experiences we can have.
As an outdoor enthusiast, you know using a smartphone for communication while you’re on your adventure isn’t enough. You’ll often travel to remote areas where there isn’t any cell signal, leaving you with no way to communicate with others.
Luckily, technology has advanced and we can now communicate with anyone in the world from any location, thanks to satellite networks.
The advent of satellite communication now means that you never have to be cut off from loved ones, adventure buddies, or even emergency services.
In this article, we will discuss:
➡️ What a satellite communication device is.
➡️ How satellite communicators work.
➡️ Where you can find the best satellite messengers for your next adventure.
What Is Satellite Communication?
Simply put, satellite communication is the process of sending and receiving information using artificial satellites that orbit around the Earth.
Satellites are man-made objects that are equipped with communication systems, antennas, transponders, and other technologies to allow for communication.
Since its inception in 1958, satellite communication has become a vital technology that enables long-distance communication across the globe and facilitates applications like TV broadcasting, Internet connectivity, telephone services, weather monitoring, and navigation systems.
How does satellite communication work?
There are various components of a satellite required for communication. These are:
- The object that orbits the Earth as discussed earlier.
- Ground stations on Earth that communicate with satellites. They transmit and receive signals from satellites.
- The uplink process, which is when the ground station transmits a signal to the satellite. The uplink signals carry information like TV signals, two-way messaging, and Internet data.
- The downlink process, which is when the signal from the satellite is received by another ground station.
- The communication path is the pathway for transmitting signals between satellites and ground stations.
Signals travel from the uplink station to the satellite network and then from the satellite to the downlink station, enabling two-way communication over long distances.
Because there are thousands of satellites constantly orbiting the Earth, it allows for communication between devices no matter how remote your location is. This makes satellite communication the ideal system for those who love the outdoors.
What Is a Satellite Communication Device?
Also referred to as a satellite messenger or a satellite communicator, a satellite communication device is a portable technology that is designed to allow seamless two-way communication, particularly in areas where there is no other reliable communication structure, such as cellular coverage.
As manufacturers and stockists of a wide variety of these devices, we can’t stress just how vital they are for outdoor enthusiasts.
How do they work?
A satellite messenger uses the satellite communication technology described above to establish a connection with the satellites that are orbiting the Earth.
Typically, a satellite communicator is a compact and lightweight device, often designed to withstand harsh environments. These devices can send and receive signals to and from nearby satellites.
A satellite communicator is usually equipped with an antenna and a receiver that allows users to transmit and receive messages, GPS coordinates, and other relevant data.
How are they different from cell phones?
While a cell phone can provide convenient and feature-rich communication in areas with adequate cellular service, satellite messengers excel at providing communication capabilities in remote, off-grid, or emergency situations when coverage doesn’t exist.
The key differences between a cell phone and a two-way satellite communicator are:
- Communication technology: Cell phones use a terrestrial communication infrastructure such as towers and networks to communicate. On the other hand, satellite communicators use satellites to communicate.
- Coverage: Cell phones use coverage provided by cellular networks, which means coverage is limited to where there are towers and networks available. A satellite communicator offers global coverage in even the most remote regions.
- Functionality: Phones offer many features other than just communication, whereas satellite messengers are typically designed only for the purpose of communication.
- Battery life: Satellite messengers usually have a long battery life compared to a regular phone, making them ideal for extended use in areas without access to electricity.
- Price: Some satellite communication devices can be quite expensive compared to the price of an average smartphone. However, you will soon learn why they’re a worthwhile expense. Also, some brands require that users sign up for a subscription plan when they purchase their messenger. The good news is that if you purchase an ACR satellite messenger device, you won’t have to pay any subscription fees.
Who should use a satellite device for communication?
No matter where you are in the world, you can rely on satellite communication to allow you to send and receive messages and share your GPS location. However, a satellite communicator is typically designed for:
- Outdoor enthusiasts: Hikers, campers, trail runners, mountaineers, and any other adventurers who want to explore remote areas.
- The maritime industry: Ships, boats, and other vessels that operate in remote waters can use these devices to stay connected to on-land personnel, access weather reports, and for navigation.
- Aviation: Aircraft, especially those that operate in vast stretches of remote regions, can use satellite communication systems for air traffic control, weather forecasting, in-flight connectivity, and distress communication.
- Search and rescue: During natural disasters or search and rescue operations, satellite communicators provide responders and relief organizations with a way to communicate when cell phone infrastructure has been damaged or destroyed.
Satellite devices are also usually used by military and defense organizations, telecommunications service providers, and humanitarian organizations.
