What is a GPS satellite communicator?

While there are a range of functionalities relative to satellite communicators, the basic function of a satellite communicator is to provide your location and connect you with search-and-rescue personnel in the event that you need to be rescued. Many other communicators also allow you to send and receive short messages to your various contacts while also receiving updates on weather. Some devices even allow you to connect to the internet and update your social media accounts! In short, a satellite communicator is a basic means of communicating where you are when you aren’t where you want to be.

How are satellite communicators different than cell phone?

Cell phones use cell towers to receive and relay signals (not too surprising). Given the dependence on cell towers, cell phones are dependent on the network in which they are operating for optimal service. Unless you have a satellite phone that operates off of Global Satellite Positioning (GPS) networks, you very well may not receive coverage in remote areas of the world, which is exactly the problem you will want to resolve if you happen to be stranded in such areas.

Satellite communicators operate off of satellite networks, naturally. Given that these satellites are constantly in orbit, as long as you can clearly convey and receive a signal (which usually requires only that you have access to some clear sky overhead), you can connect to the GPS network. Given the increased reliability of satellite networks, having a GPS satellite communicator provides a valuable service when your other devices can’t connect.

How do satellite communicators operate?

There are some different classifications for satellite communicators that influence their functionality. The simplest models are personal locator beacons (PLB). Similar to devices used on boats, a PLB emits an SOS alert when you push a button, allowing you to alert search-and-rescue personnel of your status and positioning. You will not be able to use a PLB for any other types of communication, however.

The next advancement in satellite communicators is the one-way satellite messenger. With these devices, you can send out a specific message to whomever you are trying to communicate. This is advantageous if your content is simply pertaining to less urgent matters such as a delay in arrival rather than if you are lost. Once again, you will not be able to receive any messages.

The two-way messenger allows you to both send and receive messages. These messages can be to your preferred contacts or to search-and-rescue personnel. Some even allow you to receive weather updates or updates on your other accounts. A key element to note with regard to two-way messengers is whether they rely on a phone connection in order to power connectivity. Typically, two-way messenger devices will pair with a cell-phone, however connectivity and reception capabilities may still be limited. Ultimately, with two-way devices, you will need to account for having a charged cell phone available in order to use the device.

9/11 was a horrific act of terrorism which was compounded by the lack of communication systems available during the time. With everyone making phone calls simultaneously it dramatically slowed down cellphone networks.

How are they powered?

Most satellite communicators are powered by rechargeable batteries, generally Lithium ion. Some require traditional AA batteries. Battery life can range from 100-240 hours, which is roughly 4-10 days of constant usage. Depending on your usage and how long you plan on venturing, it’s worthwhile to invest in a backup battery or a solar-powered charger so that you can keep your device ready to serve in the event that your trip isn’t going as planned.

Which satellite networks do satellite communicators use?

There are different types of satellite networks. Low earth orbit networks feature satellites orbiting at an altitude of 1,000 miles or less above the Earth’s surface. Multiple satellites constantly rotating around the Earth provide constant satellite coverage. Geostationary (GEO) networks are positioned at roughly 22,000 miles above the Earth and, given that they rotate at a speed nearly equal to Earth’s orbit, they are generally fixed in position.

Inmarsat is a GEO network that is popular given its global reach, though coverage is limited near the poles (sorry aspiring polar explorers).  Depending on the service you choose, you can receive voice and data coverage. Ligado is considered one of the pioneers of future satellite technology and can integrate with land-based communication networks. It works best with push-to-talk devices. Iridium is one of the most popular satellite networks as it operates the largest commercial communications satellite network. Iridium offers voice and digital operation capabilities. The Global Positioning System (GPS) is a satellite network that is used by federal and civilian entities and which serves as another means of transmitting and receiving information, particularly regarding navigation. Another emerging satellite network that is increasing its operability is the Galileo network, which is a featured network for some device providers such as Garmin.

While each satellite network is considered to have its merits, Iridium is often the preferred network for satellite communication devices given its range of applications regarding data transmission and communication and that it offers worldwide coverage without any coverage gaps. If you’re looking on traveling to remote parts of the world and don’t want to worry about whether your device will work or not, an Iridium compatible device is a sound option.

Internet coverage and natural disasters

As many have unfortunately experienced during a natural disaster, internet coverage does not always prevail. Various routes of damage include flooding or damage to cell towers that interrupts cable and data transmission. In other regions, earthquakes, fires and hurricanes can pose similar damaging possibilities to cell and wi-fi infrastructure. Given that having internet access can prove a vital lifeline to coordinate rescue efforts in the case of a natural disaster, being without phone or internet access can be not only unpleasant but life-threatening.

If you live in a disaster prone area, investing in a satellite communicator can help you to keep your connectivity when your local infrastructure is down. Given that satellite coverage is universal if you use the appropriate network, and many devices also connect to wi-fi and cell networks when in range, having a satellite communicator proves a reliable backup in the event that your local network is down. The main caveats are that satellite communicators vary with regard to data transmission and receiving. Likewise, if you happen to still be in the path of the storm and without clear skies, your data transmission may be slowed. Ultimately, satellite communicators are just that: communicators in the event of an emergency. You won’t be able to rely on them as internet hotspots or for any significant downloading. Better to hope and pray that the internet comes back on soon if that’s the case.

Which satellite communicator to choose?

Whether you’re shopping for a simple life-saving device or in the market for something that can give you a more reliable means of communication when you’re in the backcountry, there are a variety of criteria that you want to keep in mind so you can choose the best device. Considerations such as cost, network expenses, network reliability, durability, and operating capacities are some of the many features and attributes that you should consider when choosing the best satellite communicator.
