If you’re flying over remote terrain where traditional communication methods may be unreliable, you may be wondering how anyone would be able to reach you in case of an emergency. This is where a personal locator beacon (PLB) or a satellite messenger can come into play.

PLBs are emergency devices that transmit distress signals via satellite. Pilots carry PLBs as a last-resort distress signal. If an aircraft crashes or becomes stranded, activating the PLB alerts search and rescue authorities.

Satellite messengers, on the other hand, allow customized two-way messaging via satellite networks. Pilots can use satellite messengers for emergency and non-emergency communications, trip planning, and keeping connected in remote areas. They provide SOS capabilities, location sharing, and text messaging.

Keep reading for a side-by-side comparison of the best PLBs and satellite messengers on the market today, and explore their crucial role they play in aviation safety.

How Do Personal Locator Beacons Work?

A personal locator beacon is a compact, portable device designed to send out an emergency distress signal in life-threatening situations. When activated, a PLB transmits a powerful distress signal on the 406 MHz frequency. This signal is picked up by a network of satellites, which then relays the information to local search and rescue teams.

A PLB is especially useful in remote areas where traditional communication methods like cell phones may be unreliable. It is accurate, portable, and cost-effective. Some newer PLBs also integrate GPS position data into the distress signal, narrowing the search area to roughly the size of a football field. This means that a PLB can be a crucial lifeline in case of an emergency if you’re flying over remote terrain.

Emergency Locator Transmitters

In 1973, after the disappearance of a Cessna 310 on a flight from Anchorage, Alaska to Juneau, Alaska, the Federal Aviation Administration (FAA) began requiring the installation of emergency locator transmitters (ELTs) in almost all aircraft.

Unlike PLBs, ELTs are units permanently installed on an aircraft. But similar to PLBs, they are designed to automatically activate in the event of an aircraft accident and send out a signal to search and rescue crews.

ELTs are also registered to their owners, allowing emergency responders nearly immediate access to information about who they’re looking for. They transmit a distress signal on the 406 MHz frequency.

Basic Emergency Beacon vs. Satellite Communicator

PLBs were approved for use in the U.S. in 2003. PLBs transmit a personalized signal on 406 MHz, an international distress frequency that can be received by the COSPAS-SARSAT satellite constellation. The National Oceanic and Atmospheric Administration (NOAA) monitors the system in the U.S, including PLB registration. That registration is good for two years and is required by law. One of the benefits of registration is that any distress signal will identify the owner and their personal info to search and rescue personnel.

PLBs fall into two general categories:

  • Basic emergency beacon: A basic emergency beacon is an emergency device that uses satellite technology to transmit a distress signal to search and rescue teams in case of an emergency. It is typically a one-way communication (SOS only) device. A basic emergency beacon does not require a subscription unless it offers upgraded features, such as one-way messaging.
  • Satellite communicator: A satellite communicator allows two-way, customized communication. It improves emergency response by enabling communication beyond cell signals. It offers features like text messaging, tracking, and SOS capabilities. A satellite communicator requires a subscription.

Tips for Choosing the Best PLB or SAT Communicator

There are several considerations to keep in mind when choosing the best PLB or SAT communicator. From distress signal strength and reliability to budget considerations, there is a tool to meet every pilot’s unique mission.

Distress Signal Strength and Reliability

PLBs are designed to send out a distress signal when activated. This signal is crucial for alerting search and rescue services. A strong signal ensures faster detection and response while guaranteeing that help can be summoned promptly even in the most remote locations. PLBs are built to withstand harsh outdoor conditions, but regular maintenance and testing are crucial to guarantee their reliability during emergencies.

Battery Life: Ensuring Longevity in Emergencies

Having a reliable device with sufficient battery life can be a lifesaver during emergencies. Here are several battery life-related factors to consider when choosing a PLB:

  • Standby mode: If you never have to activate your PLB, it can last anywhere from months to years without needing replacement or recharging.
  • Operational mode: When activated, a PLB should work continuously for at least 24 hours, as required by law. Some devices can last longer—up to several days or weeks—depending on usage and operation.
  • Battery longevity: Always check your device’s specifications and follow manufacturer guidelines for battery charging, maintenance, and replacement.

Satellite Network: Coverage and Accessibility

Having a reliable PLB with global satellite coverage ensures that help can reach you even in the most remote areas. Pay attention to the following as you evaluate your options:

  • Global coverage: When activated, PLBs transmit a signal that can be detected worldwide by the international satellite system. This means your beacon can be activated from anywhere on Earth’s surface, whether you’re traveling by air, land, or sea.
  • Emergency response: PLBs use satellite technology to send distress signals to emergency services, alerting them to your location and need for assistance. The signal relays GPS data, providing precise coordinates to local search and rescue teams.
  • Network reliability: Different PLBs use various satellite networks. For truly worldwide coverage, COSPAS/SARSAT and the Iridium network are the best options. Globalstar, employed by SPOT devices, provides more regional coverage.

SOS Only vs. Two-Way Messaging

An SOS only device is designed solely for emergencies. When a pilot activates the SOS button, the unit transmits a distress signal to rescue services. An SOS only device is simple, lightweight, and reliable for critical situations. However, it offers limited communication as there is no custom messaging or interaction beyond the SOS signal.

A two-way messaging unit, on the other hand, allows pilots to communicate directly with rescue teams. It allows pilots to send and receive messages, explain their situation, and get advice. Two-way messaging enhances communication and coordination during emergencies. However, these devices tend to be slightly heavier and more complex than the SOS only units.

Subscription Requirements: What You Need to Know

A PLB does not require a subscription unless it is a device that also offers messaging capabilities. SAT communicators, on the other hand, require ongoing payments to keep them operational, including:

  • Activation fees: Most services have activation fees when starting or resuming service.
  • Monthly/Annual fees: Monthly or annual subscriptions are available and can be selected based on your individual needs.
  • Additional charges: Depending on your plan, you might incur additional charges unless you’ve selected an unlimited option.

Budget Considerations

The average cost of a PLB/SAT communicator typically ranges from $200 to $500. The cost of the unit ultimately depends on every pilot’s unique needs and the unit’s functionality. A simple PLB with SOS signaling only costs much less than an advanced SAT communicator with a global hotspot. 

While a PLB does not require a subscription beyond the initial unit cost, a SAT communicator requires additional subscription fees, as already described.

Choose Your Personal Locator Beacon Wisely

If you are simply looking for a solid backup to an aircraft ELT, a basic PLB is the best way to go. Little maintenance is required, and the price for most models is reasonable. Given the similarity in cost, deciding between basic PLB models is largely a matter of picking which features and operating styles you prefer, such as waterproofing and protection against accidentally transmitting distress signals while testing the unit.

For pilots planning more extensive backwoods travel or flying over sparsely populated terrain, satellite messenger functions can offer a lot of safety options geared specifically for trips away from cell phone reception. It’s up to you to choose the device that will meet your unique needs.
