The choice between which satellite communication device can be both tricky and time-consuming; hence this all-encompassing guide aims to cover all of your questions, including:
- What are satellite communicators?
- What options are offered at Johnny Appleseed GPS?
- Which device best suits you?
What Is A Satellite Communicator?
A satellite communicator is a device that enables users to communicate and send SOS requests outside of standard mobile phone tower coverage, utilising varying satellite networks.
There are 2 types of communication methods, 1-way and 2-way communication.
1-way Communication
- Only allows users to send outgoing communications whether it’s a message or an SOS request.
- In events where daily check-ins are required or simply want something for emergencies, these devices may be ideal.
- Users include: hikers, solo expeditions, and short trips
- 1-way communication devices are also substantially cheaper, adding affordability to their appeal for casual outdoor enthusiasts or those who may not need extensive communication capabilities.
2-way Communication
- Allows users to send and receive messages which may be extremely beneficial when needing to go back and forth between emergency services
- In group expeditions, the ability to coordinate information across team members, all in real-time may enhance security, reliability, and efficacy.
- Users include: research teams, group expeditions, and professionals travelling throughout remote regions.
Some devices also allow basic GPS waypoint marking and TracBack capabilities.
Why Would You Choose A Satellite Communicator
Satellite communicators offer a compelling and reliable alternative to traditional personal locator beacons (PLBS) and satellite phones, providing reliable communication and enhanced safety features in remote areas. Whilst PLBS are excellent for sending SOS signals, satellite communicators often include additional features such as safety check-ins, personalised messaging, and even weather updates, making them the preferred choice for adventurers and outdoor enthusiasts.
When compared to satellite phones, satellite communicators have several advantages. Device costs, subscription plans, and call costs associated with satellite phones can be significantly higher. Additionally, satellite phones on average can be bulkier and less portable. For users who don’t require remote internet access or phone calls, satellite communicators provide a more economical option to stay connected without losing the sense of independence and adventure.
Imagine embarking on a desert crossing or through an undiscovered rainforest; PLBs and satellite phones can give you the peace of mind of knowing that you are covered in an emergency, but they cannot enrich the experience during these remote expeditions. Satellite communicators enable you to share progress and the special moments from your journey with colleagues and loved ones.
How does SOS and Emergency messaging work
When using the SOS feature on a satellite communicator, the user activates the SOS button (usually by holding the button for several seconds), which sends an emergency signal along with their GPS location to a monitoring centre or emergency services. This signal often includes the user’s status and relevant information that can assist responders.
You can also have designated contacts that will receive communication in an emergency.
-
- Whilst Devices provide your location to emergency services, the frequency of location updates varies among different devices (i.e. every 2-10 minutes)
- The device may provide confirmation that the SOS signal has been sent, and in some cases two-way communication may allow for further instructions or information exchange with emergency personnel, enhancing the effectiveness of the response.
- This may be particularly useful when moving from the original requested location for several reasons such as an immediate danger. Informing emergency services as to why you have moved, allows workers to function with greater knowledge in each situation.
Types of Devices
Knowing which satellite communicator to choose from may be easier when allocating them into 2 categories; Needs an App vs Has an App.
Needs an App
Devices that need an app, require that the satellite communicator must be paired/connected with a phone and supported app.
- The device on its own may allow users basic features such as check-ins or a preset message; however, the majority of the value from both the device and subscription plan comes when utilising the phone.
- Custom messages, weather updates, and location requests are some of the benefits you’re paying for that may be lost when not using your phone.
Has an App
A device that has an app allows users the convenience of performing the majority of the actions from the device, either with the help of an onboard keyboard or screen.
- Creating custom messages, viewing weather updates, and even having basic navigation are just some of the benefits when using this type of device.
- Some users may prefer still pairing the device with their phone for the larger screen, and easier message formatting.
Plans – Year Round use vs short trips
Each Satellite communicator requires an active subscription. Plans are available depending on multiple factors including; length of use, number of required custom messages, and location requests.
- Devices may also contain a minimum monthly contract, activation fees, and suspension fees.
Iridium vs Globalstar
There are 2 primary satellite networks used for the devices listed here.
The Iridium satellite network which poses 100% global coverage, consists of 66 low-orbiting satellites that circle the Earth roughly once every 100 minutes.
- Whilst coverage is guaranteed the reception strength may vary depending on the satellite cycle.
The Globalstar satellite network does cover around 80% of the globe, utilising 32 primary (2nd Generation); however, the gaps are primarily over open water with a more accurate description being over 90% land coverage.
- Whilst general hardware may be behind the Iridium network, it provides essential communication services in its coverage areas.
Globalstar is particularly effective for users in North America, Europe, and Australia, where its services are most robust, making it a viable option for those who do not require the extensive global reach of Iridium.
In contrast, Iridium’s network is favoured for its reliability and ability to maintain connections in remote locations, including polar regions and open seas, making it the preferred choice for users who need consistent communication regardless of their location.
