  • Renting vs. Buying

To accommodate many adventurers, outdoor travellers or sailors’ needs and preference, there are two options to consider: renting or buying a satellite phone for boats. The most appropriate one would highly rely on the frequency and how long each sail would be in a year.

  • Power Source and Battery Life

At present, the only means to recharge your sat phone is to plug it into an electric power outlet traditionally. This concern would not be an issue under typical situations because nearly all vessels and yachts come with power sources for electronic devices.

However, as previously mentioned, if you’’ need to abandon the vessel, it is ideal to have with you a spare or two to completely and reliably recharge your batteries. A wholly charged one commonly last a period of 2 up to 3 hours of talk time.

Furthermore, some things that could affect the battery lifespan consist of the temperature and batteries. Extreme cold or hot could weaken the battery lifespan.

  • The Trip

In general, you should have an insight into where you are heading. This factor is quite essential when you sail or traverse in the waters where there are no landmarks that could function as your reference in determining your location.

Look through the location you are heading. There could be neighboring islands that have cell sites. These would have been a waste of your time subscriptions. More than that, several communication firms offer coverage at specific locations for a less expensive cost as compared to the global coverage that is provided by Iridium phones.

Apart from this, the kind of weather could have impact on the capabilities of your satellite phone to enable you to communicate outside. A timeline is helpful to have as this would assist you which days you’re going to reach specific destination. Having fundamental insight would be beneficial because this would indicate the minutes you may require for the satellite phone.

  • How portable is the satellite phone? Consider its weight, size and dimensions.

While there is no need to carry around the sat phone with you all the time since you’re staying inside the ship or yacht while voyaging when sailing, in instances that you and your companions need to abandon the vessel, this is worth considering.

Several options have their antennas built into the sat phone. Nonetheless, the antennas are mostly visible and come in a larger size. Moreover, they could be folded or stacked within the phone. Others are equipped with auxiliary antennas that are meant to amplify signals, particularly if more reliable internet connection is preferred.

  • Other Vital Features

There are options that are designed with SOS button. Here, you need to pay for the subscription. As you press it, the rescuers would be there to provide you the required assistance. A renowned subscriptions service is from GEOS. These are serviceable for a total of 140 countries, can respond and dispatch support 24/7.

Additionally, numerous systems sustain low bandwidth access of internet. Typically, the connection you would obtain is not as fast as LTE services or 3G. Other options are capable of broadcasting your exact GPS location. This feature is very convenient, particularly for rescuers, because they could monitor you instantly. Such a feature can provide your loved ones with the peace of mind of being updated with your whereabouts.

And, because we are in the era of smartphones, it would now be handy for satellite phones to be capable of synching with the regular Samsung or iPhone phone. If that is so, many apps will remain unworkable.

As you might already know, the weather in the ocean is frequently variable. This is the reason why investing in a premium quality satellite phone that offers the latest weather-related updates is crucial.

Other Important Factors to Consider


What is a satellite phone for boat?

Satellite phones largely depend on a network of satellites that are either fixed in Low Earth Orbit or Equator that’s anywhere from 500 to a thousand miles above the earth. These devices are barely affected by raging storms and, relying on the architecture of their system; they work virtually in any locations globally.

The devices are commonly lightweight and might be roughly the same size as a mobile phone. Fundamentally, having a sat phone could be a lifesaver even when your ship or yacht is furnished with other electronics. This device allows you to stay in touch with everyone wherever you are in the world.

How does it work?

Sat phones for boats work by directly transmitting radio signals to a satellite that afterwards dispatches back down to earth where a station would forward the call to the public switched telephone network.

Please be guided that the outbound calls are transmitted from the sat phone on the ground to the other satellites that is not beyond the line of sight.

Then, the next call is passed on from one satellite to another wherein it reaches the suitable sat to link back down to the correct ground station. From there, the call is delivered to the Internet or public voice network when it hits the recipient.

What are the different types of satellite phones for boat?

Geostationary Satellites

These are installed in a geostationary orbit at a fixed position in the sky. Such devices can sustain close by continuous universal coverage that comes with merely three up to four satellites, so it helps minimize the launch costs.

These satellites utilized for such systems are quite bulky and pricey to build and launch. The satellites sit at a total of 35,786 kilometres in altitude; however, an evident delay exists while making calls or utilizing data services due to the remote distance from users.

It is worth noting that the bandwidth amount on such systems is substantially higher as compared to Low Earth Orbit systems- all the three active systems offer compact satellite internet that utilizes laptop-sized terminals that come with speeds between 60 and 512 kbps.

These sat phones are practical to be utilized only at lower latitudes; in general, between 70 degrees north of the equator and 70 degrees south of the equator. Moreover, the line of sight between the satellite and phone tends to be severely affected by hindrances like forest and steep hills. Hence, signal interference is expected.

Low Earth Orbit

These satellite phones help provide users with global wireless coverage without any gaps. They orbit the earth in more superior speeds, with an altitude of 400 up to 700 miles, low-altitude orbits that come with an orbital period of 70 by up to 100 minutes.

Additionally, because the satellites are not geostationary, they maneuver towards the ground. The call must be handed off electronically to the other satellites when users pass further than the local scope since the given sat is solely in view of a phone for a short period.

Relying on the terminal and satellite positions, a workable pass of a LEO sat would commonly last roughly four up to fifteen minutes. A minimum of 1 satellite must come with a line of sight to each coverage spot at all times to ensure the coverage. Hence, a constellation of the satellites, which is usually 40 up to 70 is needed to sustain global coverage.

Why do you need a satellite phone for boat? (Benefits)

There are plenty of perks in having a satellite phone for boats, and a few of these include:

  • These devices can keep you and your loved ones in touch during emergencies and diverse sorts of disasters, especially if you are living or frequently travelling to earthquake or hurricane-prone areas. Relying on laptops, smartphones or landline phones alone is not specifically enough in unfortunate situations like these.
  • This device provides much broader coverage as compared to a regular phone. With a sat phone, it is unnecessary to be troubled about looking for signals just to make calls and send messages. You can stay right where you are and get in touch with everyone.
  • A sat phone gives your family and friends the peace of mind whenever you sail or tour around remote and unfamiliar places because they can get monitored on the progress of your journey and they could reach out to you more easily.

Connecting users with the outside world when terrestrial-based networks break down is no longer a serious problem to deal with nowadays. Mobile networks could be unavailable and fragile for different reasons.
