Nowadays people need to be connected to the internet anytime and anywhere, even on the world’s oceans and seas. Broadband is needed in vessels either for entertainment purposes or for business purposes. Internet connectivity is a vital requirement for crew retention and passenger satisfaction. This can be provided only by using satellite communications (VSAT) technology at sea, known as “Maritime VSAT.” There are various applications for Maritime VSAT which will be discussed in this blog. These applications require maintaining the connection between satellites and vessels during their movements at sea. This can be achieved by auto-acquisition and stabilized antenna systems, and the automatic switching technique that switches the traffic among VSAT beams. 

Maritime VSAT can support many types of services such as voice, video conferencing, fax, email as well as maritime surveillance and solution services, namely: 

  • Navigation 
  • Downloading electronic charts 
  • Monitoring of vessel location 
  • Transmitting information related to vessel operations 
  • Reporting finishing activities to comply with maritime and commercial regulations  

Maritime VSAT provides high speed connectivity to deliver these essential services to ships with excellent QoS. Three different frequency bands are currently used for maritime VSAT technology (Ku-Band, Ka-Band & C-Band). Each of these frequency bands has its suitable applications based on its own characteristics. The following comparison can illustrate the main differences among them:  

Item Ku-Band Ka-Band C-Band 
Frequency range 11 to 18 GHz 26 to 40 GHz 4 to 8 GHz 
Antenna Size (diameter) 0.9m to 1.8m 0.6m to 1.2m 1.8m to 3.7m 
Throughput ~10Mbps ~50Mbps ~10Mbps 
Suitable for  Small Vessels Cruise Ships Tankers or large vessels 

The question now is “Who will need such broadband services at the sea?” 

In fact, many maritime companies consider the use of broadband services at sea for their crew and passengers (such as tourists in cruise ships, fishers, sailors, engineers at oil rigs and personnel sailing tankers) as a critical component. Maritime VSAT technology can guarantee good Quality of Service (QoS) for all these applications during the vessel movement in almost any weather conditions.  

Maritime VSAT Components:

  1. Maritime VSAT components at the vessel: 

A stabilized VSAT antenna is installed on the vessel which is connected to a satellite router. This satellite router is responsible for routing the services to the LAN on the vessel, while the antenna is responsible for connecting the vessel to the global VSAT system using one of the VSAT frequency bands (C-band, Ku-band or Ka-band). 

2. Maritime VSAT components on land: 

The terrestrial landing point for maritime services is the Teleport. The teleport antenna receives the signals from the satellite. This antenna is connected to the hub system, which is subsequently connected to the internet. Due to the importance of this hub system it is usually monitored by NMS that is also responsible for controlling and configuring the maritime VSAT system. 

Maritime VSAT and Satellite Internet

Maritime VSAT Market: 

Maritime VSAT customer types vary based on the type of the reequired service. For example, government agencies need maritime VSAT to control navigation & fishing, while oil and gas companies need maritime VSAT to enhance their business by monitoring oil & gas rigs as oil and gas pipelines need to be monitored 24 hours per day and 7 days per week to guarantee the safe transmission of oil and gas through these pipelines.  

The number of ships navigating the world’s oceans is increasing rapidly due to the enhancement in world trade. This growing enhancement in trade increases maritime traffic in return. It is expected that maritime VSAT Compound Annual Growth Rate (CAGR) will reach 13 to 14% before 2021. 

Link Communications Systems provides Maritime VSAT as a leading satellite Internet provider worldwide. LCS provides service to dozens of ships in the fishing, leisure, oil & gas, and freight shipping markets utilizing antenna systems from Intellian and Cobham and Inmarsat and providing services over KU, KA, and C band. The future of the maritime VSAT market is set to grow even further as is the future of broadband communications all over the world. 

According to the latest research by the Global Small Satellite market is expected to grow from $ 2.28 billion in 2016 to reach $ 7.66 billion by 2023 with a CAGR of 18.8%. 

The satellite industry is an integral part of any economy for the development of infrastructure for government agencies and commercial companies. The growth of this segment is contributed to the increasing demand for high-resolution imaging services which is accompanied by high-speed communication services. North America accounted for largest market share followed by Asia pacific. 

The key trends of the market include increasing HD and UHD channel counts, adoption of new technologies, emerging regional operators, increased global broadband penetration, rising commercial GEO satellite orders and rising launches of Nano satellites. 

Satellite Market Growth

According to the Satellite Industries Association, Significant expansion in terms of capabilities and demand is underway in the small satellites market. Over 6,200 small satellites are expected to be launched over the next ten years, a substantial augmentation over that of the previous decade. The small satellites market from 2017-2026 will be driven by the roll-out of multiple constellations accounting for more than 70% of this total, mainly for commercial operators. 

The total market value of these small satellites could reach $30.1 billion in the next ten years, up from $8.9 billion over the previous decade.  

The small satellite market has quickly expanded over the last five years and will experience a sustained expansion in the future. Constellations’ demand is more cyclical with strong variations driven by deployment in batches whereas demand for single satellite missions is more stable. Improvements in performance also change the shape of the satellite; miniaturization is a continuous process which gives customers the choice between lighter satellites with the same capabilities or heavier, more powerful satellites. In the heaviest mass category, small satellites are now able to perform missions that in the past were only achievable by satellites heavier than 500kg. 

Satellites used for earth imagery accounted for just $2 billion of the total industry but accounted for 11 percent of the sectors growth.  

Of the total $16.5 billion manufacturing market value from 2017 to 2026, $3.7 billion is absorbed internally by in-house manufacturing; the remaining $12.8 billion is considered part of the open market. Over the period of the study (from 2007 to 2026), there is a clear divide in the typology of manufacturers of small satellites: In-house company and academia manufacturing rests in the realm of less than 50kg, while dedicated integrating companies comprise the realm of 50kg and higher. Considering the number of satellites that are being manufactured in-house or are captive to domestic manufacturers where tenders are not open to foreign bidders, the market potential for third-party industry does not comprise the entire market value. 

By end-user, commercial sector has acquired the largest market share. The growth of this segment is contributed to the increasing demand for high-resolution imaging services which is accompanied by high-speed communication services. North America accounted for largest market share followed by Asia pacific.
