Broadband at Sea - VSAT


 Sea Tel 9797B VSAT is a high performance, dual-band selectable C and Ku-Band system that uses Radical Offset antenna technology. It offers complete flexibility and superb efficiency, with high throughput and service availability for connectivity whatever the weather or the sea conditions. Regardless of where you operate, you can be sure of always-on broadband, giving you access to a wealth of communications, including business and crew centric email and web connectivity, in addition to high-end IP applications such as vessel monitoring or drilling software.

An unmatched range of powerhouse features results in straightforward installation, maintenance and operation. The antenna can be accessed remotely for trouble shooting and can be configured as a dual antenna solution when using an arbitrator. Sea Tel 9797B VSAT is both INTELSAT and DSCS compliant so you get more throughput using the same or even less valuable deck space. It utilises the advanced 19" rack mount DAC 2202 Antenna Control Unit, which offers all ports and connections needed to set up and operate complex on board communication networks.

Cobham SATCOM antennas are designed and built to exacting standards. They develop and integrate innovative, cutting-edge technology to ensure high performance and reliability in the maritime arena, resulting in hardware that service providers and end-users can trust. It isolates the antenna from the ship's motion no matter how extreme the weather  and rough the seas. The antenna system responds to ship's movement at a rate as fast as 90 degrees per second ensuring accurate pointing and therefore a stable connection 24/7. Because it is one of the most powerful and efficient C-band antennas on the market, Sea Tel 9797B VSAT is used in a variety of diverse maritime and offshore situations, all of which demand high-throughput and reliable connectivity for critical applications. Platforms, OSVs, ferries and cruise ships all use Sea Tel 9797B VSAT antennas as a way to guarantee everything from connectivity for technical applications and operational collaboration to supporting on-board retail and ensuring multiple-user connectivity for passengers and crew. Sea Tel 9797B VSAT is fully approved for Naval vessel installation and meets MIL-STD-167 specifications for shock and vibration, Navy MIL-STD-901D Grade B shock standards and MIL-STD-461 EMI & RFI standards (including 200V/M). It is also available in an X-band version. All Cobham SATCOM VSAT antennas are designed and built to exacting standards, ensuring their suitability for the harsh maritime environment. In any conditions or operational environment, you can count on the quality of design, components and manufacturing, and benefit from a reliable link at all times.

Cobham SATCOM has developed a switchable feed kit that introduces a new capabilities for Sea Tel 9797 VSAT antenna. The kit is upgrade that would need to be installed by an engineer on existing antenna. Once installed, the Sea Tel 971MA switchable feed upgrade would allow the user to transfer almost instanly between C-band and Ku- Band, at the touch of a button. The Sea Tel 971MA kit adds a permanently installed Ku-band radio frequency feed along with a moveable sub- reflector . It eliminates the need to manually change feeds and rebalance the antenna by fully automating the transitioning process. This solution will provide significant cost savings during the lifetime of the antenna, while increasing the amount of opportunities when the switching capability can be implemented to ensure availability of VSAT services. Switching between bands provides more redundancy in satellite communications and greater flexibility for the user. It is particularly useful in regions of high precipitation, such as tropical areas of the Arctic when the performace of ku- band services is affected by the rain fade phenomenom.
