Signal analyzers to install Maritime Internet. How does the Internet work in the sea?

July 2, 2019.

Holiday cruises (and most boats in general) mount motorized satellite antennas that are constantly aligned with the telecommunications satellites. Through these satellite dishes, all kinds of telecommunications are sent and received: Internet, telephony, television and data.

Did you know?
Maritime Internet has always been focused on pleasure boats (yachts, cruises and ocean liners). Nowadays prices are much more affordable so that even small fishing vessels have access to the Net: It is demonstrated it improves the work environment and it increases productivity because it is possible to find out via Internet from the fish market the state of the fish auctions.

Maritime Internet systems

Measurement and analysis equipment to install maritime Internet

RANGER Neo TV and Spectrum analyzers are compatible with the most popular communication protocols DiSEqC, SatCR (SCD/EN50494) and JESS (SCD2/EN50607). They are perfect for field work because they are shock protected and they feature more than four hours of battery operation time.

Analyzers for mounting and setting up maritime antennas, and to certify the appropriate operation of their guiding motors
PROMAX analyzers are the perfect tool to use in tasks of mounting and setting up maritime antennas, as well as to certify the appropriate operation of their guiding motors.

After installing the antenna, PROMAX analyzers also can certify the proper reception of the television signal in all the cabins because they are packed with many functions to locate and diagnose errors in the wiring and the headend equipment. No matter if it is RF television reception, IPTV or even to diagnose problems in the WiFi communications for the onboard Internet services.


How do the stabilized maritime antennas work?

Satellite communications maritime antennas are mounted on a motorized structure that allows its automatic movement along three axes to compensate the yaw, pitch and roll of the vessel.

  • The system is guided by an Antenna Control Unit (ACU) that must know the orbital position of the satellite (or satellites) that it must be pointed to.
  • The ACU carries out a continuous tracking of the geographic location of the satellite and of the vessel itself thanks to a system that has a built-in GPS, inclinometers, accelerometers and a signal power meter.
  • The controller very accurately drives the motors of the antenna, thus permanently pointing it to the satellite even in the worst conditions like a storm.

Does it look familiar to you? The concept of a stabilized system is not new: Nature has been ahead of the technology for thousands of years ago.
