NETA MRA45

Marinesat is an in-motion satellite antenna especially designed for boats, yachts and ships. The radome includes a motorized cassegrain antenna. When started, the system searches for satellite, finds and then tracks it by using its gyroscopes and microprocessor-controlled motors. The integrated GPS system enables the antenna to automatically detect its exact current position and then calculate the correct LNB angle required for the satellite. No user intervention is needed even if a different satellite is selected or the location of the antenna is changed. The system makes all necessary adjustments automatically. The control box enables the antenna to receive 16 different satellites. The antenna can be controlled with the control box unit provided with the system. Optionally the control box also functions as an HD satellite receiver. A common interface makes it possible to receive scrambled channels. The multi-output option can be used to distribute signals to different locations.

Overview

MRA45 maritime satellite antenna is compact yet high-performance system suitable for boats up to 30 feet.

The cassegrain antenna receives signals from most of the satellites inside coverage area. With the integrated GPS, the antenna can adjust its LNB skew angle automatically. The antenna can receive upto 16 different satellites.

Dynamic Skew option is a feature controlling skew angle dynamically with the help of a third gyroscope so that it performs as third axis control. It provides stabilised skew angle so that the antenna can work in wavy sea conditions as well.
SIS is Satellite Identification System, it comes as a standard feature to identify the satellite with "Digital Satellite Signal Processor" by analyzing the satellite data.
