This technology is used to enable the VSAT system to be used on vessels roaming across multiple satellite beams, maintaining connectivity as they move through different satellite footprints.
Mitsubishi Electric’s MVA100 Maritime Ku-band VSAT antenna system is a 1-metre dish designed for 'earth station on the vessel' applications. It features a 3-axis stabilised mount built to ITU-R requirements.
The ROAM protocol offers a common management interface for Comtech EF Data’s Roaming Oceanic Satellite Server (ROSS) and third-party Antenna Control Units (ACUs) by providing a generic set of commands, information, interfaces and status queries.
ROSS is an integrated location server that works in conjunction with Comtech EF Data’s Vipersat Management System to facilitate on-the-move satellite communications for oceanic vessels.
ROSS enables remote modems to interface with stabilised, auto-tracking antennas. Vessel position data, satellite signal and management status are monitored to determine when satellite handoff is necessary.
Comtech says that, as ROSS can support different types of ACUs, the ROAM protocol can help to reduce complexity in operation by providing basic parameters required to globally roam across multiple satellite beams.
"Satellite-based communications on the high seas will be greatly enhanced for our maritime customers with the combination of our antenna system and Comtech EF Data’s market-leading technologies," commented Keizo Miyawaki, general manager for the IT space solutions division of Mitsubishi Electric.
