COVERAGE
The service is available in Europe on all the Mediterranean, in the Middle East, the Caribbean, in Latin America, the United States, the Far East and in other parts of the world.

Worldwide coverage is guaranteed through various satellite operators:

EUTELSAT, HELLASAT, AMOS PANAMSAT, INTELSAT, etc.

For details, see the FOOTPRINT map of the various satellite systems available on request.

THE MOST COMPACT SYSTEMS IN THE WORLD
The diameters of V-SAT Navisystem systems are approximately 50% smaller than the conventional systems. In terms of volume, this is very significant for boats where space is limited.

V-SAT 65 HT: 65 cm dish, 72 cm radome diameter
V-SAT 75 HT: 71 cm dish, 81 cm radome diameter
V-SAT 85 HT: 82 cm dish, 92 cm radome diameter
V-SAT 95 HT: 96 cm dish,104 cm radome diameter
V-SAT 120 HT: 117 cm dish, 130 cm radome diameter
V-SAT 135 HT: 135 cm dish, 145 cm radome diameter
V-SAT 150 HT: 150 cm dish, 170 cm di radome diameter
   

FEATURES
The Navisystem technology is a service that is always active (ALWAYS-ON) with an UP-LINK speed up to 10 MBps. This allows simultaneous data transmission operations, telephony, fax, video-conferencing, GSM, e-mail, video and weather for a number of variable operators.

This series of stabilised V-SAT antennas are also available for heavy use. Many speed combinations UP/DOWN are available.

COST EFFICIENCY
Navisystem’s V-SAT innovative technology offers a significant reduction of costs compared to other systems with similar services. The broadband satellite solution provides internet connectivity and telephone network (PSTN) at a fixed monthly cost, and a GSM service during sea voyages and offers unlimited data transfer.

APPLICATIONS
All types of boats that require a dlwais on-line broadband satellite system.

The service is also available for private networks including files and video transfers such as videoconferencing. The V-SAT is an excellent solution for cruise and merchant ships, oil tankers and vessels of every type.

Yachts and mega yachts can also use this technology.

TECHNICAL FEATURES

 System of polarization on 3-axis control most active Polarization automatic (4th axis).
Exclusive use of high performance optical Cassegrain prime focus valid for all models.
Feed system: KU-BUC - OMT - FILTER and LNB bands are installed behind the dish. This allows the optimisation of the signal/noise ratio.
Automatic polarisation with continuous control for the correct alignment with the satellite.
Optimisation of the tracking with the combination of gyroscopes on three axes and gyrocompass.
Fast installation with the use of special Plug and Play connectors.
Monitor availability to control the spectrum of the band received.
GPS NMEA 183 output for direct connection to the satellite modem.
Cross - Polarisation TX - RX > 30 dB.
Noise figure of the LNB 0.3 - 0.7 dB.
RF transmitter x 2 W (more powerful systems can also be used).
Average power required 100 or 220 V AC 50/60 Hz, 75 W for 65 VS3 - 75 VS3 and 100 W for 85 Vs3, 150 W for 120 VS3 - 135 VS3, 175 W for 150 VS3.
Easy maintenance.
GPS already installed on the antenna.
Input gyrocompass: NMEA 183 HEHDT sentence (10 data per second).
Possibility to work with satellites in every part of the world.
Gyrostabilised platform for all systems.
Polarisation in RX and TX H/V and circular (where required).

ASSISTANCE
Navisystem stabilised antennas are designed to work during many years without assistance. In case of repair, the technicians have easy access to the system.

The electronic cards are protected from salt water, shielded and earthed in dedicated aluminium containers. The cable connectors are well protected inside the antenna’s support.

Technical assistance service to customers is available 24/7.

CONTROL UNIT SAT 105 A
The SAT 105 A unit allows monitoring and optimising several parameters of the system. This is particularly useful when the ship or vessel is at the limit of coverage from the selected satellite.

The SAT 105 A control unit can select up to 12 satellites with a simple touch of the remote control. A series of keys allow an initial setting.

A tool for the level of the signal received shows that the satellite is correctly hooked up.

A digital display indicates all the functions of the selected satellite.

  
     
 
 
     
 
 
V-SAT 65 HT
 
 

Recommended for boats from 17 to 25 meters.

A parabolic reflector of 65 cm and a radome of only 70 cm can also ensure a service on small boats.
 
 
     
 
 
V-SAT 75 HT
 
 

Recommended for boats from 23 to 30 meters.

The V-SAT 75 HT was created to go around the world along with other large antennas.

Its features make it unique. Compact and swift, it assures a good service even during adverse weather conditions.
 
 
     
 
 
V-SAT 85 HT
 
 

Recommended for boats from 24 to 35 meters.

With the V-SAT 85 HT we are looking at an antenna with an 85 cm dish contained inside a radome with a diameter of only 92 cm.

The ideal combination between large antennas technology and small dimensions. This antenna can operate both in the United States and Europe among the possibilities offered.

It is the smallest antenna for mega yachts.


 
 
     
 
 
V-SAT 95 HT
 
 

The V-SAT 95 HT Navisystem offers an antenna capable of high level performances.

The dish always operates effectively even in difficult weather conditions thanks to its 95 cm dimension. The series of accessories with which it is possible to further equip this antenna make it a unique product in the field.
 
 
 
 
     
 
 
V-SAT 95 HT PROFESSIONAL
 
 

Recommended for mega yachts from 30 to 40 meters.

The professional version, almost identical to V-SAT 95 HT, differs with its reinforced motors, connectors for naval use, special software and more severe tests. Directed for heavier use than the standard version.

The PROFESSIONAL series is suitable for mega yachts and ships.


 
 
 
 
     
 
 
V-SAT 120 HT PROFESSIONAL
 
 

Recommended for mega yachts over 40 meters and commercial and cruise ships and other special applications.

With V-SAT 120 HT, we enter the field of products dedicated to means with which to face cruises or to transmit worldwide, having therefore to count on effective and reliable equipment in any conditions.

 
 
 
 
 
     
 
 
V-SAT 135 HT PROFESSIONAL
 
 

Recommended for mega yachts over 50 meters and commercial and cruise ships and other special uses.

It is equipped with a 135 cm dish, high efficiency motors, structures entirely in aluminium with advanced systems such as the use of lasers for cutting. It is able to secure moderate weights, and it is solid and resistant to very high vibrations despite its dimensions.

High speed data transfers are possible with this antenna either with up link or down link, impossible to reach with smaller antennas.

It can operate with C Band.
 
 
 
 
 
     
 
 
V-SAT 150 HT PROFESSIONAL
 
 

Recommended for mega yachts over 50 meters and commercial and cruise ships and other special applications.

It is equipped with a 150 cm dish, high efficiency motors, structures entirely in aluminium with advanced systems such as the use of lasers for cutting. It is able to secure moderate weights, and it is solid and resistant to very high vibrations despite its dimensions.

High speed data transfers are possible with this antenna either with up link or down link, impossible to reach with smaller antennas.

It is also available with C Band for satellite connections even when crossing the ocean.
