Ditel V81 maritime VSAT satellite communication antenna system delivers superior tracking and RF performance, making it an ideal choice for larger vessels. Designed for easy installation and onboard operation, it also provides access to remote support when needed. Users can seamlessly enjoy remote control via PC and mobile devices, web browsing, broadband connectivity, video monitoring, video conferencing, VoIP, and other network applications, in dynamic sea conditions.
High Tracking Accuracy Adopting an upper inertial navigation scheme, an accurate error model, and efficient compensation and correction of errors, resulting in high tracking accuracy.
• Modem Compatibility Compatible with a variety of modems, including iDirect, UHP, Newtec, Gilat, Comtech, Hughes, Anovo, Spacebridge and many more.
•Open Platform Compatibility The ACU integrates the ABS function and supports the iDirect OpenAMIP protocol for auto beam switching.
• Stable and Reliable Tracking Adoption of reflector surface tracking algorithm, based on three-dimensional relationships of signal level, azimuth angle, and elevation angle, ensuring stable and reliable tracking.
• Easy Installation Both 1-cable and 3-cable solutions available for connecting the antenna to indoor units, ensuring convenient installation and simplified wiring.
•Advanced System Control The ACU has built-in Wi-Fi, allowing wireless device users to directly connect. Advanced system control and antenna status monitoring can be achieved using an ACU web interface.
