StealthRay™

In-Motion Satellite Communications

PRODUCT DESCRIPTION:

The StealthRay™ is a breakthrough in two-way satellite communication. The StealthRay’s™ low profile (5.9”), array antenna system is designed to provide communications for vehicles on-the-move. The innovative antenna system automatically searches for and acquires the designated satellite signal and maintains pointing via automatic tracking and control of the azimuth, elevation and polarization angles while the vehicle is in motion.

The StealthRay™ offers valuable utility across a wide range of applications, including emergency communications, since it can provide public safety authorities and first responders with a high-speed satellite communications link to moving vehicles independent of terrestrial infrastructures that are susceptible to local service interruptions, natural disasters and sabotage. Since it does not rely on terrestrial networks, it also offers applications for industries typically operating across remote geographic areas unserved by wireless carriers as well as military operations. Those industries most notably include energy, natural resources, transportation and conservation.

SYSTEM COMPONENTS:

The StealthRay™ consists of a low-profile, vehicle roof-mounted array antenna connected to a controller and a satellite modem inside the vehicle.

The roof mounted antenna includes the BUC (Block Up Converter) and the LNB. The controller supplies the power to the antenna and controls the antenna movements.

Additional networking equipment such as a router, Wi-Fi access point, as well as encryption systems are optional for creating a mobile, secure, in-motion hotspot.

SYSTEM OPERATION:

􀂃 No manual pointing is required

Using GPS signals to determine its location, the StealthRay™ automatically acquires and tracks the satellite.

􀂃 On-the-move automatic re-peaking


45.3”L 35.4”W 5.9”H

Built-in gyros allow fast recovery from line-of-sight blockages. The antenna uses a hybrid mechanical and electronic scanning process to maintain pointing accuracy.

􀂃 Adjacent satellite interference protection

In the event the antenna pointing is off by more than 0.5 degrees, the return link transmission is automatically muted until the pointing error is corrected by the antenna’s sophisticated tracking system.

􀂃 Modem compatibility

The StealthRay™ system is modem agnostic and will support all RaySat authorized SCPC satellite modems and VSATs.

CABLING:

The roof mounted antenna is connected with three cables to the controller and modem within the vehicle:

􀂃 Two RJ-58 cables using F-type connectors connect the antenna to the satellite modem (transmit signal and receive signal).

􀂃 One RJ-58 control cable using TNC connectors connects the antenna to the controller (for DC power and control data).

APPLICATIONS:

􀂃 High-speed Com-on-the-Move (COTM) for military vehicles and operations

􀂃 Emergency communications for federal, state and local first responders

􀂃 High-speed communications for trains and other commercial enterprise customers

􀂃 High-speed Internet access for moving vehicles such as motor-homes, buses, vans and SUV’s
