The SeaTel Advantage
30 years ago, RJ Matthews designed a low cost stabilized satellite antenna for use on ships, which he called “SeaTel”, and set off a shipboard communications revolution. HF radio was replaced with a satellite antenna, Cruise ships began to offer TV at Sea, The US Navy established “at sea” crew telephone call centers, and ten years later SeaTel ruled the seas with over 80% of the maritime satellite market.
In answer to the growing demand for trained Electronic Technicians, SeaTel built a large Dealer Network comprised of nearly 500 companies with over 8,000 factory trained and certified Engineers and Electronic Technicians worldwide. Ask any large ship fleet operator, such as the US Navy or Carnival Cruise why they often select SeaTel over all other commercial antennas and they consistently report that it is because of the responsive global Dealer Network, availability of spare parts and long term supportability.
SeaTel has continually reinvented the shipboard satellite industry by incorporating new technology and adapting quickly to the advances in satellite technology. Today, the SeaTel stabilized platform remains the industry De facto standard for shipboard satellite antennas. The saying “Imitation is the highest form of Flattery” certainly applies to SeaTel with numerous copy cats that have come and gone over the years.
Knockoffs might be cheaper up front, but after 29 years as a SeaTel Technician and 18 years as a SeaTel Dealer, I know that successful fleet operators tend to take the longer view. Customers know that with SeaTel you get long term commitment with spare parts availability supported by thousands of factory certified Technicians. MIL-SAT sells only SeaTel antennas for a reason. -Comments written by Don Richardson, MIL-SAT President
Look to the Leader. Look to Sea Tel!
Sea Tel ST94 Satellite TV is a reliable, intelligent TV-at-Sea system, packed with electronic innovation. It continuously calculates position, orientation and velocity for smart, seamless satellite TV for offshore applications where space is at a premium. The system’s advanced electronics enhance system awareness – including LED indicators for troubleshooting, USB port for BlueTooth adaptor and digital control interface between the motor driver and PCU for improved communications whilst high-accuracy accelerometers enhance positioning for a better service.
Sea Tel ST94 Satellite TV supports any number of satellite receivers so many TVs can be installed and individually programmed for the enjoyment of everyone on board.Crew and passengers can enjoy digital TV and music programming from leading providers in some of the world’s most remote waters, so by installing Sea Tel ST94 Satellite TV you can enhance crew welfare and increase passenger satisfaction when operating deep offshore.
The micro-electromechanical (MEM) sensors used in Sea Tel’s antennas are based on the same technology currently being used in missile and aerospace technology around the world. This high-end quality in combination with our unmatched satellite TV manufacturing experience ensures you can count on Sea Tel ST94 Satellite TV to keep working in any conditions.
The 9711 products are the next evolution in C-band systems from Sea Tel. Based on their leading 9797B product line, the new 9711 series has an enhanced feature set delivering a truly revolutionary product range.
The standard features found on all systems in the 9711 range are:
- Circular/Linear selectable feed: Allows for electronic switching from circular A Pol to B Pol, from circular to linear horizontal and vertical from Below Decks.
- Generation 2 Electronics: This electronics is the same used on our XX09 and XX10 series antennas and contains the following features:
- Internal level cage.
- Internal 400 MHz modems.
- Motor Driver assembly with diagnostic tools.
- Bluetooth connection capability from below decks to above decks equipment. Bluetooth device required.
- Added software features: All C-band feed switching can be accomplished using the DAC front panel, the Sea Tel GUI, or diagnostic software such as DacRemP and Progterm.
- Fully compatible with OpenAmip and ABS.
- Will include Standard C-band and Ku band only systems.
- No longer a need to change a feed to go from circular to linear C-band operation
The Sea Tel Model ST144 is the top-of the-line TV-at-Sea™ system. It has always been the choice for the user who needs the largest possible offshore operating area and compatibility with all known and planned satellites. With the major tracking, reliability and stability improvements introduced recently, it is more than ever the antenna system of choice.Available in C-band and Ku-band configurations or “dual-band” configuration that permits the same antenna to be used for both.
The ST144 is designed and built to pass the U.S. Navy’s tests for vibration, shock and protection against RFI and EMI emissions. And when it comes to vibration, this antenna actually exceeds Navy MIL-STD-167-1 standards.
The DAC-97 is housed in a standard 19-inch rack mount enclosure. The front panel contains a row of function keys used to select the desired information to be displayed and an array of numeric data entry keys for changing parameters or commanding the antenna functions. Data is displayed on a bright 40 character Vacuum Fluorescent display making it easy to read in all ambient light conditions. The DAC-97 can be mounted on chassis slides allowing easy access to all internal electronics. All external connections are brought out through three D-Subminiature connectors mounted on the rear panel. Flexible ribbon cable extends these connections to a terminal-mounting strip mounted on the rear of the rack enclosure separating the ship wiring from the Antenna Control Unit.
The DAC-03 Antenna Control Unit (ACU) communicates via an RS422 serial data link with the Pedestal Control Unit (PCU) located on the antenna. For unlimited azimuth pedestals, the RS422 link is coupled to the PCU via RF Multiplexers and is conducted across one of the ADE/BDE coaxial cables. The Pedestal Control Unit stabilizes the antenna against the ship’s roll, pitch, and turning motions. The DAC-03 ACU is the operator interface to the PCU and provides the user with a choice of positioning commands to point the antenna, search commands to find the satellite signal and tracking functions to maintain optimum pointing
The DAC-2200 ACU has been designed and manufactured so as to be inherently reliable, easy to maintain, and simple to operate. Except for start-ups, or when changing to operate with different transponders or satellites, the equipment essentially permits unattended operation. The DAC-2200 is housed in a standard 19-inch rack mount enclosure. The front panel contains function keys used to select the desired information to be displayed, and/or changed. Data is displayed on a 2 line 20 character display. All external connections are brought out through connectors mounted on the rear panel. Two flexible ribbon cable connections to a terminal-mounting strip mounted on the rear of the rack enclosure separating the ship wiring from the Antenna Control Unit.
The DAC-2202/2302 Antenna Control Unit has been designed and manufactured so as to be inherently reliable, easy to maintain, and simple to operate. Except for start-ups, or changing operation with different transponders or satellites, the equipment essentially permits unattended operation. The DAC-2202 is housed in a standard 19 x 1.75 rack mount enclosure. The front panel contains function keys used to select the desired information to be displayed, and/or changed. Data is displayed on a 2 line 20 character display. All external connections are made through connectors mounted on the rear panel. The DAC-2202 automatically calculates the Elevation, Azimuth and Polarization pointing angles based on the ships Latitude, Longitude and the desired Satellite Longitude position. A programmable pattern search will automatically scan the area for a desired satellite if no signal is found. These two features make locating a new satellite very easy. The DAC-2202 requires satellite signal input to its internal Satellite ID Tracking Receiver to keep the antenna peaked on satellite. This internal receiver is a DVB compliant DSS compatible Satellite Identification receiver. Its input allows full coverage wide L-Band (950 to 2150 MHz) for tracking video transponders in all TVRO satellites and may be set to Single Channel Per Carrier (SCPC), or Narrow Band IF (NBIF) mode to allow tracking an L-BAND satellite beacon or narrow band data carrier.
With its extended web based secured user interface and built-in remote management capabilities, MIL-SAT offers integration into network management systems through its built-in Media Xchange Point (MXP).
