Rugged Military Version:




Rugged Military Version:

IntegraSys has announced a new military version for its Satellite Terminal Line-up Tool based on Itronix rugged PDA model Q100, specifically built to operate under demanding environmental conditions in the battle field. Military VSAT communications deployment and installation will benefit from this new rugged platform addition to the SatMotion Pocket System supported hardware, ensuring MIL-STD 810 F environmental specifications accomplishment.The system simplifies and speeds up VSAT installation and commissioning providing a pocket tool to perform the line-up and cross polarization isolation adjustment on the uplinked carrier transmitted by the VSAT. The rugged PDA acts as a remote graphics terminal to display in real-time polar and cross-polar information obtained from a spectrum analyzer located at the Operations Control Center. " SatMotion Pocket uses either a wired or Wi-Fi connection to the VSAT to provide high speed remote access to the remote monitoring spectrum analyzer preventing the need to use extensive instrumentation equipment ". Users are connected to the Operations Control Center via IP and access the monitoring spectrum analyzer’s trace information on the PDA screen in real time. Several commercial spectrum analyzer models from the main instrument manufacturers are supported by the system. To avoid control center coordination, the system includes a carrier monitoring server computer and software to interface remote PDA users to the monitoring instrumentation. This server adds concurrent multi-user support, so one single monitoring analyzer can support multiple simultaneous line-ups. " Using standard Wi-Fi speed, up to ten different concurrent users per instrument will obtain one analyzer trace per second update rate, each using its own analyzer set-up.

Comtech EF Data Introduces New L-Band Satellite Modem:

Comtech EF Data Corp., a subsidiary of Comtech Telecommunications Corp. (NASDAQ: CMTL), announced the release of the CLM-9600L Satellite Modem. This advanced, high performance L-Band satellite modem is ideally suited for military applications, offering variable data rates from 2.4 kbps to 20 Mbps, providing high-level modulation techniques, operating with an array of forward error correction codecs and supporting OM-73 plus other scrambling methods.


CLM-9600L Satellite Modem:

The CLM-9600L Satellite Modem provides the industry’s most bandwidth efficient forward error correction and modulation. By deploying the optional Turbo Product Coding (TPC), the inherent decoding delay is significantly reduced, enabling optimization on even marginal satellite links. Comtech EF Data’s TPC also offers increased coding gain, lower decoding delay plus significant bandwidth savings. Other forward error correction options for the CLM-9600L are Viterbi, Sequential and Reed-Solomon. Featured modulation techniques are Phase Shift Keying (PSK) and Quadrature Amplitude Modulation (QAM), specifically, 8-PSK, BPSK, QPSK, OQPSK and 16-QAM. Management of the CLM-9600L can be done both locally or remotely. The modem can be configured and monitored from the front panel featuring a Vacuum Florescent Display (VFD), a keypad and eight LED indicators, or through the remote Monitor and Control port. And, in closed network configurations, a special feature can be utilized to control the distant end of a satellite link using a Comtech EF Data proprietary overhead channel, called Embedded Distant-End Monitor and Control (EDMAC). The EDMAC mode is transparent to the user and requires no additional equipment or cabling. For further advanced control of the remote end, the Automatic Uplink Power Control (AUPC) feature can be used in conjunction with EDMAC, enabling the modem to automatically adjust its output power to maintain the Eb/No of the remote end of the satellite link constant for protection against rain fading.

Bit Syncs Optimized to Meet the Specific Needs of the Satellite Downlink. 720 MHz IF X-Band Converter tuned in 16 Hz Steps over the entire 8000 to 8500 MHz frequency band supports all existing and currently planned earth resource satellites.


DTH DISTRIBUTION SYSTEM:

The month of August has seen DTH fever catch on, in the Indian market. Even though the much anticipated, official DTH launch by Doordarshan was not announced, transmissions have commenced. Subhash Chandra's Dish TV has also increased programming to 96 DTH channels. With DISH TV being marketed in urban centres also, there is a large demand from housing societies, hotels, hospitals and other urban customers in multiple dwelling units for DTH installation. A basic DTH installation - such as that typically installed in India, requires each customer to install his own Dish antenna, LNBF and digital satellite receiver. Besides the large duplication of dish antennas and KU band LNBFs, it is also often not physically possible to install these multiple units on the terrace of a large building. Identifying this need, Raju & Raju have launched, for the first time in India, "Universal DTH Distribution Amplifiers". Each amplifier accepts C or Ku band signals from upto 4 separate LNBs or a single LNBF. Hence simultaneous inputs from both Dish TV and Doordarshan's DTH can be fed in, still leaving a facility to include the TATA-STAR DTH signals when the service commences. The amplifier also accepts any RF input (48 MHz to 860 MHz) from a terrestrial antenna or VCR, VCD or DVD. The Universal DTH Distribution Amplifier amplifies each of these signals and provides 8 equal outputs. Each output can feed a separate residential unit, hotel or hospital room, etc.
