C2SAT Introduces New Stabilised 4 Axes VSAT Antenna
Washington DC (SPX) Feb 22, 2007 C2SAT has introduced its new Stabilised 4 Axes1.2 m VSAT antenna. The new antenna constitutes the first product in a series of stabilised satellite terminals based on the same mechanical rig, where the high performance inherent to the patented design produces a competitive edge for a range of transponder frequencies and satellite dish sizes. Best-in-Class Accuracy When in motion, the system achieves superbly high 0.1 dB satellite tracking accuracy, which is comparable to a terrestrial satellite antenna. The high tracking accuracy is a result of the system's gradient tracking method, a predetermination tracking parameter and the 4 Axes design, where the fourth axis refers to the cross-level elevation. Higher accuracy results in improved availability, more efficient use of shared lines and network bandwidth, lower transmission power, and wider operational area in the satellite footprint. It also permits equally perfect communication whilst operating under severe and harsh conditions. Fast and More Robust System The system is faster due to the gimbal design with AC servo motors on each axis, and the gradiant satellite tracking method on all 4 axes. Where competing systems need minutes, the system locks on the satellite within 6 sec acquisition time, starting from its parking position. This also speeds up the transition from one satellite to another and results in extremely fast recovery time. Because the gimbal design excludes the balancing counter-weights usually necessary in centre pole-based systems, the servo motors on the axes are subjected to less torque. This also leads to lower stress on the mechanical rig. The construction is ruggedized and designed to meet U.S. MIL-standards, including shock, vibration and EMC. Always On Other maritime systems commonly experience sync losses, down-times and restarts when a vessel rolls back and forth and the satellite is located in zenith, or when an object such as a ship's mast or a dense thunder cloud interferes with the signal-based satellite tracking method. C2SAT's 4 axes design combined with the predetermination tracking parameter keeps the antenna targeted at the satellite at all times, whether or not the satellite is in line of sight. This is key in providing truly reliable Satcom services that are "always on, not almost always on". "In addition to the superior performance of the system, customers wanting to simplify the service and maintenance endorse our modular approach and easily accessible construction" says Fredrik Hanell, CEO of C2SAT. "The system has proven itself in customer tests and trials, and judging from the commercial response we get it clearly fulfils a previously unsatisfied need in the market." The system is now commercially available.
