US Navy Launches MUOS Satellite

This array allows mobile forces, including submarines, surface ships and aircraft, to communicate around the world via the narrowband spectrum.User communities that will primarily benefit include ground forces at the individual soldier level but also include members of all services and special forces.“The legacy satellite communication system allowed users to ‘talk’ as long as they were within the same satellite footprint,” explained Navy Capt. Joe Kan, program manager for the Communications Satellite Program Office. “MUOS allows troops all over the world to talk, text and share mission data seamlessly without having to worry about where they are in relation to a satellite.”The program office falls under the Navy’s Program Executive Office for Space Systems, which has responsibility for the MUOS program and is located at the Space and Naval Warfare Systems Command in San Diego.The Internet Protocol-based nature of MUOS allows network access to classified and unclassified networks. This network access for deployed tactical users will allow the exchange of critical situation awareness and targeting information.“With the launch of MUOS-4 we’re going to deliver that worldwide coverage and communication service for users,” explained Nina Tran, the program office’s space division director. “The legacy payload we have on MUOS satellites allows a smooth transition to a newer, better MUOS capability. We are benefitting from providing the legacy channels for current users and we are exploring all the capability that MUOS has to offer.”MUOS is an architecture comprised of a five-satellite constellation – a fifth on-orbit spare to be launched in 2016 – four ground stations across the globe, complex software to manage the network and an integrated waveform for use with user radios.According to the program office’s technical director, Jim Parsons, it’s the system’s flexible design that allows rapid insertion of technology to keep the system up-to-speed.“The nice thing about MUOS is that the ground system and terminals contain all the switching and routing technology,” Parsons said. “The satellite remains unchanged over time and can allow technology insertion into the ground stations and the waveform over time to increase capability without having to make any satellite changes.”Cmdr. Pete Sheehy, principal assistant program manager, explained that 24/7, beyond-line-of-sight communications will greatly benefit ground forces needing aviation support.MUOS is already providing legacy communications to combatant commanders via active satellites on-orbit. MUOS’ advanced capability – Wideband Code Division Multiple Access – has been demonstrated in various environments, platforms and applications such as integration testing with the newest submarine antennas, Navy special operations scenario exercises and Air Force C-17 in-flight tests.“In our testing we’ve tried to be as realistic as possible,” said Jarratt Mowery, director of end-to-end system testing. “In several events we’ve brought uniformed warfighters in and given them training on the MUOS system and operating its components. They were able to define the types of operations they would like to use the system and allowed them to exercise those operations in a realistic environment. Be that in vehicles driving around, in a forest with a thick canopy or even in airborne platforms.”An added benefit beyond the system’s initial requirements is extending communications further north and south toward the polar regions. This polar coverage, up to approximately 85 degrees in the Arctic under peak conditions, is significant considering that wireless and satellite communications has always been a struggle at extreme north and south latitudes.Over the next several days MUOS-4 will transition to reach its geosynchronous orbit location approximately 22,000 miles above Earth to begin initial on-orbit testing. The satellite’s solar arrays and antennas will then be deployed. On-orbit testing will start for subsequent turn-over to the Navy for test and commissioning to service.Two MUOS satellites, launched in 2012 and 2013, are already providing legacy communications capability from their geosynchronous orbits over the Pacific Ocean and the United States.MUOS-3, launched in January, was accepted by the Navy in June after on-orbit testing. The third satellite is awaiting final testing before being accepted for operational use.Ultimately, the constellation and associated network will extend narrowband communications availability well past 2025.The Navy’s Program Executive Office for Space Systems, located at the Space and Naval Warfare Systems Command in San Diego, is responsible for the MUOS program.Image: US Navy Equipment & technology Share this articlelast_img read more

Missing Bean needs major hygiene improvements, says FSA

first_imgThe Missing Bean, the popular coffee shop on Turl Street, has received a food hygiene rating calling for “major improvements” from the Food Standards Agency.The food hygiene rating is a system managed by the Food Standards Agency (FSA), a government body which awards ratings out of five for “standards of food hygiene found on the date of inspection”. It indicates that any organisations receiving a rating of two or fewer require improvement: The Missing Bean received one out of five. The inspection took place in November 2013.When asked by Cherwell, the FSA commented that a rating of one out of five would be awarded for a wide range of problems, from “evidence of widespread pest infestation” to “inadequate temperature control for high-risk foods. ”However, The Missing Bean stressed that its problems were of a different nature. According to the owner, “the rating of one star is because of the state of the building and doesn’t concern the food side.” The coffee shop also noted that improvements, such as fixing the walls in the basement, have been made since the inspection, and claims that the FSA, “has said that once [they]have made the changes it can guarantee a four or five star rating.”The FSA is a non-ministerial government body which was established in 2001 to protect public health. It rates every company selling food in England, Wales and Northern Ireland.Student reaction to the FSA’s report on The Missing Bean has been mixed. One frequenter of The Bean expressed disapproval, commenting, “Frankly I’m disturbed – I visit The Bean regularly and I’ve always thought that it was clean and hygienic, but I don’t think I’ll be going as often until it improves.”Yet despite some concerns, many students were less worried. Unfazed by the FSA’s verdict, one Pembroke third year observed that, “the best coffee comes from digested animal waste… so long as their coffee continues to be delicious, I wouldn’t care if they were cycling it through their own digestive tracts.”Thomas Cranshaw, a Lincoln medic, expressed his surprise at the rating. He said, “I’ve always found the Bean to be clean and hygienic. I’ve never had any problems with any of my food from there, nor heard of anyone else getting ill… It’d be good if they improved it but this won’t be altering my Beaning habits.”Oxford has a large number of institutions that score poorly with the FSA. According to its website,132 businesses in Oxford City have a rating of two or less, meaning that over one in ten food vendors have been told to improve hygiene standards.In the last year, other organisations given a rating of one out of five included Oxford Rendezvous, the Organic Deli, and Freud’s in Jericho.Arzoo was given a rating of zero, meaning “urgent improvement necessary” in a report from October 2012.last_img read more

This home at Upper Caboolture offers a serene tropical retreat
