Spaceflight Now is live at the Cape Canaveral Air Force Launch Site covering the MUOS-1 launch aboard the Atlas 5 vehicle which will happen at 5:15PM EST (2215UTC). Here is the direct LIVE-STREAM link.Shortwave America will be live blogging this event since it is related to a rather important communications satellite system.? MUOS is the acronym for MOBILE USER OBJECTIVE SYSTEM.
What MUOS is and what is does, from the following source:
Description:
Mobile User Object System (MUOS) is a narrowband Military Satellite Communications (MILSATCOM) system that supports a worldwide, multi-Service population of mobile and fixed-site terminal users in the Ultra High Frequency (UHF) band, providing increased communications capabilities to smaller terminals while still supporting interoperability to legacy terminals.
?
Features:
MUOS adapts a commercial third generation Wideband Code Division Multiple Access (WCDMA) cellular phone network architecture and combines it with geosynchronous satellites (in place of cell towers) to provide a new and more capable UHF MILSATCOM system. The constellation of four operational satellites and ground network control will provide greater than 10 times the system capacity of the current UHF Follow-On (UFO) constellation.
MUOS includes the satellite constellation, a ground control and network management system, and a new waveform for user terminals. The space portion is comprised of a constellation of four geosynchronous satellites, plus one on-orbit spare. The ground system includes the transport, network management, satellite control, and associated infrastructure to both fly the satellites and manage the user?s communications. MUOS and these newer terminals are designed to support users that require greater mobility, higher data rates, and improved operation availability. The new waveform is termed the MUOS Common Air Interface (CAI), a Software Communications Architecture compliant modulations technique for the Joint Tactical Radio System (JTRS) terminals. The MUOS CAI waveform will be available to the Services for porting to JTRS terminals in late 2008. The first MUOS satellite is scheduled to provide an On-Orbit Capability in March 2010. MUOS achieves Full Operational Capability in 2014.
