13 Aug 15. Airbus DS Communications, an entity of Airbus Defense and Space, is showcasing its upgraded VESTA™ Radio solution, a P25 Phase 2 system, with a demonstration at APCO 2015 in Washington, D.C. on August 16-19. Attendees are invited to view the demonstration at booth #1333.
“We are excited to unveil our latest upgrade to our VESTA Radio P25 solution that will offer our customers increased talking capacity while still providing fully open and compliant P25 interoperability,” said Bob Freinberg, CEO of Airbus DS Communications. “With our P25 Phase 2 system, agencies can expect enhanced and seamless call coordination between public safety officials — it’s a smarter way to strengthen public safety communications and keep our communities safe.”
The upgraded VESTA Radio solution uses a Time Division Multiple Access (TDMA) over-the-air interface for voice traffic. The TDMA-based system will provide two voice traffic channels within a 12.5 kHz channel — doubling the talking capacity with the same channel bandwidth.
The upgraded system works in both FDMA and TDMA modes to support a mix of both Phase 1 and Phase 2 users on the system at the same time, providing interoperability and seamless migration of Phase 1 users to Phase 2 operation at the time and pace of the customer’s choosing.
The demonstration at APCO will feature Avtec, Inc.’s pure Radio over Internet Protocol (RoIP) with the VESTA Radio P25 Phase 2 system. Built on open standards, Avtec’s Scout™ dispatch console allows clients to use both legacy analog FDMA and TDMA radio technologies concurrently. Participants will first see how a legacy FDMA-based system that is only capable of making one call, shows the second call as busy. Then the TDMA-system will be switched into place making both calls possible, enhancing the capacity of the system and supporting more calls from first responders. (Source: Yahoo!/Marketwired)
12 Aug 15. Recent MDA SM-6 test demonstrates ship to shore tactical data link. Key Points:
• Results show no interoperability issues between USS John Paul Jones and BTS
• SM-6 SBT software modification will be integrated into new production missiles
The recent US Missile Defense Agency (MDA) and US Navy (USN) test of the Standard Missile (SM)-6, SM-2 Block IV, and Aegis Combat System also included an exercise examining the ability to transfer data from ship to shore.
USS John Paul Jones (DDG 53), the lone USN surface combatant taking part in the late July test, transmitted data including missile tracks to the Ballistic Missile Test Bed, San Diego (BTS).
The data transfer exercise is significant because it involves sending information over a tactical data link and exercises the MDA’s ballistic missile defense system (BMDS), Captain Tom Druggan, USN programme manager for the Aegis combat system, told IHS Jane’s on 10 August. (Source: IHS Jane’s)
13 Aug 15. DSTO conducts new joint Australia-US hypersonic fight test in Norway. The Australian Defence Science and Technology Organisation (DSTO) has successfully conducted a flight trial of the joint Australia-US hypersonic international flight research experimentation (HIFiRE) programme at the Andøya Rocket Range in Norway.
Dubbed as HIFiRE 7, the trial was designed to assess how scramjet engines start up at high altitudes, and also to measure how much thrust the engines produce at lower altitudes.
According to DSTO Aerospace Division chief Dr Ken Anderson, the experiment was intended to test complex systems necessary for the reorientation and control of hypersonic vehicles both outside and inside the atmosphere at hypersonic speeds.
The new development follows the completion of a suborbital flight and re-entering the atmosphere as the payload accelerated to more than seven times the speed of sound or 2km per second.
