Mercury offers integrated UAV-based reconnaissance system
The VistaNav-SSR integrated unmanned aircraft system from Mercury Computer Systems in Chelmsford, Mass., is composed of a ground station, integrated VistaNav synthetic vision system, a small unmanned aerial vehicle (UAV), and various electronic sensor systems. Designed to improve operational mission capabilities for airborne intelligence applications such as oil and gas pipeline monitoring and forest fire detection, VistaNav-SSR (Smart Surveillance & Reconnaissance) is extending the benefits of 3-D situational awareness to small unmanned aircraft systems. The VistaNav-SSR system enables customers to perform missions while minimizing human error and human fatalities in hazardous applications. The capabilities of small, low-power unmanned aerial systems are growing in popularity for a broad mix of airborne surveillance applications. VistaNav-SSR includes Mercury’s ACIP technology that allows plug-and-play integration of payload sensors, avionics, and data-link subsystems into small, light, and low-power UAVs. Because of integration and miniaturization, ACIP enables integration of functions such as video stabilization, compression, metadata generation, collision avoidance, and flight management, as well as anomaly detection, in a flexible configuration package. The VistaNav-SSR is based on the Vector-LRE airframe from IntelliTech Microsystems Inc. in Bowie, Md. As a tactical-class UAV, the Vector-LRE provides a payload-to-weight ratio that allows the integration of multiple payload, navigation, collision-avoidance, and communication subsystems onboard.

Power-amplifier module from Merrimac Industries drives UAV communications links
Communications and networking between unmanned ground vehicles (UGVs) and unmanned aerial vehicles (UAVs) and control bases require a broadband transmitter capable of supporting secure, error-free video and data links. In support of these ruggedized transmitters, Merrimac Industries Inc. in West Caldwell, N.J. is offering a customizable power-amplifier module (PAM) based on the company’s Multi-Mix multilayer circuit technology. In contrast to traveling-wave-tube (TWT) power modules, the Multi-Mix PAM offers superior MTTF performance and the capability of maintaining reliable communications in high-vibration UAV/UGV environments, company officials say. The Multi-Mix PAM can be specified for operating bandwidths in excess of 40 GHz for wideband links and at power-output levels in excess of 100 watts. For small footprints, the customizable module is based on several circuit layers joined by a fusion-bonding process. In this manner, the circuit layers are joined with weld-like strength; the circuitry is in turn bonded to a bottom metal layer for effective heat dissipation. Because these circuit layers exhibit good thermal conductivity, modules can be fabricated with embedded transistor die, rather than packaged devices, for compact UAV and UGV transmit amplifiers. The Multi-Mix PAM can be built with a customer’s preferred high-power device technology, including gallium arsenide (GaAs), gallium nitride (GaN), and silicon carbide (SiC) transistors. For higher levels of integration, the Multi-Mix PAM technology also supports additional building-block functions, such as filters, mixers, and power combiners, on the same substrates as the amplifier circuitry.

L-3 Link offers Predator UAV Mission Aircrew Training System
L-3 Link Simulation & Training in Arlington, Texas, is offering the Predator Mission Aircrew Training System (PMATS), which consists of a form, fit, and function user interface for the pilot and sensor operator stations that uses ground-control-station hardware from General Atomics. Link has integrated this hardware with training-system software to develop a high-fidelity training system. PMATS models all Predator MQ-1 systems, sensors, and weapons (in the future PMATS will support training on the MQ-9 Predator B aircraft). Environmental simulations support both initial qualification and mission training, including emergency and abnormal-procedures training. PMATS is integrated with instructional systems including an Instructor Operator Station, which supports brief and debrief capabilities. To support collective training exercises, multiple PMATS units can be linked over both local and long-haul networks for Distributed Mission Operations (DMO). For students training within a PMATS, the level of realism between simulated exercises and real-world operations is transparent. Use of Predator OEM-production pilot and sensor operator-station hardware helps ensure training exercises have a realistic look and feel. Further enhancing realism, Link has developed a PMATS training environment that accurately simulates real-world conditions that Predator aircrews experience. This training environment, which operates within a high-fidelity database, simulates challenging conditions including variations in thermals, slope winds, wind shear, visibility, icing, and runway conditions.
