The Benefits of Integrated Video Management

Building today’s advanced airborne Video Management Systems (VMS) involves the complex and frustrating task of integrating various components that have been sourced from a mix of vendors into a workable solution. A fully integrated VMS provides a better approach that maximizes operator usability and system flexibility while ensuring optimal interoperability. Curtiss-Wright specializes in tailoring exact VMS solutions to meet clients’ platform needs, and has delivered the most reliable and fully-featured VMSs in operation today, including those used by law enforcement agencies across the UK and Europe. Integrated VMSs not only reduce cost and allow for scalability, but also provide a level of flexibility and interoperability that would be unobtainable using components from multiple vendors.

Thinking Outside of the Box: Optimizing System Design With Embedded Expertise

Increasing technical requirements and tighter budgets provide challenges to integrators designing optimal system solutions for SWaP-constrained spaces. Dialoguing with highly knowledgeable COTS vendors early in the design process provides integrators with alternative systems engineering perspectives that result not only in better SWaP-optimized solutions, but reduced cost and schedule times. As a leading COTS vendor, Curtiss-Wright is exposed to a myriad of design problems every day, and has unmatched expertise in properly addressing constraints and providing innovative approaches to any design issue. Allowing our COTS hardware experts to mitigate SWaP-constraints early on in the embedded system design process results in highly-optimized re-architected solutions, and eliminates cost, weight, and schedule penalties.

Expanding GNSS Testing with Multiple Synchronized Signal Recorders

In order to greatly expand recording bandwidth, you can deploy multiple tightly synchronized recorders in the field. Averna studied the example of two RP-5300 recorders (2x50 MHz channels each) that were synchronously inter-connected to form a virtual recorder with total bandwidth of 200 MHz.

Eliminate Risk of Contention and Data Corruption in RS-485 Communications

The RS-485 communications standard was introduced in 1983 by the Electronic Industries Alliance (EIA) as a two-wire, half-duplex, multi-drop alternative to the point-to-point RS-232 interface. (Note: RS-485 can also be wired using 4-wires to enable full-duplex communication). RS-485 uses differential signaling to allow up to 32 devices to communicate peer-to-peer at distances up to 4000 feet. In most RS-485 configurations two signals, a positive and a negative, are run as a twisted pair. Since these signals are compared to one another rather than a ground reference like RS-232, RS-485 communication is less susceptible to external noise injected on the wiring and performs more reliably in industrial environments.

Performance Characteristics of Digital Frequency Discriminators

Digital frequency discriminators are key components of instantaneous frequency measurement (IFM) receiver systems as well as many other complex electronic warfare (EW) systems. However, to obtain optimum results it is essential to match DFD performance levels to a specific application. DFDs are integral components of IFM receiver systems; they may also be imbedded into a wide range of military systems such as radar warning receivers (RWRs), electronic countermeasures (ECM) systems, and electronic support measures (ESM) platforms, where they help provide instantaneous frequency measurement capability.
