he said, ‘Yeah, I know.’ So I said, ‘OK, we can do that. Anything’s possible.’” Going forward, Hardy said, Ampex Data Systems’ continued success will hinge on whether it is able to effectively keep its ear low to the ground for changing requirements and customer demands. Because the funding for US government programs is currently very limited, some organizations are approaching Ampex for a data recorder product having already settled on or configured a specific recording platform or format. This past November, Ampex announced that it had signed an agreement with Boeing to incorporate the latter’s IntelliBus data acquisition technology into the Ampex data recorder product line, fi rst as a Network Interface Control (NIC) module on its miniR700 solid-state recorder (Ampex’s bestselling product, with 14 to be adapted to various input devices very quickly. In its 10-plus years of making data recorders, VMETRO has grown to rely heavily on COTS products, said Tom Bohman, vice president of business development. “I’d say 90 percent of our products are COTS, and it’s really a matter of targeting a product with an appropriate input and driver and a relatively small amount of NRE [non-recurring engineering] to connect it to the recording engine,” Bohman said. “I think this really makes us stand out in terms of the flexibility and costeffectiveness that we bring to what otherwise might be considered a custom recorder.” Curtiss-Wright’s Vortex Ultra Wideband (UWB) data recorder, designed for SIGINT and radar applications, offers 1-GHz analog bandwidth, with dual-channel 8-bit 1-GHz ADC and 2 Gigasamples/ second recording speed. The Vortex Ultra Wideband Recorder, a product of Curtiss-Wright Controls Embedded Computing, is a dual-channel, 8-bit analog input recording system. 448 Gigabytes of removable memory). More and more customers want data recorder units that meet certain format conditions, or what Hardy calls standard-compliant systems, which explains why Ampex currently is undergoing an IRIG 106 Chapter 10 compliance process. (Type 1, NSA-certified data encryption capability also is a popular customer request, according to Micha at L-3 Communications, and in development at the company.) It is a lesson other data recorder manufacturers have learned along the way as well – the former data recorder manufacturer VMETRO, now under the umbrella of Curtiss-Wright Controls Embedded Computing, believes that its biggest asset to the EW and SIGINT community is its open data recording systems that can FINDING STORAGE SPACE Perhaps one of the most consistently underestimated problems by end users of data recorders is data archival. For EW and SIGINT missions that call on a warfighter to record data multiple times a day for a month or longer, organizing and figuring out a way to access such large amounts of data can be a problem. Although data archival is a fairly sophisticated challenge, data recorder manufacturers are doing their part to offer solutions and work toward engineering better technology. CurtissWright Controls Embedded Computing manufactures a rugged, six-disk JBOD (Just a Bunch of Disks) storage system called SANbric™ for short-term data storage for SIGINT, ELINT and COMINT missions, and data is later drained from this unit using processor-based software for long-term storage on low-cost RAID technology. DRS Technologies produces the RDA-100 Signal Library System, part of its RDA product line for SIGINT signal library, training and system validation applications, which transfers files to disk at 430 Megabytes/ second, network at 100 Megabytes/second or linear tape open (LTO)-3 tape at 60 Megabytes/second. L-3 Communications is stretching its neck even further into the data storage business by developing embedded storage solutions for UAVs. For an aircraft such as the United States’ Predator UAV, for example, removable memory is not nearly as essential as it is for manned aircraft because the data that a UAV captures is automatically datalinked during its fl ight; however, this datalinking process has its problems. As Micha explained, “Often, the sensor data rate that a [UAV’s] sensors are collecting at is much faster than the datalink can send down to the ground, so there needs to be a kind of buffering system between the sensor and the datalink. What we’ve started to do with a couple of customers is, instead of a removable recorder, we’ll put an embedded storage system onboard – a card or a couple of circuit cards – that actually acts as a big buffer. All the data comes into the aircraft very quickly from the sensor, and it goes into our storage system and we buffer it and then send it out of our storage system to the datalink at the rate that the datalink can output it.” Dan Simard, vice president of business development at EONIC B.V., a Netherlands-based company that specializes in high-performance wideband recorders, said his customers rely on LTO magnetic tape to offload data for archival, but suggested that this 10-year-old technology has its limitations in terms of speed and capacity. “I expect a lot of advances in the archive market down the road, and we can see some of these with LTO-5 imminent and LTO-6 on the roadmap,” he said.
