will be able to record their location and transmit it constantly over the air. Such signals can be picked up and used to chart the host vehicle's location on, for example, a battlefield management system (all the combat radios are vehicle mounted). The information will be up-to-the minute, giving a commander almost real-time information. This is something, Whichelo says, the combat arms have long wanted. The CNRE will also be ca- pable of transmitting text messages, although Whichelo character- izes the data stream as "quite thin" – it will only be capable of very brief messages. General Dynamics will begin providing the army with the enhanced radios in May 2015, with the final delivery slated for 2017. GDC will be installing new hardware and firmware (es- sentially propriety company-created software that runs on small embedded processors in the circuit cards), notably a new commu- nications security board to replace one originally manufactured by the company. This will give the sets enhanced cryptographic pro- tection. Rockwell Collins is writing some of the firmware, and Corn- wall's SigmaPoint is building cir- cuit boards for use in the enhanced radios. Craig Jansen, GDC's vice-presi- dent of Land and Joint Solutions, calls the CNRE a "software-de- fined radio." To see it being used in a vehicle with a keyboard and monitor, it looks as much like a PC as anything. At present, says Whichelo, the monitor "provides you with menus that allow you to choose frequencies. You can flick between them fairly regularly." It can also be used as a diagnostic tool to "investigate any faults you might have with the radio." Within a few years, however, "we have a battlefield management system that is going to be introduced," he said. Designed to be displayed on the terminals using the "blue position awareness" data transmitted by the radios, this should give those in the field a much better idea of their place in the battle space. Jansen said the upgrade gives the army enhanced radio perfor- mance at "something like 20 percent of going out and acquiring a new software-defined radio. It is a great example of how to extend the life of an in-service platform." c c4iSr www.vanguardcanada.com DECEMBER 2014/JANUARY 2015 33 ian coutts is a freelance writer, author of four books, and a frequent contributor to Vanguard. "Everything old is new again," is how the song puts it. It's not an approach typically associated with military procurement. That's more a case of everything new is new, period. And much more expensive than what was there before. But the idea behind that song – or something very like it – seems to have been the guiding spirit behind the Department of National Defence's October 25 announcement of a $122 million contract for General Dynamics Canada to upgrade the Canadian Armed Forces' existing fleet of Combat Net Radios. Partnering with Rockwell Collins Canada and their own subsidiary, Sigma- Point, General Dynamics will be upgrading the more than 11,000 radios that it originally supplied the forces back in the early '90s, extending their usefulness by another ten years. Lieutenant-Colonel Fred Whichelo, with the Canadian Army's Directorate of Land Requirements, says the upgrades will improve the performance of the radios in two key areas: cryptography and data compatibility. The key algorithms that protect information sent over the ra- dios were nearing the end of their effective lives, he explained. "We need to make sure we stay in step with the cryptographic modernization of our key allies" in order to maintain interoper- ability on operations. "We also wanted to take advantage of technology to expand what was effectively just a voice radio into something that had some data compatibility as well," he said. "The most important thing that is going to give us is...'blue positional' awareness." The Enhanced Combat Net Radios (or CNRE's as their known) will mean better positional awareness Army combat radio upgrade "The most important thing [it] is going to give us is...blue positional awareness."
