2014年9月似乎是很久以前的事了. 这就是S&K国际大厦, 有限责任公司 (ITL) and their technology partner Elbit Fort Worth (EFW) received the initial contract award notification on U.S. Customs and Border Protection’s (CBP) marquee border security program, 综合固定塔(IFT)计划. 通过IFT项目, 海关和边境保护局部署了一个非开发性的, 证明, 低风险的, and reliable baseline integrated sensor surveillance 系统.

The IFT 系统s consists of a combination of some of the most advanced technology available today. IFT传感器塔由一个远程, 360-degree radar that is paired with a long-range Electro-Optical (day) and Infrared (night) camera payload, 激光测距仪, 红外(IR)照明器. This technology suite is installed atop a lattice tower. The 系统 runs on a renewable solar battery powered 系统 that has a propane generator back-up. Each IFT sensor tower unit resides within a secured, fenced-in compound. The 系统 detects an average-sized single walking person who is obscured up to 90% for periods of up to 3 seconds at a range of 7.5英里. The sensor feeds from each IFT tower is back-hauled to a centralized Command and Control Center where U.S. 边境巡逻人员利用这个系统来探测, 识别, and classify Items of Interest like drug smugglers and illegal border crossers along the U.S. -亚利桑那州南部的墨西哥边境.

根据2014年授予的初始合同, ITL负责设计, 制造, and installation of the eight sensor and communication towers located in the Nogales Area of Responsibility (AoR). ITL has total site Architectural and 工程 responsibility for the foundations, 塔结构, 电力系统, Federal Aviation Administration (FAA) 019e compliant grounding 系统, 安防系统安装, 传感器安装. ITL制定并执行所有物流解决方案, which contributed to the completion of the project 提前完成计划. 国际机场完成铁塔建设, 传感器组件, 测试和集成, and installation of the 电力系统s and sub系统s under budget, 提前完成计划, 而且没有更改命令. The total time to complete the Nogales AoR was less than 4.从开始到结束5个月，一个真正惊人的壮举.

自最初部署以来, in similar fashion and performing the same scope mentioned above, ITL has completed the deployment of IFT sensor and communications towers in the Douglas, 的索诺伊塔, Block-1(前身为SBInet) AoRs取得了巨大成功. ITL is in the final stage of the original contract and is currently deploying IFT sensor and communications towers in the last IFT AoR which is Casa Grande. This is a unique and fitting location to complete the initial contract, because the Casa Grande AoR resides within the Tohono O’odham Nation, a federally recognized tribe occupying tribal lands in Southwestern Arizona. ITL也是一个部落所有的实体, giving the company a unique appreciation for Tohono O’odham Nation Tribal leadership concerns about the number of permanent IFT towers planned for installation and the environmental impact of these installations on tribal lands.

To address these concerns, ITL designed a special cell-block foundation solution. The cell-block technology combines the benefits of nonpermanent relocatable equipment with the rigidity and support provided from a conventional fixed 3-legged lattice tower. This unique design allows CBP to comply with land-rights and environmental restrictions associated with these tower sites while still providing the tower rigidity specifications that the IFT Program relies on for optimal 系统 performance without the need to perform tower tensioning, 系统, 传感器和天线调整, or other costly recurring relocatable tower maintenance activities.

IFT项目对ITL的总价值超过4000万美元. When the Casa Grande AoR is complete later this calendar year, ITL will have successfully completed the deployment of 66 sensor and communications towers spread across six U.S. 边境巡逻队. ITL is poised for success on future iterations of the program that may entail a combination of CBP’s IFT and Remote Video Surveillance System (RVSS) which when re-competed in March of 2021 will deploy IFT and RVSS towers in California and Texas.

So, while 2014年9月似乎是很久以前的事了, March 2021 is right around the corner.
