远程制导地面攻击导弹(SLAM)是一种全球、全天候飞机投放的精确攻击型武器系统。主要工作方式为,载机上信息源生成目标位置和其它弹道参数在飞机投放导弹之前加载给导弹。导弹发射后,SLAM 的惯性导航系统(INS)控制导弹沿预定弹道飞行,飞行中用 GPS 修正导弹 INS,提供精确中段制导,通过 SLAM Maverick 导引头精确瞄准目标,提高捕获目标能力。导引头的图像信号通过武器数据链发送给控制飞机,操作人员观察图像,识别目标、选择指定目标的瞄准点。瞄准点控制器提供精确的攻击能力并使周围非军事区破坏减至最小。通向控制飞机的武器数据链是 Walleye 数据链。目前,SLAM 可以从A-6和 F/A-18 飞机发射和控制,也可由 A-7飞机控制。本文详细讨论 SLAM 使用的 GPS/INS 电子设备和软件的组合方法,以及设计中的一些综合考虑。独特的 SLAM GPS/INS 电子设备组成现役 HarPoon(捕鲸叉)导弹中段制导组件,包括捷联惯性敏感器组和数字处理器以及Rockwell-Collins 公司的单通道序贯 GPS 接收机处理器(GPS 第Ⅲ阶段用户设备改型)。除 GPS 接收机组件外,RPU(接收机处理设备)包含执行 SLAM 导航和卡尔曼滤波算法以及其他制导算法(包括导引头寻的导航处理器)。文中还报导了 SLAM 使用 GPS 辅助 INS 的飞行试验结果。
Long Range Guided Ground Assault Missile (SLAM) is a precision offensive weapon system launched by a global, all-weather aircraft. The main method of work is that the in-flight information source generates the target location and other ballistic parameters that are loaded on the missile before it is dropped by the aircraft. After the launch of the missile, SLAM’s inertial navigation system (INS) -controlled missiles fly along a predetermined trajectory. During the flight, GPS is used to correct the missiles INS to provide accurate mid-course guidance. The SLAM Maverick seeker precisely targets the target to improve the ability of the target to be captured. The seeker’s image signal is sent to the controlling aircraft via the weapon’s data link. The operator observes the image, identifies the target, and selects the target aiming point. The aiming point controller provides precise attack capabilities and minimizes damage to the surrounding demilitarized zone. The weapon data link to the controlling aircraft is the Walleye data link. Currently, SLAMs can be launched and controlled from A-6s and F / A-18s and from A-7s. This article discusses in detail the combination of GPS / INS electronics and software used by SLAM, as well as some considerations in designing. The unique SLAM GPS / INS electronics make up the active HarPoon missile mid-range guidance package, which includes strapdown inertial sensor sets and digital processors as well as Rockwell-Collins’ single-channel sequential GPS receiver processor (GPS Ⅲ phase user equipment modification). In addition to the GPS receiver components, the RPU (Receiver Processing Device) contains algorithms for performing SLAM navigation and Kalman filtering as well as other guidance algorithms (including seeker-directed navigation processors). The article also reports SLAM flight test results using GPS-assisted INS.
