The worldwide focus on the concept of Space Situational Awareness (SSA) has come to the forefront in recent**years, encompassing everything from near Earth objects (NEO) such as asteroids to man-made orbital debris, to**the area of monitoring the security of valuable space assets. After being an active observer for some years,**Canada recently became a full member of the Inter-Agency Space Debris committee. Canada has also recently**signed, along with Australia, the U.K., and the USA, the Space Situational Awareness Accord. This will allow**for coordinated use of each partner's space capabilities for identifying and understanding objects in space. The**shared resources could provide continuous monitoring and authentication and validation via complementary**coverage especially for critical situations.**Honeywell has identified an opportunity to expand their company by integrating new detection technologies**into their cameras, and specifically using the APD arrays which Chapman's group at Dalhousie has expertise in.**Two emerging technologies have been a focus of the HONEYWELL AEROSPACE International Systems**division, but they do not have the capability to pursue a very promising third technology, APD arrays.**We propose to the Engage program to work with Honeywell Aerospace over the our joint pursuit of leading**technologies to address these issues, with our own value added applications in astronomy as an additional**motivator to this research.**To facilitate a detailed understanding of a leading technology for these applications (detector arrays of**Avalanche Photo-Diodes -- APDs), we will analyze and characterize these devices, providing the needed**parameters on the detectors to Honeywell Aerospace such that they can assess the viability of this technology.

近年来，全球对空间态势感知 (SSA) 概念的关注已经走到了最前沿，涵盖了从小行星等近地物体 (NEO) 到人造轨道碎片，到监控宝贵空间资产安全的领域。在担任了几年的积极观察员之后，**加拿大最近成为机构间空间碎片委员会的正式成员。加拿大最近还与澳大利亚、英国和美国签署了《太空态势感知协议》。这将允许**协调使用每个合作伙伴的太空能力来识别和理解太空中的物体。 **共享资源可以通过互补**覆盖范围提供持续监控、认证和验证，特别是在关键情况下。**霍尼韦尔已经确定了通过将新的检测技术**集成到其摄像机中来扩展公司的机会，特别是使用达尔豪西查普曼团队拥有专业知识的 APD 阵列。**两项新兴技术一直是霍尼韦尔航空航天国际系统**部门的重点，但它们并没有 有能力追求非常有前途的第三种技术，即 APD 阵列。**我们建议参与计划与霍尼韦尔航空航天公司合作，共同追求领先的**技术来解决这些问题，并以我们自己在天文学中的增值应用作为这项研究的额外**动力。**为了促进对这些应用的领先技术（**雪崩光电二极管 - APD 探测器阵列）的详细了解，我们将 分析和表征这些设备，向霍尼韦尔航空航天公司提供探测器所需的参数，以便他们评估该技术的可行性。
