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，全世界对空间态势感知概念的关注已达到最前沿，涵盖从小行星等近地物体到人造轨道碎片，再到监测宝贵空间资产安全的领域。加拿大在作为积极观察员若干年后，** 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、和美国的空间态势感知雅阁。这将使 ** 能够协调使用每个伙伴的空间能力，以查明和了解空间物体。** 共享资源可以通过补充 ** 覆盖范围提供持续的监控、认证和验证，特别是在关键情况下。霍尼韦尔已经发现了一个机会，通过将新的检测技术 ** 集成到他们的相机中，特别是使用达尔豪西的查普曼小组拥有专业知识的APD阵列，来扩大他们的公司。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，但他们没有能力追求非常有前途的第三项技术，APD阵列。我们建议Engage计划与霍尼韦尔航空航天合作，共同追求领先的技术来解决这些问题，并将我们自己在天文学方面的增值应用作为这项研究的额外动力。为了便于详细了解这些应用的领先技术（雪崩光电二极管的探测器阵列-APD），我们将分析和表征这些器件，向霍尼韦尔航空航天提供探测器所需的参数，以便他们可以评估这项技术的可行性。
