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.

全球关注的是太空情境意识（SSA）（SSA）最近的**数年，涵盖了从近地球物体（NEO）（例如小行星）到人造轨道碎片的所有事物，到**监视有价值的太空资源安全性的领域。在成为活跃的观察者几年后，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情境意识协议。这将允许**协调每个合作伙伴的空间功能，以识别和理解太空中的对象。 **共享的资源可以通过补充**尤其是在关键情况下提供持续的监控，身份验证和验证。有能力追求非常有前途的第三种技术，APD阵列。分析和表征这些设备，为霍尼韦尔航空航天的检测器上提供所需的**参数，从而可以评估该技术的可行性。
