Gray Jay [UTIAS SFL]

Gray Jay is a formation flying microsatellite constellation of three satellites developed by SFL for the Department of National Defence�s science and technology organization, Defence Research and Development Canada (DRDC), to support Arctic surveillance technology demonstration under the All-Domain Situational Awareness (ADSA) program.

In August 2018, the Government of Canada awarded the project to SFL to develop the Gray Jay microsatellites. The based on the success of the CanX 4 and 5 formation flying demo in 2014, SFL offered to build a low-cost formation on SFL�s DEFIANT platform.

The SFL microsatellites developed for Gray Jay will include multiple sensors on a constellation of microsatellites operating in close formation in low Earth orbit to allow for quick and timely detection and identification of surface or airborne targets. These concurrently obtained sensor observations are expected to improve the responsiveness of detection and follow up, which may not be straightforward or timely when individual sensors are located on non-collaborating satellites.
