RELEASE NOTES

2024-05-15 | Version 1.2

• • Add uncorrelated track (UCT) event support. UCT events are generated when a target is detected in an image collected by a node, but the detection does not correlate to any object in the catalog.
• • Add RIC volumetric searches, allowing users to task the network to search a volume of space around a target's predicted position. Volumes are specified in the Radial-Intrack-Crosstrack (RIC) frame of the target, and the search is executed by all nodes able to view the volume.
• • Add plane scans, allowing users to search an orbital plane. Plane scans are specified with a target ID, step size, & angular range to search. They can be used to track new launches, survey regions of GEO, or find lost satellites.
• • Survey instructions now support tasking a specific node to observe regions of the sky using topocentric azimuth and elevation angles.
• • Target correlation improvements: the target correlation algorithm has been improved to significantly reduce cross-tagging of targets and enable generation of observation sequence results (or UCT events) for all objects detected in images.
• • Observation sequence results now include solar phase angle for easier normalization & analysis of photometric data.
• • Additional network expansion: the OurSky network has expanded with improved coverage over the Indian Ocean & Asia-Pacific regions.

• • Add support for private targets. Previously, only targets in the general catalog were available for observation; now, private targets can be registered by TLE and tasked for observation. This target will only be visible to your organization.
• • Add support for J2000 time and place survey. Survey instructions are high priority tasks on the platform. Each step in the survey indicates a sidereal observation attempt at a given (Ra, Dec). When supplying coordinates, they should be given in J2000 reference frames using an SGP4 model for propagation.
• • Add support for LVLH search patterns. Search instructions are high priority tasks on the platform. Each step in the search indicates an observation attempt at a distance offset (along-track, cross-track, radial) in the local spacecraft frame. Offset values for each step should always be entered in absolute distance offset from the target's TLE, not relative to the previous step. Target rate and sidereal tracking are supported.
• • Our network has expanded with additional nodes globally - with large improvements in Oceania and other southern hemisphere locations. View the effect of these expansions by querying upcoming potential observation windows via our satellite-target-potentials API. This API determines when and where a target will be visible by a node in our network.
• • Add support for monitoring failed observations. You can get the status of observations tasked on the platform for an organization, for a target, for a search instruction, or for a survey instruction.
• • Observation sequence results now hold a list of features that contain target correlations. Target correlations are ordered from most likely to least likely, and are based on comparing predicted to actual streak angle, distance, and length.
• • Observation sequence results now hold a bounding box around the extracted target, making it easier for customers to integrate their observation results into their internal platforms.
• • OurSky has completed Global Data Marketplace (GDM) integration and is now able to respond to customer solicitations via GDM.
• • Additional webhook events for search finished, survey finished, observation finished have been added to the platform so customers can get real time tasking results.
