Satellite Ground Segment Solutions and Capabilities of SDT

Tarih: Issue 88 - January 2019

Airborne and space-based surveillance and reconnaissance are essential for successful military missions. Such capabilities are critical for troop protection, situational awareness, mission planning, damage assessment, and others.

Space based platforms provide capability of periodic surveillance for large areas without any geographical limitations with different kinds of information.

SDT started its activities regarding the Satellite Ground Segment, with GOKTURK-1 military surveillance project. SDT is responsible to develop User Services Subsystem of the GOKTURK Ground Segment in scope of the GOKTURK-1 Program as a sub-contractor of the Aselsan since 2010. SDT has also been involved in the GOKTURK-3 (SAR Satellite) Program which started at the end of 2013, as a sub-contractor of Aselsan. Consequently; SDT is responsible to develop User Services Subsystem of the GOKTURK Ground Station under Turkish Air Force command. GOKTURK Ground Station will serve all of the GOKTURK satellites (GOKTURK-1, GOKTURK-2 and GOKTURK-3). On 5th Dec,2016; GTK-1 was launched and SDT Software solutions have been used in real life applications with high success and availability.

SDT is improving  her capabilities regarding Ground Stations in order to also support also Airborne platforms after the experience on the GOKTURK-1 Project. With this target; SDT has started to develop multi-mission ground segment solutions for both space and aerial platforms. SDT has been designing and developing SDT Enterprise Service Infrastructure (SenseI) as a core service framework technology. Receiving data from producers/sources of satellite/UAV payloads are processed with ingestion steps which are aligned with OGC and INSPIRE  metadata standards. Moreover, image process adaptors are managed with ESA Generic IPF. Sensei is a middleware SDT solution, applicable in horizontal and vertical scalesable, and also, “Open Archival Information System (OAIS)” is used for archiving processes. Sensei consists of pluggable workflows, business logic modules, and data process ing and data package elements. Sensei communicates with man machine interface (MMI), catalogue, archive and dissemination, and image exploitation services under single sign on, authentication and authorization policies.

SDT developed a modular, end-to-end, comprehensive solution for Intelligence, Surveillance and Reconnaissance (ISR) requirements, from imagery and video acquisition to Geospatial Intelligence (GEOINT) dissemination. Within this scope; SDT has provided complete solution proposals to different countries according to their intelligence needs.

Unmanned Aerial Vehicles (UAVs) gather huge amounts of video data, but it is extremely labor-intensive for operators to analyze the received data, as it can lasting many hours. Data collected from UAVs must be reviewed quickly to support real-time operations in the field, whereas it also needs to be analyzed in more depth and over longer time frames to support mission planning and intelligence gathering.

SDT has also has intensive experience regarding image formation; processing and exploitation capabilities have been gained by different projects. With these capabilities and experiences ; SDT can integrate data and image processing tools in order to process data provided by Electro-Optical (E/O), Infra-Red (IR) and Synthetic Aperture Radar (SAR) sensors located on satellite, airborne or land platforms

SDT has capability and products for:

Service request and task management

Image and video ingestion 

Archive, manage and serve image and live video stream

Real-time and/or offline image analysis and exploitation (The result of the offline image processing would enable the detection of more complex targets compared to that of real-time image processing)

Ability to create annotations on streaming video

Fusing image and video with other intelligence data from other sources

SDT can provide end to end custom image processing and exploitation solutions tailored to the intelligence and command & control requirements of the user.

All these capabilities can be integrated in a system application and offered as a project that can be tailored to specific needs.
