At Goddard Space Flight Center (GSFC), Teltrium has experience in supporting all phases of the evolution of the Space Network (SN), expansions of the Near Earth Network (NEN), and Operations and Maintenance of the Satellite Laser Ranging (SLR) network. In the commercial sector, Teltrium has experience with the design and deployment of off-the-shelf broadband IP networks to support banking, intelligence, oil, and educational applications.
The Space Network (SN) is a data communication system comprised of a constellation of Tracking and Data Relay Satellites (TDRSs) and various ground terminals to connect to the space networks assets. Teltrium has experience in the acquisition of seven TDRS spacecraft and over twenty-five years of experience in ground segment evolution supporting and leading activities that encompass all aspects of NASA’s systems engineering life-cycle.
The Near Earth Network (NEN) provides telemetry, commanding, ground-based tracking, and data and communications services to a wide range of customers. The NEN provides these services to customers with satellites in low Earth orbit (LEO), geosynchronous orbit (GEO) highly elliptical orbit, Lunar orbit and missions with multiple frequency bands. For the NEN, Teltrium has experience in architecture studies and specification development for the NEN support of the Earth Observing System (EOS) missions.
Satellite Laser Ranging (SLR) network is a global set of interconnected stations that measure distances by bouncing very short pulses of laser light off special reflectors installed on satellites orbiting the earth and on the Moon which were left by the Apollo astronauts and Soviet rovers. These measurements are used by NASA to support national and international programs in Earth dynamics, ocean and ice surface altimetry, navigation and positioning.
Teltrium has experience with the Operations Center software enhancement/sustainment engineering including development, testing and implementation of software routines to automate legacy manual data operations; implementation of software transition to accommodate the new SLR Consolidated Laser Ranging Data (CRD) format conversion and data archival; and preparation of AS 9100 compliant software documentation for the Operations Center including the concept of operations, the system design document, and test plan and procedure.
Spectrum management engineering encompasses the technology areas related to planning coordinating, and managing and protecting the use of the electromagnetic spectrum. Teltrium has experience in spectrum technology research, data analytics, and the development of enterprise software infrastructure for the Defense Information Systems Agency (DISA) Defense Spectrum Organization (DSO), which enables information dominance through effective spectrum operations; provides direct operational support (such as electromagnetic battlespace planning, deconfliction, and joint spectrum interference resolution) to combatant commands; develops and implements net-centric enterprise spectrum management capabilities to enhance efficiency and effectiveness; pursues emerging spectrum technologies that may either benefit or impact DoD’s ability to access the electromagnetic spectrum; and advocates for current and future military spectrum requirements in national and international forums to protect DoD global operations.
Teltrium has led a number of spectrum technologies research activities at the DSO. Teltrium has identified, monitor and assesses emerging spectrum technologies (EST) that pose a benefit and/or threat to US access to the electromagnetic spectrum. Teltrium generated quarterly assessment reports quantifying the impact of new, identified spectrum technology. In addition, Teltrium performed detailed technical impact analyses of technologies identified as potential treads in the quarterly assessments reports. Teltrium has also let the development of and advanced modeling and simulation testbed which combined both RF simulation and network simulation to improve the impact of interference on victim receivers.
Teltrium experience in spectrum data analytics activities include the building of new databases compliant with Publication 8 standards, development of database synchronization technologies, and the automated analysis of data for compliance requirements. In the area of spectrum enterprise software development, we managed the development of DoD’s new spectrum management system which uses a Service Oriented Architecture (SOA) architecture and a web client to further automate DoD’s spectrum request and approval process.
