Ensuring optimal use of a satellite's allocated spectrum and power resources is critical to the success of satellite operators. Increased utilization directly translates to increased revenue.
SED is providing spectrum and power optimization solutions that simplify resource planning and real-time management.
SED provides satellite resource optimization solutions on two levels:
- Real-time resource management, and
- Spectrum planning.
Our real-time management solutions allow spectrum to be assigned on demand, applying your spectrum to where your customers need it and minimizing underutilized spectrum allocations. These systems assess requests for spectrum against all of the current constraints and make assignments in real-time. The process of assigning spectrum to carriers can become totally automated and greatly reduces the demands on frequency planners for accurate predictions. Real time resource management is ideal for handling the unpredictability of where user hot spots can occur.
Our spectrum planning tools assist the operator at the planning stages whereby all of the constraints can be identified. These constraints are then checked and utilized when planning the allocation of spectrum and power to carriers, to ensure that as many carriers as possible can be accommodated in a minimum of spectrum. Planning constraints such as spectrum allocation, orbital model, satellite payload characteristics and types of carriers for a given constellation of satellites, to name a few, are all taken into consideration during the planning process.
Intermodulation and interference calculations are performed across all of the carriers in a plan. Interfering carriers can be identified and eliminated at the planning stage, before they become a real-time problem that affects the quality of service. With the visualization tools that we provide, a user can see the free spectrum where new carriers can be added and see the effects of a new carrier on all of the other carriers.

This is what Inmarsat has to say about SED's Satellite Resource Management systems:
"SED provided a complete turnkey solution, installing a fully-operational system on time and on budget that met or exceeded all our requirements. Today the system continues to provide the reliable service we demand to keep our customers satisfied. As our network expands and new services are added, we keep going back to SED for management system solutions. We are confident that SED will continue to provide the performance we need."
