Optimize satellite capacity and maximize service delivery

Calian’s next-generation satellite capacity management system (SCMS) delivers the latest advances in satellite communication payload and link propagation analysis techniques and modelling. The SCMS is an advanced software system used by satellite operators and satellite service providers for planning and managing the use of their satellite capacity.

The SCMS models the complexity of today’s high-throughput satellite payloads including the detailed analysis of payload paths, filter responses, and transponder back-off and intermodulation noise impacts. 

The SCMS is ideal for Ku- and Ka-band systems, supporting site diversity analysis, the latest ITU-R weather models and a sophisticated analysis of beam coverage, including interference between beams reusing frequency.

Global resource manager

Our global resource manager (GRM) is a real-time software system that dynamically manages the resources of a digital communications payload. Interfacing with the network and satellite ground control systems, the GRM selects, prioritizes and establishes communication channels on the satellite in response to traffic demand.

Enhanced global resource manager

Our enhanced global resource manager (eGRM) manages the payload resources of high-throughput satellites. Supporting global coverage, including fixed and mobile terminal services, it was originally introduced to support the roll-out of Inmarsat’s Ka-band Global Xpress service, the world’s first global HTS network of satellites.

Satellite load manager

Our satellite load manager (SLM) adds automated short-term resource management capabilities to global VSAT operations. It augments an existing VSAT platform to reduce, eliminate or prevent network congestion, helping to ensure terminals are operating within regional regulatory constraints, and ensuring terminals are assigned to satellites with unobstructed views and favourable skew angles.

Calian’s EarthMesh platform empowers space agencies, satellite operators and terrestrial operators to model, analyze and optimize the use of communication links in multi-orbit, multi-constellation environments. This scalable platform is designed to address the complexities of the burgeoning growth of satellites in space.

EarthMesh is an elastic computational engine that models and analyzes extensive and dynamic networks of space- and ground-based assets over time and space. It empowers space agencies and satellite operators to plan and manage their missions and operations efficiently, optimizing RF and optical communications.

Interference management and mitigation

Calian offers state-of-the-art interference management solutions, designed to maximize spectrum usage by providing a comprehensive and intelligent approach to interference management. This solution goes beyond traditional interference monitoring, incorporating advanced modelling techniques to optimize frequency reuse, beam layouts and signal quality. 

Satcom planning and analysis

Calian has a suite of planning tools and applications designed to help operators manage their satellite networks. These include applications for long-term capacity planning, sizing service based on customer requirements and beam coverage analysis.

The capacity sizing tool (CST) helps satellite capacity planning and sales teams design and sell service plans based on aligning QoS needs with satellite performance characteristics across geographic regions. The CST determines achieved availability, data rate and a nominal MODCOD for a service plan across the operating geography by considering the satellite performance characteristics and propagation models for link impairments for six different operating scenarios.

The capacity planning tool (CPT) tracks the available and used capacity of a satellite fleet. Designed to scale from one satellite to a global fleet, the system tracks—over time—payload configurations (channels/beams), potential and committed service for individual and group services, and network usage statistics. Services are represented by data rates, symbol rates, geoscopes and time frames, and are augmented by demand and congestion statistics obtained from the ground segment.

Calian’s antenna coverage tool projects satellite antenna patterns onto 2D and 3D world maps to enable users to predict, visualize and analyze beam coverage. The tool leverages sophisticated algorithms to model the radio wave propagation and the impact of geographical features, such as buildings and terrain, on signal strength and quality. Engineers use this information to optimize antenna placements, orientations and settings to maximize coverage and minimize interference. Supports Satsoft.
