Velocity® is an IP-based satellite communications system specifically designed for HTS operators deploying managed services who require massive scale, API integration and advanced mobility.

HTS operators are able to quickly address market requirements for fixed and mobile applications with maximum flexibility and lowest risk.

Today, Velocity is the de facto standard for leading satellite operators – including Inmarsat, Intelsat, SES and Telenor – serving over 400 beams of HTS coverage worldwide.

  • Overview

    Velocity® consists of operating software and leverages the universal hub and line card portfolio and remote portfolio for maximum investment protection. Velocity® builds on the capabilities of Evolution® for greatly expanded scale and is specifically designed for satellite operators to deploy managed HTS architectures. It consists of three main differentiators; an ability to manage a single bandwidth pool across multi-spot beam capacity globally, mobility capabilities in a multi spot-beam environment and the support for carrier-grade reliability and resiliency.

  • Features

    Flexible, Efficient Core Architecture

    ST Engineering iDirect hub can connect to any frequency band on all satellite architectures. Velocity is built on DVB-S2 with ACM with Adaptive TDMA and multiple efficiency technologies to allocate bandwidth efficiently over distributed networks, while automatically adjusting to dynamic traffic demands and changing network conditions. The modular hub and line card system enables operators to operate across all business models, including VNO and managed service models and easily add new capabilities with over-the-air software upgrades.

    Global Bandwidth Management

    Global Bandwidth Management enables operators to manage a single bandwidth pool to ensure a customer’s complex SLAs across a large coverage area spanning multiple spot beams. This includes a Group Quality of Service (GQoS) system, load balancing, scheduling, geoscope and a Fair Access Policy Scheme (FAP). It provides Satellite Operators with the option of logically partitioning the satellite capacity spanning several beams for Virtual Network Operators (VNOs) through the creation of Group Service Plans.

    Advanced Mobility

    Advanced mobility features enable fast-moving remotes to automatically cross multiple spot beams within a short period of time, maintaining a constant IP session. These capabilities include: Automatic Beam Selection (ABS) technology features beam switching with no manual intervention across multiple satellite footprints to enable global connectivity. Another feature, called Spread Spectrum waveform, supports very small antennas on aircraft, maritime and land- based vehicles. Multicast Overlay enables an operator to offer broadcast and unicast services simultaneously in the most efficient manner. Other high-speed Communications on the Move (COTM) features include Doppler compensation, fast reacquisition after blockage and fast beam-switching.

    Carrier Class Service Reliability

    Supports full redundancy and rain diversity of the network infrastructure, as well as sophisticated QoS to ensure SLAs under any weather condition by incorporating adaptive waveforms.

    Integration with Terrestrial Networks

    Velocity mirrors the quality and reliability of terrestrial services, ensuring an enterprise-class user experience, and can operate seamlessly as part of an integrated global IP network. Layer 2 over Satellite (L2oS) provides protocol transparency through a Layer 2 architecture that offers seamless integration into an end-to-end network.

  • Velocity 2.0 Overview

    Velocity 2.0 is the go-to software release for all partners and features new capabilities as well as operational improvements. The Velocity platform is ideal for advanced mobility networks and large-scale deployments. This release supports the following remotes: iQ Series (iQ DT, iQ 200, iQ LTE), 9 Series (9350, 900, 950mp), and X Series (X7, CX700, CX780).

    Note: Before upgrading from Velocity 1.6.1.x to 2.0.0, the NMS must be upgraded to Pulse 2.6.

    Key Features

    • Multicast Overlay for the CX780
    • Layer 2 over Satellite (L2oS) on iQ Series
    • Remote Commissioning for iQ DT/200 with Integrasys Satmotion
    • Fair Access Policy (FAP) enhancements
    • Support for iQ LTE series
    • Faster DVB-S2 Beam Selection
    • Beam Load Management improvements
