High Throughput Satellites: A Bright Future For MILSATCOM

From MilsatMagazine

By Karl Fuchs, Vice President of Technology, iDirect Government Technologies (iGT)

The military has a voracious appetite for communications. However, shrinking Department of Defense (DoD) budgets threaten to quash the military’s development and use of next-generation communications to support the warfighter.

This doesn’t have to be the case.

Technology can help to solve the biggest challenges of using satellite communications: Bandwidth and cost. New High Throughput Satellite (HTS) technology can help advance MILSATCOM while offering DoD users the high quality, consistent reliability and lower costs they need.

Take, for instance, the military’s widespread use of intelligence, surveillance and reconnaissance (ISR) missions and other full-motion, high-definition (HD) video feeds. These are the fastest-growing, bandwidth-consuming applications used by the warfighter.

One of the first, real-world applications of ISR missions was the cleanup effort for the Gulf Oil Spill. iGT and the industry were able to achieve return channel bandwidths to support HD video feeds. However, the military end-user missions demand more in the way of deliverables. The achievable data rates at the time of the spill were limited by the aperture of the antenna as well as the G/T and EIRP of the hemispherical beam of the satellite. Read More

ITC Global Will Upgrade Global Mining-Sector Satellite Network To Deliver Higher Throughput Rates Over iDirect Platform

Service provider to leverage iDirect’s X7 remote and Evolution iDX 3.2 software to achieve 20+ Mbps data rate for high-bandwidth IP applications

Herndon, Va., February 3, 2013 – VT iDirect, Inc. (iDirect), a company of VT Systems, Inc. (VT Systems), today announced that ITC Global will upgrade its mining-sector satellite network to iDirect’s soon-to-be-released iDX 3.2 software featuring Adaptive TDMA, and will deploy the next-generation Evolution X7 remote. ITC Global is a leading provider of global, enterprise-class satellite communications to premier mining companies around the world, and will be the first service provider to offer iDX 3.2 and X7 capabilities to the mining sector. iDirect is a world leader in satellite-based IP communications technology.

The upgrade advances ITC Global’s commitment to continual network innovation and will allow ITC Global to satisfy the 20+ Mbps bandwidth requirement the mining sector now demands. Faster data throughput will improve the network’s ability to handle multiple IP applications on a unified platform, such as Voice over IP, radio over IP, CCTV, remote permission and control, and the automation of critical operational tasks. These communications services enable mining companies to increase business productivity; ensure compliance with Health, Safety and Environmental initiatives and commitments; achieve the timely delivery of projects; and shorten overall time to market while maximizing continuity of supply to end customers.

High-Throughput Satellite Remote Introduced By iDirect

From The Digital Ship

Key performance statistics for the Evolution X7 remote, the first in a family of next-generation remotes that have been optimised for Adaptive TDMA throughput performance and operate with high throughput satellites, have been released by iDirect.

Built on a new multi-core hardware system, iDirect says that the X7 can reach up to 100 Mbps of combined inbound and outbound throughput, with more than 20 Mbps on the return channel.

The Evolution X7 uses dual DVB-S2 demodulators with fully independent RF chains, supporting voice and data services while simultaneously receiving up to 12 shared, high-definition multicast channels over the same or a second transponder or satellite.

The X7 also features an embedded 8-port switch for physically segregating multiple end user traffic groups based on VLAN tags. The new remote also comes with multiple embedded PSU configurations to power higher wattage BUCs. Continue>

iDirect TAC Tips – How to change HLC failover timer

How do I change HLC failover timer?

On NMS running iDS 6.0 or newer iDirect software, line card failure detection time can be configured by changing the value of EVT_DIAG_TIMEOUT.  Default value = 6 seconds.  Default value might not be adequate for very large networks or to handle momentary Ethernet glitches and false failover detection may happen. In such cases, you may want to increase the default value using below procedure.

1- Edit the file /home/nms/utils/nms_start on the NMS

2- Search for line:

evtsvr

3- Just below above line add the following line.

export EVT_DIAG_TIMEOUT = <new_timeout_in_seconds>

4- Save the above file and restart evtsvr process. Read More
