Whether for enterprise, commercial, government or maritime services, customers who operate in remote and harsh environments use satellite services for time-sensitive, mission critical communications. Whether communicating back to headquarter offices or providing morale services to staff and crew members, it is vital that these customers that operate in remote and harsh landscapes have access to high availability, reliable communications links.
High throughput satellite (HTS) technologies with unprecedented bandwidth and power resources are being viewed as “the wave of the future” for satellite communications and networking services. Despite this tremendous potential, there is a great deal of misperception and lack of understanding about these new technologies among both customers and the industry at large. With different options, how do you pick the best one for your company’s needs? Continue>
Onboard satellite communications are evolving as maritime operators are finding more critical applications for broadband at sea, beyond basic voice and data connectivity. A new trend is the need for higher throughput networks to run multiple bandwidth-heavy applications onboard all vessels. And as High Throughput Satellites (HTS) come online, this trend is projected to grow.
To support these applications, iDirect is rolling out iDX 3.2 and the X7 remote.
X7 – The remote that can run a huge wave of applications
The X7 remote provides a significant increase in performance and is optimized for high-performing networks. As future iDirect software gets released, the X7 will be able to increase combined network throughput up to 100 Mbps.
This remote will play a major role in supporting a multitude of applications across the maritime market. Let’s examine three segments: Cruise ships, offshore oil and gas, and shipping.
Cruise ships: Cruise lines are connecting a floating community on board their vessels by supporting passengers with voice, data, video and Internet applications. Passengers can use these broadband applications for voice and onboard GSM, interactive guest services, entertainment and video streaming, and Internet on mobile devices. Read More
VSAT continues to be the communications standard in the maritime market. And with emerging High Throughout Satellites (HTS), VSAT adoption is projected to double from 12,300 vessels to 24,600 vessels, according to Comsys. Comsys also predicts service revenue across the maritime industry will hit $1.2 billion by 2016.
The information graphic below explores four markets within the maritime industry: Cruise lines, offshore oil and gas, fishing and commercial shipping. These markets present key opportunities to service providers.
For traditional maritime VSAT markets like cruise lines and offshore oil and gas, growth is tied to a proliferation in applications and a surge in data usage. And HTS will open the door further by lowering bandwidth costs enough to encourage greater use in high bandwidth applications like HD video and high-res imaging.
Emerging markets like fishing and commercial shipping will be especially impacted by HTS. These markets have been slow to adopt VSAT due to cost constraints. Improved economics will enable them to begin using basic voice, data and video applications.

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
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:
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
