Inmarsat’s GX Satellites Are Now Fully Operational

From Satnews

Inmarsat is reporting that the third satellite of the company’s new Global Xpress fleet, Inmarsat-5 F3 (I-5 F3) which was launched August 2015, has successfully completed all its in-orbit testing (IOT)—the spacecraft is now fully operational and station-kept in final orbital position.

With this latest accomplishment, all three Global Xpress (GX) satellites have now achieved full operational capability to support government missions, which started on December 1, 2015.  GX Government services can be competitively procured from a wide array of authorized Value Added Resellers.

Intelsat Exec Says Sky Perfect JSAT Deal Took 18 Months To Do

From Via Satellite

Intelsat’s latest EpicNG deal with SkyPerfect JSAT was not easy to do and in fact took well over a year to complete, according to Bruno Fromont, senior vice -president of strategy and asset management at Intelsat. Fromont told Via Satellite that Intelsat had been working on this deal “for quite some time” and that it had been “18 months in the making.”

Intelsat and Sky Perfect JSAT announced earlier this month that they had signed a definitive agreement to form a joint venture that will launch a new satellite with optimized C-band and high throughput Ku-band capacity to satisfy the growing mobility and broadband connectivity demands in the Asia-Pacific region. To be known as Horizons 3e, the satellite is based on the Intelsat EpicNG high throughput design, which, upon launch, will complete the global footprint of the Intelsat EpicNG next generation platform. The satellite will be stationed at the 169 degrees east orbital location with a launch expected in the second half of 2018.

Sky Perfect JSAT is a long-standing partner of Intelsat, and given the history that the two operators share, the deal is perhaps not a surprise. Also, with Japan being such an important market and an overall telecommunications hub, the partnership makes a lot of sense for Intelsat.

Fromont said Intelsat felt the partnership model made the most sense for its first High Throughput Satellite in Asia. Continue >

Stirred, Not Shaken

By Dave Davis, Sr. Systems Engineer, iDirect Europe

Global MilSatcom was a real success last week with more people than ever gathering to learn about developments in the MilSatcom world. As predicted, the Airbus evening event on day two was a real highlight and this year the choice of venue was inspired. Just after the release of the latest James Bond Film, Spectre, we went to the London Film Museum and had a reception in the thrilling Bond in Motion exhibition.

Bond is known for his love of Martinis, shaken, not stirred. But after Global MilSatcom, I felt the other way around – Stirred, not shaken. I’ll explain.

I wasn’t shaken because there wasn’t really anything to be shaken by. One of the main themes was the need for greater collaboration between the defence organisations and the commercial satellite sector. Not a groundbreaking observation really. Partnerships are nothing new to iDirect and we’ve been working hand-in-glove with defence organisations for decades, developing products and platforms that have the defence and security community’s needs at their heart.

With market leading security features, Network Management System (NMS) and Quality of Service (QoS), iDirect have engaged with the defence users to provide a capable platform, which is resilient and affordable. The QoS options allow separation of welfare traffic and operational traffic and allows managers to distinguish between a myriad of levels of priority and allocate valuable resources as needed, guaranteeing the levels of service required. The NMS is the most powerful in the industry, allowing commercial partners and end users varying levels of control and monitoring. And the security with TRANSEC and FIPS-140-2 protection is second to none. With the introduction of the 9000 series remotes, the separate TRANSEC module allows for fast re-certification, meaning defence forces can keep pace with the technological advances and stay abreast of features the commercial sector enjoys, whilst maintaining security and accreditation.

Getting Real: The Remote and Rural Reach of Satellite

Today, advances in satellite technology and wireless infrastructure are enabling mobile operators to reach new subscribers and expand their networks into remote and rural regions of the world in a smart, profitable way.

Let’s focus on one area where new wireless infrastructure is making an impact: small cells. When coupled with HTS (High Throughput Satellite) and advanced satellite ground infrastructure technology, small cells provide an efficient, targeted alternative for remote and rural coverage compared to large macro cells—at the same level of investment.

Small cells are being deployed globally in urban areas, as opposed to using large macro cells, in order to offload data traffic in congested areas. Based on their size, small cells are easier to deploy, require less energy and need less infrastructure at a site. Building on the same small cell infrastructure being used to connect urban sites, the business case for connecting rural and remote sites is changing.

A recently published white paper by Real Wireless analyzed rural populations in more than 200 countries, along with various rural areas within the United States. The goal was to assess the potential benefits of small cells in bringing coverage to rural and remote populations worldwide.

At iDirect, we wanted to take this analysis a step further. So we commissioned Real Wireless to augment the findings from this study and independently assess the benefits to operators of using satellite backhaul on remote cellular sites.

Our goal was this: Given the option to deploy small cells with satellite backhaul as a complement to traditional macrocells, rather than just choosing macrocells alone to extend coverage, would mobile operators be able to extend their reach with the same investment? Read More

The New Imperative: Innovations on the Ground Aligning with HTS Opportunities in the Sky

High Throughput Satellite (HTS) advances in throughput are well understood at this point. Now, the demand for innovation shifts back to ground infrastructure. In particular, how will ground infrastructure technology providers advance their platforms to enable satellite operators and service providers to best capture the HTS opportunity?

At iDirect, our goal is to ensure that service providers can leverage their investment in the existing ground infrastructure while taking advantage of HTS opportunities in the most profitable way. However, these new HTS satellite architectures come with a new set of challenges for the ground.

In a brief video, Designing a Ground Infrastructure Platform for HTS, Greg Quiggle, VP of Product Management, identifies the areas of innovation that we are looking to do at iDirect to enable both of our platforms iDirect Velocity™ and iDirect Evolution® to be optimized for HTS. He outlines the areas around scalability on the hub, higher performance on the remote side and scaling and automation on the network management side.

Here are some key considerations that we are looking at in the video:

HTS offers higher throughput rates than traditional broad beam satellites. Enabling these advances on the hub side means that the platform infrastructure must handle higher aggregate symbol rates, deliver more efficient modulation and coding techniques, and saturate larger transponder sizes. The hub infrastructure must be able to manage increasingly more beams, more frequencies, more MHz and ultimately many more carriers on the service providers’ network. The other consideration for the hub side is adaptivity achieved by Adaptive Coding and Modulation (ACM) and Adaptive TDMA to maximize data throughput and optimized traffic in changing weather conditions and satellite link degradations.

Mobil Satellite Technologies Launches New 10 Mbps x 4 Mbps iDirect Broadband Service In USA

From PR Newswire

Mobil Satellite Technologies, a leading provider of mobile and fixed satellite Internet connectivity services, announced today that it has launched a new high-bandwidth 10 Mbps download X 4 Mbps Ku-Band service for use anywhere in the North America.

This iDirect compatible service offers a great solution for users requiring high-throughput satellite performance while leveraging existing Ku-Band hardware. Ku-Band service operates with longer wavelengths, giving Ku-Band a superior ability to perform through inclement environmental conditions.

The Mobil Satellite Technologies satellite network has been configured to support this new service with 1.2 meter antennas with only an 8 Watt BUC, which are now available in a small, fan-less form factor that no longer require auxiliary power supplies that allows a simple replacement of the existing BUCs on almost any mobile or fixed 1.2 meter VSAT antenna.

Kirk Williams, Director of Sales at Mobil Satellite Technologies, commented: “This new service gives users the ability to upgrade to an extremely robust satellite broadband service while continuing to use their existing Ku-Band equipment. Before this new service, users would have had to buy all new Ka-band satellite hardware to have access to service plans offering these kinds of data speeds.” Continue >

Up To The Task Of Providing Greater Resiliency In HTS

Nikola-KromerBy Nikola Kromer, Senior Director Product Marketing, iDirect

The need for greater resiliency to your High Throughput Satellite (HTS) network is apparent: Just ask Denis Sutherland, who pointed to five reasons in his last blog.

As he outlined, HTS satellite architectures oftentimes drive a higher concentration of hub equipment at the central gateway site. Higher throughputs on HTS drive larger scale and service complexities resulting in massive networks with thousands of remotes managed by fewer gateways. Scaling many more networks and customers from fewer gateway locations introduces a greater need for network resiliency, and more specifically, teleport and gateway reliability.

Protecting the network from service degradation, service interruptions or even catastrophic events is key to ensuring a very high availability and reliability of the HTS network. And since quite a few HTS constellation leverage Ka-Band, where its frequency has a higher susceptibility to rain fade compared to Ku-band and C-band, maintaining consistent network availability under all weather conditions requires special features.

At iDirect, we have designed our platform to have built-in high availability on all aspects of the hub infrastructure ranging from superior line card availability and hub component redundancy, to rain diversity and all the way to complete gateway redundancy. Read More

5 Reasons HTS Networks Need To Be More Resilient

By Denis Sutherland, Director of Business Development, iDirect

It has always been critical to ensure that satellite communications infrastructure remain online, and operational. High Throughput Satellites (HTS) introduce many reasons for redundancy and resiliency—five reasons, to be exact. Let’s take a look.

HTS 5 reasons final

1)      Gateway Architecture

One of the critical factors that impact satellite operators and service providers is the architecture of a high throughput satellite. Centrally located hub infrastructure accessing a gateway beam, a feeder link, leads to an increased amount of traffic generated from a single teleport, which equates to greater risk of network failure or service impact from uplink degradation. This is particularly relevant in the case of Ka-band, as its frequency has a higher susceptibility to rain fade compared to Ku-band and C-band. Since Ka-band frequencies are particularly prone to rain fade, a network must also leverage adaptive modulation techniques, such as Adaptive Coding and Modulation (ACM) and Adaptive TDMA, to achieve the maximum data throughput and optimized traffic in changing weather conditions.

In many cases satellite operators that are managing the teleport will make provision for service degradation such as for weather so severe that ACM can’t protect the link, or for a failure in the teleport. This will also drive operators to consider smarter gateway diversity, ensuring that failure in one gateway, will be backed up in a different location. This is the case with Telenor’s Thor 7, as explained here, which has two uplinks in Norway to achieve carrier-grade availability.

2)      Scale of Networks

In a previous blog I considered how HTS networks will increase in scale. There will be additional network infrastructure with HTS, due to increased numbers of beams, more terminals, and higher data rates. As the networks grows the need for reliable network infrastructure increases. Read More
