Decades of relative tranquility in space have come to an end. The possibility of state-on-state conflict has become part of military planning, making flexible and continuous connectivity more critical than ever for defence forces around the world. The cybersecurity threat to SATCOM has also increased, both from hostile governments and non-state actors.

These new realities are forcing a change to the status quo. NATO for example has recognized these threats, and has increased its budget for space capabilities and coordination with the goal for alliance members to spend at least two percent of gross domestic product on defense by 2024.

That target will be met by eight NATO countries this year, up from three in 2014, and by at least 15 alliance members by 2024. Of course, these funds need to be spent wisely.

Fortunately, open yet secure architecture has already been developed in collaboration with private industry, enabling resilient ISR functionality with unprecedented performance and flexibility.

Stove-piped encrypted communication networks are giving way to secure common-network domains. However, technicians now must find a way to feed better decision-making systems using open systems where information is fused from multi-domain sensors.

As communications becomes a capability rather than a platform, secure connectivity will be fundamental to enabling new capabilities in space, turning huge quantities of SATCOM data into actionable intelligence. New commercial technology such as high-throughput satellites (HTS) has transformed space architecture in commercial markets, fundamentally changing what had been a predictable global market.

Countries of all sizes can leverage the greatly enhanced capabilities and connectivity that this new technology can provide. HTS satellites like Intelsat EpicNG provide up to 300 percent more throughput than existing wideband satellites enabling small mobility terminals. The high-throughput, high-frequency re-use, multi-spot design of these satellites also offers enhanced protection features over wide beam satellites.

In order for an adversary to jam a satellite, for example, the jamming device must be located within the same beam as the satellite signal. The spot beams utilized on EpicNG are significantly smaller than spot beams on traditional commercial satellites, resulting in a much smaller area from which one can attempt to jam.

In contrast to widebeam satellites which typically have beams between 36MHz and 72MHz wide, a nominal Intelsat EpicNG beam is 125 MHz wide allowing for greater jamming mitigation capabilities over traditional satellites. The wider the satellite transponder, the greater the allowable spreading and the greater the protection provided. Similarly, in a wider transponder, there is more room for hopping, if that protection technique is used.

Intelsat EpicNG is an open architecture system and backward compatible, allowing countries the flexibility of defining their own network topology and hardware. This is a significant distinction from other HTS platforms that are purpose-built solutions servicing homogeneous sets of users via a closed architecture.

The Polish government recently demonstrated how it intends to leverage the innovation of the commercial space industry. According to a recent article in Space News, the Polish Space Agency (POLSA), said that new satellite projects will be carried out with "significant involvement of the Polish space industry."

"In POLSA's opinion, the level of technological development of the solutions developed by the entities of the Polish space sector will allow [the sector] to implement a significant share of the UV satellite and SAR microsatellite projects in Poland," said Col. Piotr Suszynski, Vice President for defense at POLSA.

"The domestic companies and scientific and research institutions have developed full or partial competencies in the fields of, among others, electronics, mechanics, automation, robotics and steering theory, as well as ground and space software."

The same forces that have transformed terrestrial IT have fundamentally changed space from a defence perspective. Much of the new technology currently being deployed was developed by the commercial sector. These next-generation systems should be leveraged as nations re-evaluate the criticality of SATCOM in their defence strategies and budgets.

CBAS Space Vehicle Completes Launch Base Testing
Los Angeles CA (SPX) Apr 12, 2018
The Continuous Broadcast Augmenting SATCOM, or CBAS, Satellite completed launch base testing March 15 in preparation for the payload's scheduled launch aboard the AFSPC-11 mission. The U.S. Air Force is scheduled to launch the CBAS satellite and the Evolved Expendable Launch Vehicle (EELV) Secondary Payload Adapter (ESPA) Augmented Geosynchronous Laboratory Experiment (EAGLE) satellite on the AFSPC-11 mission aboard a United Launch Alliance Atlas V EELV from Space Launch Complex 41, Cape Canaveral ... read more
