Boeing signs off anti-jamming tech that keeps satellites online

(2023/03/08)


Boeing said on Tuesday its anti-jam ground-based satellite communications system had passed the necessary tests to validate it for use in the U.S. Space Force’s Pathfinder program.

The aerospace giant hit the milestone by demonstrating the system, called the Protected Tactical Enterprise Service (PTES), with an on-orbit operational satellite. Engineers tested what would happen if field-deployed equipment was accessed via the US military's jam-resistant waveform, the Protected Tactical Waveform (PTW).

The tests proved PTW was resistant to jamming but also validated hardware and software integration between PTES and the Department of Defense’s satellite communications (SATCOM) architecture.

Now that all this testing is done and dusted, the US Space Force plans to deploy PTES over the government’s Wideband Global SATCOM (WGS) fleet, of which Boeing is also the prime contractor, where it will provide PTW processing over the fleet sometime in 2024.

Space Force's intention is to prevent adversaries interfering with signals sent to military satellites, even in hostile environments. China and Russia both [4]possess the capability to disrupt satcoms, recognition that orbital assets have a critical role in terrestrial conflict and degrading them is therefore a likely tactic.

While the initial user of the anti-jamming tech is Space Force, commercial satellite operators are another likely customer.

Afterall, the goal of the Pathfinder program, according to Space Force's Space Systems Command (SSC) is to “demonstrate affordable bandwidth acquisition by gaining long-term access to transponder assets from commercial satellite providers,” presumably without worrying about being jammed.

The program [9]launched [PDF] its third mission in early February – a transponder known as Pathfinder 2 that went on board Hispasat’s Amazonas Nexus geostationary remote internet providing satellite.

“The ability to augment the current wideband constellation combined with the potential to introduce resilience, will greatly enhance our ability to stay connected in contested environments,” [11]said chief of tactical satcom acquisition delta at Space Systems Command Charlotte Gerhart.

“By augmenting current systems with PTES, which is designed to be forward and backward compatible with government and commercial systems, the U.S. DoD and its allies are able to meet the challenges of an evolving battlefield,” said Boeing VP of government satellite systems Troy Dawson.

Boeing is also building a $1.8 billion space-based PTW hub for sensitive and classified information called the Protected Tactical SATCOM Prototype (PTS-P). The $383 million PTES contract was awarded to Boeing in 2018. ®

Yes but...

Neil Barnes

This is all very well, but how does it work? We don't need the details but it would be nice to see some sort of explanation. This is a tech site, after all...

Re: Yes but...

”we have a method of preventing disruption to our satellite communications, here is how we do it. Hope you find this information useful in your work to develop a new jamming method to get round it”

Security through obscurity?

Re: Yes but...

It uses the well known 'foolpoof' security by obscurity system.

How it works!

"Data protection is achieved by using a bit-cover process before frames are grouped into information blocks for encoding. The DVB-S2 short block code [4] is used as the primary forward-error-correction (FEC) mechanism. This provides a fixed 16,200 bit encoded block length based on a combination of LDPC and BCH techniques with resulting rates ranging from 0.19 to 0.88 and supporting approximately 10 dB of link SNR fluctuation for a given symbol rate and modulation.

Codeword data is grouped into symbols and multiplexed across many hops, where a hop is the duration of time a transmission stays at one frequency before “hopping” away to another frequency. The hops are then permuted in time. Together, these features provide increased resistance to transient jamming or interference."

Yes yes yes, very thorough, but how does it resist percussive jamming?

Re: How it works!

TJ1

It replaces the Jam with Honey, so they use percussive honey instead.

Re: How it works!

Thank you.

Re: Yes but...

They have installed wipers on the satellites parabolic antenna and have a ground crew on standby for the one on earth. Then they can just clear the jam off easily.

All well and good but one inverse tachyon field and it all goes tits-up.

We're jammin', jammin', and I hope you like jammin' too
