1. Attacks on Critical Infrastructure
And what can we do about it

2. So – What Are We Afraid Of?
In the busy control center
Sync systems, at best, are monitored on very “side-screen”
No one (except Focus of course) remembers where the antennas are
Sometimes, not even where the server is

4. Climb On Roof With Internet Jammer

5. Focus Telecom Confidential
Turn It On and Hide It

6. What Do We See When This Occurs?

7. Focus Telecom Confidential
What Do We Do Then?
Check antenna
Check lightning arrestor
Check cables
Replace antenna?
Replace lightning arrestor??
Replace cable???

8. So, What Can Be Done? Improved HO
Improve the holdover capability of your system
Rubidium based
24 hours
Upgraded OCXO
24 hours
In > 1hr, Rb drift < 50ns
Jamming begins –
GPS is cut off
In > 1hr, standard OCXO drift < 720ns

9. Focus Telecom Confidential
So, What Can Be Done? GNSS
Multiple constellation SW license
Supports simultaneous GPS & Glonass
Very effective for narrow band GPS jammers

10. So, What Can Be Done? infiniDome’s GPSdome
The only commercial front-end GPS protection in the market
Null-steering antenna module
Rejects high-powered illegal signals like jamming and spoofing and maintains only the true GPS signal reception
Next revision (EOY 2018), will send down to the server an ALERT when the attack is happening

11. GPSdome Protection For Same Attack
Deploying two antennas enables the null steering algorithm
With the jammer turned on
At exact same location as before
Focus Telecom Confidential

12. GPSdome Successfully Protects Against Attack
When jamming begins
Immediate impact of about 10dB in the SNR
But the signal remains strong and stable
10 dB on average

13. The Microsemi BlueSky Protection
Back-end GPS protection
Leverages Microsemi’s Autonomous Timescale algorithm to detect spoofing
Continues providing a “regular” GPS signal when jamming or spoofing detected
