Experiments carried out at Spirent in August 2015 by Spirent and Calnex

Using GSS 6700 GNSS Simulator and SimSafeTM, Spirent’s GNSS Spoofing test bed, to set-up attacks on several timing receivers and then alter the timing information received by the target receiver

Objectives: How do timing receivers react to fake GPS signals? When spoofing is in progress, do current receivers provide warning indications or flag problems? Should users of timing systems be worried? What safeguards could be implemented?

Results will be presented in a paper at ITSF 2015, 02-05 November, Edinburgh

Calibrating Timing Error for PRTC (primary reference time clocks)

Background

Time and phase is a synchronisation problem in modern networks.

Time Error Requirement

(with respect to ideal

reference)

Typical Applications

1 ms - 500 ms Billing, Alarms

5 ms - 100 ms IP Delay monitoring

1.5 ms - 5 ms LTE TDD (cell >3km)

1 ms - 1.5 ms

UTRA-TDD,

LTE-TDD (cell

3Km)

Wimax-TDD (some configurations)

1 ms Wimax-TDD (some

configurations)

If time error is not satisfied

Call interference

Dropped calls

Packet loss/collisions

Reduced spectral efficiency

Streaming interruption (video broadcast)

Poor signal edge of cells

Location-based services lose accuracy

Lower data speeds

GPS/GNSS satellite-based systems

Provide 1PPS signal

Time-of-day (ToD) calculations for next-second rollover

Time and phase references


Recommendation ITU (International Telecommunications Union) G.8272 specifies error allowed at the time output of the

primary reference time clocks (PRTCs) for time and phase synchronisation in packet networks, such as LTE.

3 specifications:

Calibrating Timing Error for Timing Receivers

Example: 4G LTE Application

1. Comparison to a PRC frequency standard

• Only addresses phase wander (i.e. dTE)

• Cannot verify max|TE| value – Inadequate

2. Comparison to a reference receiver

• Addresses both phase wander and max|TE|

• Uncertainty of the reference receiver may be too

high – Inadequate

3. Comparison to a national time standard

• Addresses both phase wander and max|TE|

• Only available from a certified national time

laboratory – Inadequate

Calibrating Timing Error for PRTC


Test Cases to check software algorithm in receiver.

GPS Satellite number changing effect

: Force satellites SVID into different channels. Checks algorithm to see which satellites are used for timing.

: Adding/removing satellites can have affect on frequency synchronisation in receiver.

GPS Multipath and fading effect

: Introduce these effects for complex scenarios of receiver location. i.e. surrounded by urban tall buildings.

GPS Leap Seconds

: Important to test for introduction of leap seconds if correct warnings and actions occur when event happens

– requires navigation data modification.

Above tests performed for other constellations (in event of GPS failure)

: Glonass system failed in April 2014 due to bad ephemerides data uploaded to satellites causing broadcast

of corrupted data for 11 hours. Such an event was described “impossible to happen”. Systems need to

prepare for such cases.

Tests for switching between constellations



Important tests to check software algorithm in timing receiver

GPS Satellite

Force satellites SVID into different channels. Checks algorithm to see which satellites are used for timing.

Add different tests/ Keep running for as long as possible / Repeat / make changes

Tests

1. All Satellites off

2. Turn on channels 1 to

6

3. Force satellite 13 to

CH: 1

4. Force satellite 16 to

CH: 4

5. Turn all satellites off

2 53 & 4




GPS Multipath and fading effect

Introduce these effects for complex scenarios of receiver location. i.e. surrounded by urban tall buildings.

Tests

1. Reduce power on

channels 5 and 6

2. Change signals

from satellites 16

and 22 to multipath

1 2




GPS Leap Seconds

Important to test for introduction of leap seconds if correct warnings and actions occur when event happens.

Receiver manufacturers do not always test this.

1998: Mobile Phone Blackout in USA – time change was outside network tolerance

2012: Qantas Airline over 400 flights by 2 hours – operating system using UTC did not update correctly.

Tests for switching between constellations

Perform tests with both GPS/Beidou satellites on, turn off all Beidou satellites to see if receiver will start tracking GPS.

Force GPS to track – do the same with Beidou.

Topology Emulation

Testing is no longer limited to packet blasting or single functionality scenarios…

Testing a real network, takes a real network to test…

Spirent TestCenter Topology Emulation allows testing exactly how the device would perform in a real network

• Avoid performance surprises not exposed by less stressful unrealistic test plans

• Testing subsystems independently does not expose performance problems caused by the subsystems interacting and competing for resources

• Topology emulation also allows testing to occur when the network is changing

Testing Scenario Examples:• Video traffic (server and clients) over mVPN

• Multi-hop BGP with fully emulated intermediate nodes

• Stateful traffic (ALP) over any topology

• Routing over Access

• MPLS IP VPN over Access (remote PE connected via DSL)

• RFC2544 over routing

• RFC3918 over mVPN

• RFC2889 over VPLS

With our advanced network emulation you can take a topology, decide what you want to test and

easily build it up in Spirent TestCenter


STC unique Layer 2/3 Dataplane features
