4. How can GNSS Testing Help?
Real Customer Examples

5. GNSS Simulator Assists Galileo; Orbit Correction
Example 1: How GNSS testing can help?
Identify Problem:
Aug 22, 2014: Two Galileo satellites fail to reach correct orbit due to hardware design failure in rocket fuel line.
Test Solution:
Spirent’s engineers generated a special service release for ESA of our PosAp software.
This enabled ESA engineers to simulate different candidate orbits, to simulate the different outcomes
Problem Resolution:
“We iterated with Spirent to get the patch we needed in order to simulate GSAT 0201/ The patch provided by Spirent was instrumental for the Scenario C assessment (this including GSAT 0201 In orbit Testing preparation).”
Marco Falcone, Galileo Programme Lead, ESA, Jan 2015

6. Robust PNT Audit Quantifies Impact of Scintillation and Space Weather
Example 2: How GNSS testing can help?
Identify Problem:
Communications broadcasts for a national network were being affected by GPS clock drop-outs
The company was unsure what was causing the drop-outs, and how to solve the problem
Test Solution:
Robust PNT test pack including interference and space weather scenarios
Test report provided that identified behavior of the hold-over to back-up clock during GPS distruption
Problem Resolution:
GPS hold-over was not reverting cleanly to GPS after outage
Firmware update solved the issue
Now recommending re-testing against updated tests with new events

7. Aerospace Application
Example 3: How can GNSS testing help
Identify Problem:
How to test GNSS performance during different phases of launch
Test Solution:
Simulation with changing obscurations, in real-time, in GNSS simulator (GSS7000/9000)
SimGEN software allows different antenna patterns for different phases of launch
Atmospheric modelling changes through different phases of flight
Problem Resolution:
End-to-end mission scenarios modelled in the lab, using real receiver hardware with simulated antenna placement and environmental effects
Reduced costs and improved mission confidence
