RACELOGIC – Integrate le frequenze Galileo nel software di simulazione SATGEN

SatGen now with Galileo

The latest update to our SatGen GNSS simulation software for PC now incorporates Galileo RF simulation.

Designed to create a GNSS RF I&Q or IF data file based on a user-generated trajectory file, the updated software can now accurately simulate the European Galileo GNSS satellite constellation alongside existing GPS, GLONASS, and BeiDou RF signal generation.

The full range of Galileo frequencies that SatGen can simulate are Galileo E1 B/C, E5a, E5b and E6 B/C (see table below for further information).

Mark Sampson, LabSat Product Manager – “Given the vast improvements in navigation and timing that Galileo has brought to its global users, we extremely excited to be releasing a version of SatGen that allows engineers to generate Galileo-specific scenarios for their test procedures.”

Other changes to the software include various UI tweaks, performance optimization, and fixes. SatGen users can download the software update here.

NOVATEL – 7.07.01 firmware release for our OEM7®, PwrPak7® and SPAN® CPT7 products

NovAtel® is pleased to announce the 7.07.01 firmware release for our OEM7®, PwrPak7® and SPAN® CPT7 products. Our OEM7 technology provides exceptional positioning availability using signals from all constellations and frequencies to deliver reliable autonomy and positioning.

The following key benefits are now available in the 7.07.01 release:

• Faster satellite acquisition and at lower C/Nos decreases the time to first fix in both cold and hot starts • The SPAN Marine Profile simplifies receiver setup for applications in marine dynamics and improves the heave performance of the receiver.
• The SPAN Rail Profile improves position accuracy over long GNSS outages in a rail environment

• SPAN improvements of up to 20% in the horizontal position and up to 8% in the vertical position

A full listing of all changes is available in the “What’s New” document that is included with the firmware download.

RF and microwave for EMC testing

We just wanted to share with you the feedback we are getting from customers such as Airbus and BAE Systems about our world-class Sentinel 3 RF over fibre system.

Here are some of the highlights from our customer feedback:

• An additional 9dB of measured dynamic range
• Measuring signals at -115dBm and even detecting at -120dBm
• Reducing the number of measurement “batches”, due to low crosstalk and layout flexibility.
• Reduce the total test time by HALF, including setup time.

Doesn’t that sound like it could have a huge impact on your EMC testing?

Sentinel 3 – Speed, Flexibility, Certainty

• Faster test setup
• 1 or 8 input transmitters
• Receivers – 1, 2 or 6 input
• Auto thermal compensation
• Multiple performance modes
• PC control via USB or Ethernet

Galileo Service Alert

Please be advised that there is a system advisory currently in place for all Galileo users. It was issued on July 11th, 2019 and does not have specified end date.

Observed system behavior shows that the Galileo INAV and FNAV ephemeris has not been updating. During this time, NovAtel receivers will continue to track Galileo signals, but without a valid ephemeris, the signals are not included in the position solution.

Products Affected:
All NovAtel OEM6 based and OEM7 based receivers that are configured to track Galileo signals.

Solution:
Once the Galileo service returns to normal and transmits ephemeris information, NovAtel receivers will revert to normal operation.

Please refer to the NAGU provided by the European Global Navigation Satellite Systems Agency for updates: https://www.gsc-europa.eu/notice-advisory-to-galileo-users-nagu-2019025

Avoiding instrumentation interference and signal losses at high frequencies

As part of an aircraft’s certification for flight, aircraft must demonstrate safe operation within a range of environmental conditions. This includes Electromagnetic Environmental Effects (E3) which, for civil aircraft, include High Intensity Radiated Fields (HIRF) and Lightning. Both HIRF and lightning testing involves either (i) high level whole aircraft testing or (ii) a hybrid test method of low level aircraft testing with high level equipment testing.

For either test method, fibre optic links (FOLs) are essential to prevent compromising the measurements. For example, during low level swept current and field measurements, FOLs are employed to provide signal gain and isolation from the generated EM environment, typically from 10kHz to 1GHz.

Prevent instrumentation influencing the aircraft’s transfer impedance

Instrumentation should not influence the aircraft’s transfer impedance whilst it is exposed to RF fields or simulated lightning – for example, currents that degrade the airframe shielding. Interconnecting cables that pass from the external environment to the internal aircraft environment will impact measurements, for example RF current can flow on the cable shields. It is important therefore that signal cables are not used to connect the external instrumentation to the field/current/voltage probes installed within the aircraft, whilst performing frequency or time domain measurements. This is particularly significant over the 10kHz to 1GHz frequency range, where cable coupling dominates the leakage mechanism into the aircraft under test.

Avoiding signal loss at high frequencies

The external instrumentation must be outside the measurement area which with large aircraft may lead to a separation distance of tens’s of metres. Signal loss then becomes a factor at higher frequencies. Such signal loss is also avoided by the use of a FOLs. A typical aircraft low level swept current measurement would require signal cables of 40 to 50 metres, introducing significant losses. FOLs are typically used with 100 or 200m link lengths, permitting signals to be coupled from the transducers installed on the aircraft to the measurement equipment for even large transporter/passenger aircraft, requiring fibre lengths of over 100m.
