PPM TEST – Test EMC con il sistema a fibra ottica “Point2point RF Over Fiber” per le certificazioni di volo dell’aereomobile

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.

NOVATEL – Rilascio nuovo firmware versione 7.07.00 con modifiche ai comandi per tecnologia SPAN NOVATEL

SPAN Changes Scheduled for 7.07.00 Release

Background:
NovAtel’s SPAN (Synchronized Position Attitude Navigation) technology is widely known and used in applications requiring greater functionality and reliability, those that benefit from the seamless integration of GNSS and inertial data. With continuous development, especially coupling with the next generation OEM7 receiver; a list of improvements has been identified to better serve customers’ needs and simplify the interface communications. These changes will be rolling out in the upcoming future releases. Please plan accordingly.

Issue Summary:

DMI Interface Enhancement:
The DMI interface is simplified, allowing for simpler functional support and expansion in future releases for the use of multiple DMI’s. It also provides customers with the capability of starting the interface prior to the functionality being operational. Future multiple DMI support allows customers with more than one DMI sensor to benefit from the additional information. Velocity type input streamlines the passing of information to a NovAtel product for customers who have DMIs that produce velocity. Furthermore, this simplifies setting up a DMI sensor by removing the necessity to pass ticks/revolution and wheel circumference during a setup.

The result of these changes is that several logs/commands will be removed without deprecation. A maintenance version of Inertial Explorer will be released in tandem with 7.07.xx to support the changes proposed. Note that the WHEELSIZE log is no longer available, so customers will not be able to get the current estimated wheel circumference.

Current Type Proposed Type
WHEELVELOCITY* Command RAWDMI Log/Command
TIMEDWHEELDATA Log RAWDMI Log/Command
WHEELSIZE Log Removed
INSWHEELUPDATE Command Removed
SETWHEELPARAMETERS Command DMICONFIG Command
ENCLOSUREWHEELSENSOR Command DMICONFIG Command

* The WHEELVELOCITY command will still be accepted in a limited capacity. WHEELVELOCITY’s cumulative tick field will be mapped to a RAWDMI command for backwards compatibility.

 

Removal of OEM6 SPAN Command Support:
Several OEM6 SPAN logs and commands that have been deprecated since OEM7 launched and will no longer be supported. The replacement logs and commands in OEM7 have been documented in the OEM6 to OEM7 transition page in our documentation portal. A full list of logs and commands no longer supported is below (DMI changes included):

OEM6 OEM7 Replacement Type Reason
BESTLEVERARM INSCONFIG Log OEM7 transition
INSUPDATE INSUPDATESTATUS Log OEM7 transition

Additional CORRIMUS log / Deprecation of CORRIMUDATA(S):

The current CORRIMUDATA(S) logs will be replaced with the new CORRIMUS log. The CORRIMUS log is essentially the same log as the CORRIMUDATA(S) with an additional field added to output an IMUDataCount which counts the number of samples used in each log output. An example of the new log CORRIMUS is shown below. The CORRIMUDATA(S) log will remain working for those that choose to use it but will be removed from the official documentation.

Example log:

%CORRIMUSA,2023,340847.070;1,0.0000014373087865,-0.0000004823212266,

RACE TECHNOLOGY – Slow Speed GPS Accuracy Demonstration

Slow Speed GPS Accuracy Video

 

A demonstration of low speed accuracy of Race Technology SPEEDBOX-INS and GPS2 RTK systems. Running multiple low speed tests between laser barriers, set 20m apart using a class 1 tape measure. Speed accuracy is calculated from distance measurement discrepancy.

The results show that the SPEEDBOX-INS system is incredibly accurate even at low speeds. With the addition of the GPS2-RTK to the system, which improves positional accuracy, these is no noticeable improvement to speed accuracy.
