Enclosure

Veronte is provided using an anodized aluminium enclosure with enhanced EMI shielding and IP protection. The total weight including a 900 MHz / 2.4GHz radio module is 190 g.

All Veronte versions share the same enclosure. The only difference is the distribution of the connectors on the panel (to make the connections go to the Connector Layout section).

Vibration Isolation

Although Veronte ultimately rejects noise and high-frequency modes of vibration with electronic filters, an adequate vibration isolation design can improve the performances and extend the lifetime of Veronte.

Veronte can be mounted in different ways in order to reject the airframe vibration. The simplest could be achieved by just using a double-sided tape on the bottom side of Veronte. Other ways may use some external structure which could be rigidly attached to the airframe and softly attached to Veronte (e.g. foam, silent blocks, αgel, etc…).

vibration-isolation

The user should take into account that wiring should be positioned in a way which allows avoiding vibration transmission from airframe to autopilot.

In cases where Veronte isolation is not viable, it is possible to use soft engine mounts. It is also recommended when there are other sensible payloads like video cameras or for high vibration engines.

Location

The location of Veronte has no restrictions. You only need to configure its relative position with respect to the centre of mass of the aircraft and the GPS antenna. The configuration of the location of Veronte can be easily configured using VerontePipe Software.

 

Orientation

The orientation of Veronte has no restrictions either. You only need to configure Veronte axes with respect to the aircraft body axes by means of a rotation matrix or a set of correspondences between axes. The configuration of the orientation of Veronte can be easily configured using Veronte Pipe Software.

Veronte axes are printed on the box and aircraft coordinates are defined by the standard aeronautical conventions.

Antenna Integration

The system uses three antennas to operate that must be installed on the airframe, one for radio communications and another for GPS positioning. Here you can find some advice for obtaining the best performance and for avoiding antenna interferences.

 

Antenna Installation
  • Maximize separation between antennas as much as possible.
  • Keep it far away from alternators or other interference generators.
  • Always isolate antenna ground panel from the aircraft structure.
  • Make that the antenna is securely mounted.
  • Always use high-quality RF wires minimising the wire length.
  • Always follow the antenna manufacturer manual.
GPS Antenna
  • Antenna top side must point the sky.
  • Install it on a top surface with direct sky view.
  • Never place metallic / carbon parts or wires above the antenna.
  • It is recommended to install it on a small ground plane.
  • The antenna wire must be installed avoiding to roll it and using big radius for turns.
Communication / Video Antenna
  • It is recommended to use Omni directional antennas.
  • It should be installed vertically on the aircraft.
  • Place it in order to maximise the LOS with the control station.
  • It is recommended to install it on a ground plane following manufacturer indications.
  • Avoid any element that could block antenna communications.

 

 

 

 

Be sure connecting SMA wires avoiding to turn the autopilot SMA Plug female connector because the antennas internal cables could be turned and damaged.

Pressure Lines

Veronte has two pressure input lines, one for static pressure to determine the absolute pressure and one for pitot in order to determine the dynamic pressure.

Absolute pressure connection on the aircraft is mandatory while pitot port can be obviated in some aircrafts, pitot port absence must be configured on Veronte Pipe software.

 

Pressure Intake
  • Pressure intakes must be located in order to prevent clogging.
  • Never install pressure intakes on the propeller flow.
  • Design pressure tubing path in order to avoid tube constriction.
Static Pressure
  • It is not recommended to use inside fuselage pressure if it is not properly vented.
Pitot Tube
  • Pitot tube must be installed facing the airflow in the direction of the “x” axis of the aircraft.
  • It is recommended to install it near the aircraft axis in order to avoid false measures during manoeuvres.
  • For low-speed aircraft it is recommended at least 6,3mm tubes for preventing rain obstruction.

 

It is recommended to use Embention dual Pitot tube, including both, static and pitot intakes.

  • Pitot pressure ranges are configurable on Veronte Hardware when placing an order, please review that selected sensor fits with aircraft speed.
  • To perform a Pitot test is sufficient a little blow into the tube. Blowing with energy could damage the dynamic pressure sensor of the autopilot.
