Aircraft Mounting

There are two versions of Veronte autopilot: with or without enclosure.

Enclosure

Veronte is provided using an anodized aluminium enclosure with enhanced EMI shielding and IP protection. A high reliability connector is also provided in this version. The total approximate weight is 190 g.

Mechanical Mounting

M3 screws are recommended for mounting. In saline environments such as coastal and oceanic, the screw material must be stainless steel.

Vibration Isolation

Although Veronte ultimately rejects noise and high-frequency modes of vibration with electronic filters and internal mechanical filters, there might be situation where external isolation components might be needed.

Veronte can be mounted in different ways in order to reject the airframe vibration. The simplest could be achieved by just using 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)

The user should take into account that wiring should be loose enough so vibrations may not be transmitted to Veronte.

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 GNSS antenna. The configuration of the location of Veronte can be easily configured using Veronte Pipe 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 different kinds of antennas to operate that must be installed on the airframe. 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 them far away from alternators or other interference generators.

Always isolate antenna ground panel from the aircraft structure.

Make sure the antenna is securely mounted.

Always use high-quality RF wires minimising the wire length.

Always follow the antenna manufacturer manual.

SSMA connections shall be tightened applying 1Nm of torque

For all-weather aircraft, insert SSMA lightning protectors.

GNSS 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.

For all-weather aircraft, insert SSMA lightning protectors.

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 aircraft, 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.
