Daylight version of the QPD
In its daylight version, the QPD doesn’t use a pedestal mount and is not a surveillance equipment. It is intended to be aimed at the threat visually detected with his eyes, without binoculars, by a look-out or by an operator of the Weapon Direction Platform (WDP) Visual.
After the direct visual detection, the operator points the pistol handgun shape Sighting Unit towards the target direction and transmits the targeting information to an electro-optical device, to a decoy sub-system, to a weapon system, or to the Combat Management System, by a trigger.
The QPD designation data (True Bearing and True Elevation) can also be sent to an electro-optical sensor in order to spot the direction of alert found by a look-out.
In the basic version of the QPD, the coordination between the Operations Room warfare modules, the WDP Visual Officer, and the QPD operator is done by voice.
However, due to its wide connectivity (see next section of this paper), the QPD can be connected to a display unit installed on the WDP, or on the bridge, in order to present feedback information related to the results of the pre-designation sent to an electro-optical device or the designations made to the weapon systems by the QPD.
It should be noted that the QPD presents on a LCD display at the rear face of its Sighting Unit, the true azimuth and elevation sent to the Combat system equipment, and needs to be connected to the ship navigation system.
The QPD has been designed to be operated through a reflex action with one hand, by a right-handed or a left-handed operator, and also by an operator wearing glasses or gloves.
The typical cycle of operation of the QPD is:
- Visual detection of the target ;
- Acquisition through the aiming device of the Sighting Unit ;
- Periodic calibration of the Sighting Unit (after a typical use cycle of 3 minutes), which performs in less than 1 second the correction of the gyrometers drift.
Night version of the QPD
In this version, the QPD is fitted with IR binoculars or a Light Intensifier Device.
