The VECTOR-400 is a cutting-edge, robust and dependable autopilot, with built-in physical and logical redundancy. Designed to comply with MIL-STD standards required by many Departments of Defense (DoD), the VECTOR-400 is now the Flight Control Computer (FCC) of choice for aerial target applications.

The Professional's Choice for Aerial Targets

Specifically designed to meet the special requirements of aerial targets: catapult launch, highly dynamic maneuvers, high speed flight, sustained +3G maneuvers, parachute recovery, etc.

Fully Automatic Operation

The VECTOR-400 executes the flight completely automatically, from take-off to landing. The operator is able to define the operation and execute it autonomously, but can also modify the operation in-flight.

GNSS-Denied Navigation
GNSS-Denied Navigation

Exceptional performance in GNSS-denied environments and when there is a jamming threat. High quality components and an EMI/EMC resistant design (tested to MIL-STD 461), together with advanced estimation logic, serve to mitigate the impact of certain high-power signals and allow precise dead-reckoning navigation even when a reliable GNSS signal becomes unavailable.

Datalink Independent

Advanced onboard software means that the mission can be carried out even if the datalink becomes unavailable or fails.


When a radar altimeter is installed, the VECTOR-400 can use readings from the unit to control high speed, sea-skimming flight at altitudes down to 7 m above surface level. The system also features automatic abort logic which means the mission can be safely terminated at a predefined safety distance from the target vessel. Such safety features can also be triggered automatically by preset alarms.

Compact and Easy to Integrate

Reduced size and weight allow straightforward integration into the platform's avionics package using a robust Amphenol military grade, twist fit connector. Integrated datalink options are available.

The VECTOR-400 is a compact autopilot designed specifically for Unmanned Aerial Targets (UAT). Its robust enclosure and military grade connector are designed to withstand the toughest environmental conditions and conform to MIL-STD 810 and MIL-STD 461. 

It has built-in physical and logical redundancy, allowing it to survive all individual sensor failures and even jamming attacks while maintaining accurate estimates of attitude and position. Advanced algorithms, such as stall protection and an automatic gliding capability, ensure flight safety in case of engine failure. 

The VECTOR-400 incorporates UAV Navigation’s proprietary Air Data Attitude and Heading Reference System (AD-AHRS) and Inertial Navigation System (INS), providing precision attitude information and enabling reliable navigation even in the most demanding environments. The outstanding AHRS means that the VECTOR-400 delivers great performance in GNSS-denied environments (<30 m/min drift) and also when executing highly dynamic maneuvers. 

Every unit is checked in accordance with UAV Navigation's meticulous calibration processes before passing Quality and final acceptance tests; only then is it delivered to the customer with its individual Certificate Of Conformity.

UAV Navigation has designed the VECTOR-400 to conform with MIL-STD-810 and MIL-STD-461. Hardware and software design and development are in accordance with DO-178, DO-254 and also ASTM F3201-16 - one of the only certifications geared towards unmanned aircraft.

When a radar altimeter is installed, the VECTOR-400 can use readings from the unit to control high speed, sea-skimming flight at altitudes down to 7 meters above surface level in order to provide realistic anti-ship missile threat emulation and training.

Not all autopilots are able to control highly dynamic platforms; even less are able to perform special maneuvers such as high speed, sea-skimming flights.

Flight Modes:

Brief Description
The operator pilot has full control over the platform.
The autopilot will execute the take off maneuver from standstill to the point where it can transition safely to AUTO flight.
AUTO mode executes the programmed Flight Plan (FP) based on waypoints. 
The autopilot flies to specified coordinates, maintaining current altitude and airspeed.
The autopilot executes a circular pattern around the location where LOITER mode is engaged.
The autopilot will command the aircraft to fly to a preset Safety Altitude. Once achieved, it will automatically switch to LAND mode.
DIRECTED The autopilot maintains current IAS, altitude and heading.
The autopilot executes the land maneuver, from its current flight mode to a predefined and even relative landing site.
The operator is able to over-command directly from the joystick/gamepad.

UAV Navigation is a leading autopilot manufacturer with extensive experience in the aerial target market. The company's range of autopilots for aerial targets means that customers can choose from cutting-edge, highly advanced flight control solutions for the most demanding platforms, down to more straightforward systems for simpler targets which require a more cost-effective autopilot. Although UAV Navigation offers a range of autopilots, the flight control system and Visionair Ground Control Station (GCS) software behind all of them is the same, providing the same reliability and dependability, and minimizing operator training costs.
