The VECTOR-SIL (Software In The Loop) is a simulator which can be used to test the basic functions of UAV Navigation’s system.

Simulator SIl UAV Autopilot
Compact and Easy to Integrate

No complex hardware required. Perfect for its use during deployments.

VECTOR Simulation

The VECTOR-SIL solution executes a VECTOR autopilot software version with a simulator embedded.

Mission Planning

Train the operators in the use of UAV Navigation GCS tools in order to check flight plans or safety conditions.

3D Model view

A 3D Model may be included to setup a more realistic environment.

Simulate Weather Conditions

Simulate weather conditions such as wind.

The VECTOR-SIL solution executes a VECTOR autopilot software version that incorporates a simulator embedded into the autopilot code. The VECTOR-SIL allows customers to train their pilots with UAV Navigation’s system.

To provide a training environment to the user, the following capabilities are available: 

     Perform a simulated mission before the flight to check Flight plans and safety conditions.

●  Train operators in the use of UAV Navigation Ground Control Station tools: flight plan editor, flight modes, no-fly zones edition…

     The VECTOR-SIL may be used during deployments as it is a compact affordable unit.

     Plug and play configuration, no complex hardware or wiring are required.

●  The VECTOR-SIL allows customers to train their operators in multiple platforms: rotary wing, fixed-wing, target drone…

GCS software training tool


 Both simulation solutions allow the user to simulate a UAV operation with different fidelity levels. All guidance modes from Manual flight to a completely automatic simulation can be simulated allowing the UAV pilot  to rehearse missions or train in the use of the system.

Simulation fidelity

Logic Level Generic / Custom

The VECTOR-SIL solution executes a VECTOR autopilot  software version that incorporates a simulator embedded into the autopilot code. While this assures SIL will behave exactly like the real autopilot at the logic level,  execution times and sensor behavior are not the same as in real operation.

HIL on the other hand executes the exact same VECTOR code as the flight ready autopilot relying on an external CPU to create a  simulation environment mimics the expected  sensor and actuator delays. For control gain adjustment and advanced training, or platform modification testing HIL is the correct option.

Advanced and emergency procedure simulation



 Although the SIL can simulate most of operational situations, the HIL simulator includes some additional  scenarios such as advanced weather simulation (wind and random gusts) , advanced sensor and actuator failure simulation (from blocked servos to jammed or spoofed GNSS), taxi, more realistic depictions of runway take off and landing, catapult launch or engine telemetry  simulation. 

Physical Aircraft Model

Generic Custom VECTOR-HIL allows for complete customization of your aircraft. This includes: custom stability derivatives,  ground interaction parameters such as landing gear position, taxi simulation or distributed thrush among multiple engines.

FlightGear interface



 Through the use of Visionair’s “FLIGHT GEAR” tool it is possible to interact with flight gear with both the SIL and the HIL. However this feature represents autopilot telemetry which is constrained by data link bandwidth limitations. HIL simulator has a much faster refresh rate making flight gear visualization more compelling for client DEMO and showrooms. Also HIL ground interaction is integrated with Flight Gear ensuring the best simulation behavior.

Instructor Position

- VECTOR-HIL simulator enables an instructor to control the simulation while the operator student faces the operational awareness he would have during a real flight. In the VECTOR-SIL this setup is not possible.

Sea operations



 HIL simulation environment includes the possibility of simulating the operation of UAV from the deck  of a vessel. The simulation includes the control of the ship and its interaction with the sea waves.


- HIL simulator is open to platform specific customization of the simulation environment as it is run on a different HW. For example the number and position of the engines or variations in the mass center depending on fuel consumption or payload use.

Iron Bird Integration



VECTOR-HIL with its exposed GPIO and com ports hardware is designed to allow the integration into an “iron bird” testbed.
