\n Pitch & Roll axes at the user's head level <\/h4>\n

Motion Aligned with Your Biological Accelerometers<\/b>

\n\nMost racing rigs on the market put pitch & roll axes under the seat.

While this may seem a practical engineering choice, it has a negative impact on the perceptual realism of the accelerations felt by the user. \n (This video<\/a> explains it well.)\n

\n\n\n\nGravideck simulators solve this by placing both pitch and roll axes at your head level<\/b>, bringing the center of rotation close to your vestibular system. The result: correct transient cues, clean coordination sensations, and racing & flight dynamics that feel coherent.

\n Racing experiences <\/h4>\n

The Gravideck Horizon dramatically enhances the racing experience through its unique motion architecture. By aligning transient and sustained accelerations, it reproduces centrifugal forces and rapid weight transfer with unprecedented realism. This results in far more convincing cornering sensations, complemented by powerful forward acceleration cues and immersive heave effects.<\/p>\n\n <\/div>\n <\/div>\n\n <\/div>\n\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

\n Flight Simulation <\/h4>\n

Flight simmers no longer have to adapt racing rigs. The Gravideck Horizon, with its 500\u202fmm stroke<\/b> actuators, excels for both racing and flight, delivering realistic vertical forces, pitch, and subtle roll cues. Those powerful actuators lets the system convey turbulence, longitudinal accelerations, and runway feel\u2014making it a perfect fit for immersive flying.<\/p>\n\n <\/div>\n <\/div>\n\n <\/div>\n\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

\n Flight Simulation becomes real <\/h4>\n

Flight simmers have long been forced to repurpose racing simulators for motion \u2014 until now. The Gravideck Horizon motion simulator has been optimized to work equally well for racing & flight<\/b>, offering an unparalleled, adrenaline-pumping flying experience.

\n\n\n\nThe importance of Heave for a good flight experience

<\/b>Heave motion is a crucial component in a flight motion simulator. When an aircraft pitches up or down, heave simulates the vertical forces generated by the change in trajectory\u2014similar in principle to how a car driver feels lateral forces when turning, but in the vertical direction. Heave also plays a key role in conveying turbulence, feel the texture of the runway and assess landing smoothness, offering haptic feedback that visual cues alone cannot provide.

\n\nPitch: the unsung hero of motion simulation<\/b>

\nPitch is a key component in motion simulation, serving not only to represent changes in the aircraft\u2019s attitude and angle of attack, but also as a surrogate for longitudinal accelerations. Hence, a sufficient pitch envelope is paramount for a great immersive experience.

\nRoll: the chef\u2019s kiss\u2026 when used correctly.<\/b>

Some motion simulator manufacturers love to showcase dramatic roll angles during aircraft turns. The problem is that this is physically inaccurate. In reality, during a coordinated turn, the pilot initially senses a small roll as the aircraft banks, but almost immediately, centrifugal (lateral) forces counteract this, effectively \u201cflattening\u201d the sensation. Overemphasizing roll in a simulator can therefore create unrealistic cues. In a properly tuned system like the Gravideck Horizon, the roll range is used sparingly in flight.<\/p>\n\n <\/div>\n <\/div>\n\n <\/div>\n\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
