HELIDAS

Helicopter Integrated Digital Acquisition System


placeholder

Building on our successful MIDAS line of products, the HELIDAS efficiently captures sensor data from cameras, LiDAR systems, Infrared sensors, and other devices. Lead'Air's equipment is fully integrated with the Applanix line of INS systems, from AP15 to AP60 depending on the required accuracies for your application. In addition, we have complete integration with Riegl's Airborne LiDAR Systems. Lead'Air owns and operates our own Bell 206B helicopter and two Piper Seneca's with 25" camera ports so we can fly and test our products in flight on a real project. The system is particularly adapted to low-level flight, automatically tracking and firing at very low altitudes, and delivering very fine GSD better than 0.25 inch (0.6cm).

Features


Real-Time Targeting

Controlling the fully stabilized platform, the system can automatically follow a predetermined path or manually target the system using the joystick and real-time feedback from the video camera to the Blackmagic Video Assist display and capture system. The system can optionally maintain a manually targeted position based on IMU data as well as auto-correct for horizon changes. The HELIDAS IMU compensating helicopter mount allows for ±25° roll, ±15° pitch and ±45° yaw. These extreme angles allow for full stabilization of the aircraft tracking the fight lines, greatly enhancing productivity and assuring orthogonal image geometry

Equipment Testing in Actual Conditions

Distinguishing ourselves as one of the only companies in this industry to own their own Helicopter (Bell 206B Jet Ranger) and fixed wing aircraft, Lead’Air has the ability to test every system we create in actual flight conditions. One of our first helicopter test flights of a HELIDAS is shown below. Testing every piece of equipment we have created for our clients is our way of assuring the quality and durability of our products meets our own rigorous standards before it reaches our customers hands.

Powerful control center

The HELIDAS is controlled by a MIDAS Computer Control Center and takes advantage of the years of development that went into creating the world renown Oblique Imaging System, the MIDAS. The MIDAS Computer Control Center contains: all the necessary controls for each camera, IMU, Navigation interface, stabilized mount and all power functionality for the system.
