AIs LiDAR Specification

Litemapper

     The LiteMapper is a revolutionary LiDAR system for airborne LiDAR mapping and the world`s first available commercial system to feature high-resolution waveform digitization and recording. Its offers the opportunity of a detailed view into the vertical structure of the surface to the user.

     Airborne LiDAR Terrain Mapping System for 3D topographic surveys and 3D corridor mapping using fixed-wing aircrafts or helicopters. integration with the CCNS (Computer Controlled Navigation System- 4th generation),  LiDAR data are directly Geo-referenced through the AEROcontrol/DGPS/IMU based system that continuously registers sensor position and attitude in flight litemapper laser scanner sample the surface in parallel lines with regular point spacing both in and across flight direction to provide the most accurate surface representation.

     The scan speed can be varied in a range to provide very dense point spacing within each scan. the continuously rotating scanner used for beam deflexion is resistant to temperature variations and accelerations which typically occur under airborne operating conditions LiDAR terrain mapping with the litemapper system is a highly efficient method to rapidly acquire 3D terrain and surface data with accuracy. the laser beam directly measures the 3D coordinates of up to 200.000 surface point per second. LiteMapper is a complete solution to create a DTM and a DSM Data.

AeroControl

AEROcontrol is fully integrated with GPS and IMU for the precise determination of position and attitude of an airborne sensor. This can be the position of the projection center and the angles omega, phi, kappa of the aerial camera system or an airborne laser scanner. The system approximately records 18MB (128Hz) or 33MB (256Hz) of data per hour giving a maximum mission time of at least 15 hours with available 512MB PC-Cards. Depending on GPS constellation and distance from GPS Base/Monitor Station, a positioning accuracy better than 0.1m RMS and attitude accuracy of 0.01 deg RMS for heading and of 0.004 deg RMS for roll and pitch is available in post-processing. This accuracy is sufficient for direct georeferencing for many tasks. For large scale photogrammetric projects where a higher accuracy is required, the use of AEROcontrol results as additional information for an aerial triangulation (Integrated Sensor Orientation) leads to large savings in GCPs and processing time.
