• AIMS CHARACTERISTICS
• Fully Digital Airborne Data Acquisition System
• Direct Platform Orientation by Tightly Coupled
  GPS/INS
• Typical fit to ground truth
• 2-20 cm for flight altitude 300m
• 0.2-3 cm for land-based applications, 10-20 m
• object distance

• IMPORTANT ISSUES
• Boresight Alignment
• Multi-sensor Calibration
• Time Synchronization
• Rigid Mount
• Continuity of GPS Lock

Error growth during GPS outage
