ALTM Gemini 167

Product catalog summary

Introduction
The ALTM Gemini is the latest addition to the ALTM family, offering enhanced capabilities for base mapping. It maintains the performance of the ALTM 3100EA while allowing higher altitude operations at peak repetition rates, making it ideal for base mapping needs.

Key Features

Multipulse Technology: Allows operation at double the conventional altitudes without compromising data density compared to single-pulse systems.
Pulse Repetition Rate: Effective rate of 167 kHz, enhancing mapping efficiency.
Intensity Capture: Provides lidar imagery with a large dynamic range.

Specifications

Operational Altitudes: 150-4000 m AGL, nominal.
Horizontal Accuracy: 1/5,500 x altitude (m AGL); 1 s.
Elevation Accuracy: Less than 5–30 cm; 1 s.
Laser Classification: Class IV (US FDA 21 CFR).
Beam Divergence: Dual divergence of 0.25 mrad and 0.8 mrad, nominal.
Power Requirements: 28 V, 35 A (peak).
Operating Temperature: Control rack: +10° to +35°C; Sensor head: -10° to +35°C (with insulating jacket).
Storage Temperature: Control rack: -10°C to +50°C; Sensor head: 0°C to +50°C.
Humidity: 0-95% non-condensing.

Additional Features

Data Storage: Ruggedized removable SCSI hard disks.
Position and Orientation System: POS AV 510 OEM with embedded BD960 GNSS receiver (GPS and GLONASS).
Roll Compensation: ±5° at full FOV, more compensation available if FOV reduced.
Scan Frequency: 0 to 70 Hz, programmable in 1 Hz increments.
Scan FOV: 0-50°, programmable in ±1º increments.
Range Capture: Up to 4 range measurements, including 1st, 2nd, 3rd, and last returns.

Conclusion
The ALTM Gemini is a versatile and advanced lidar system, offering high-altitude operation and exceptional data quality, making it a suitable choice for comprehensive base mapping solutions.
