ALTM-GEN3 NAL Iridium ALTM Gen3, PNT

ALTM-GEN3 NAL Iridium ALTM Gen3, PNT

Alternative Location and Timing Module (ALTM) GEN3 is a powerful, small-form factor solution that delivers continuous access to Position, Navigation, and Timing (PNT) information. A low size, weight, and power (SWaP) device, ALTM GEN3 is ideal for dismounted, ground-vehicle, and airborne operations.

This embedded Iridium STL module utilizes a signal 1000x stronger than GPS, reliably providing accurate timing, location, and data when GPS fails, even indoors and in jammed/spoofed environments.

An inertial measurement unit (IMU) and tightly coupled Kalman filter (TCKF) enable enhanced performance in dynamic situations and can be bypassed if not needed.

ALTM GEN3 contains a satellite receiver, a UART for serial input of high-accuracy commercial or military GPS, a UART serial port for data I/O, an IMU, and a 1-PPS timing signal output.

For easy integration and robust operation, ALTM GEN3 uses one 40-pin Hirose connector with power and digital interfaces for PNT messages.

Key Benefits:
1) Typical static position accuracy < 25 m
2) Integrated IMU (Inertial Aided PNT) and Kalman filter
3) Choice of IS-GPS-153 or NMEA message format
4) External GNSS pass-through allows ALTM to be added to existing products
with GNSS without an additional UART
5) Approximately 1.5W power consumption and < 26 cm² (< 4.0 in²)
6) Timing accuracy

Key Features:

• Designed for high-mobility uses such as vehicles, aircraft and maritime
• On-board MEMS IMUs + external IMU and sensor inputs for a fused PNT solution
• Compact design enabling easy integration
• 4 square inches
