The second generation of the Alternative Location and Timing Module (ALTM GEN2) is a standardized, small form factor, AltNav receiver that provides Position / Location Information (PLI) and timing, independent of GPS. The ALTM GEN2 is designed to be employed during dismounted, ground-vehicle, and airborne operations. It is capable of tracking personnel, vehicles, and assets.

The ALTM GEN2 leverages a combination of an AltNav receiver, a UART serial port input for high-accuracy GPS, and a UART serial port for data I/O, and a 1 PPS timing signal. For robust operation and ease of integration the ALTM GEN2 receiver has two 40-pin Hirose connectors with power and digital interfaces for PLI signals.

The ALTM GEN2 was designed to be a drop-in replacement for the ALTM GEN1, providing the user with all the AltNav capabilities of the GEN1, as well as containing receiver improvements, power optimization and decision logic.
