NAL Technologies unveils ALTM-T timing module for resilient APNT applications

MANASSAS, Va. - NAL Technologies has introduced the ALTM-T, a new embeddable Alternative Location and Timing Module designed to provide resilient precision timing and synchronization for critical infrastructure and other applications vulnerable to GNSS and GPS signal disruptions.

The ALTM-T module is optimized for precision timing applications requiring redundancy alongside other assured positioning, navigation, and timing, or APNT, sources. The company says the receiver delivers timing accuracy of less than 50 nanoseconds RMS while conforming to the compact M.2 3042 B-key form factor and consuming less than 600 milliwatts of power.

The module is intended for size-, weight-, and power-constrained systems supporting infrastructure such as electric power grids, financial networks, transportation systems, and data centers that rely heavily on accurate timing and synchronization data for operational continuity and transaction integrity.

NAL Technologies officials say the increasing complexity and interconnectivity of modern infrastructure have heightened concern over cyberattacks, jamming, spoofing, and other threats affecting GNSS and GPS signals.

Rob Gillette, APNT solutions director at NAL Technologies in Manassas, Va., said APNT technology is intended to complement GNSS and GPS systems by providing additional resilient timing sources capable of maintaining synchronization during signal disruptions.

The ALTM-T receiver uses the Iridium positioning, navigation, and timing signal as a complementary APNT source. The company says the Iridium-based signal is significantly stronger than conventional GNSS and GPS signals and can penetrate indoor environments while mitigating intentional and unintentional interference.

NAL Technologies says it has deployed more than 13,000 Iridium PNT-enabled receivers since introducing its first ALTM product in 2019.
