    NAL Technologies unveils ALTM-T optimized for precision timing

    NAL Technologies (Naltec), a provider of assured positioning, navigationand timing (APNT) solutions, has added to its Alternative Location and Timing Module (ALTM) family with ALTM-T. The ALTM-T module is engineered for applications and infrastructure demanding precise location, timing and synchronization redundancy with other APNT sources.

    Critical network infrastructure — power grids, financial markets, transportation, data and centers — are heavily reliant on GNSS/GPS signals where precise timestamps, synchronization and transaction integrity, and operational continuity are key.

    ALTM-T is an ultra-low size, weight and power (SWaP) receiver ptimized for precision timing at <50ns RMS. It also conforms to the M.2 3042 B-key standard form factor and uses less than 600MW consumption, making it suitable for SWaP-constrained systems.

    “APNT technology complements GNSS/GPS, which is the invisible backbone of modern infrastructure,” said APNT Solutions Director, Rob Gillette, NAL Technologies. “Without additional timing sources such as APNT by Naltec, a failure of GNSS/GPS can trigger consequences that could cascade rapidly across utilities, transportation and financial markets. With ALTM-T, users will benefit from enhanced performance delivered from APNT by Naltec, to ensure resilient precision timing synchronization.”

    The embeddable ALTM-T receiver leverages the Iridium PNT signal to provide a complementary APNT source that is approximately 1,000 times stronger than GNSS/GPS. The APNT signal can penetrate indoor environments as well as mitigate intentional and unintentional GNSS interference for ultimate reliability.

    Naltec provider of Iridium PNT-enabled modules, with more than 13,000 receivers deployed since its first ALTM launch in 2019. ALTM-T is commercially available and now shipping.

    Iridium unveils global GPS device protection on a chip

    Iridium Communications Inc. has unveiled a dedicated, miniature application-specific integrated circuit (ASIC), the Iridium PNT ASIC. Engineered for seamless integration into a wide range of electronic devices, the Iridium PNT ASIC will deliver authenticated, pole-to-pole positioning, navigation and timing (PNT) data. It will provide a resilient alternative to traditional GNSS, offering protection against spoofing and jamming for consumer, industrial and government applications.

    The Iridium PNT ASIC measures 8 x 8 mm and can be fit into devices ranging in size from consumer products to major infrastructure systems like power grids, transportation systems and telecom networks. When embedded in a device, the Iridium PNT ASIC receives a cryptographically secure time and location data signal from the Iridium satellite network that is 1,000 times more powerful than GPS and capable of working inside buildings. This can help GNSS-dependent applications to not only detect a problem but also maintain operations until it is resolved. The Iridium PNT ASIC will also continuously verify signal integrity, making it a suiitable alternative or primary source of PNT data.

    Iridium showcased the ASIC’s capabilities during September’s Jammertest, an annual event that evaluates the resilience of GNSS and alternative PNT technologies under jamming and spoofing attacks. The Iridium PNT ASIC maintained both timing accuracy and reliable navigation during controlled exercises.

    Iridium is inviting organizations to apply to participate in beta trials, and, if selected, they will receive Iridium PNT ASIC evaluation kits, enabling early integration and testing. The Iridium PNT ASIC is planned for commercial availability in mid-2026.

    Iridium is highlighting the Iridium PNT ASIC at the International Timing and Sync Forum (ITSF) Oct. 27-30 in Prague.
