News Summary:

On October 1, 2026, Oscilloquartz expanded its collaboration with Iridium Communications, adding support for Iridium positioning, navigation, and timing (PNT) services to more products in its synchronization portfolio. This allows users of additional Oscilloquartz platforms, including ruggedSync, edgeSync PTP grandmasters, NTP servers, accessSync miniature PTP grandmasters, and OSAinside embedded synchronization solutions, to access Iridium’s satellite-based timing, positioning, and navigation services as an alternative source of timing and location information when Global Navigation Satellite System (GNSS) signals are unavailable or disrupted. Oscilloquartz, an authorized reseller and Adtran's assured PNT subsidiary, enables customers to purchase both Iridium PNT service subscriptions and the synchronization solutions that leverage them through a single supplier. Previously, on August 19, 2026, Oscilloquartz expanded its US aerospace defense and government presence, responding to a rising demand for resilient PNT solutions amid increasing GNSS cyber threats. This expansion included agreements with six specialized sales representative firms: ProTEQ Solutions, Southern Marketing Associates (SMA), Testech, TMS Sales, Contech Marketing Associates, and Ward/Davis Associates.
