Orolia has synchronized a Spectracom SecureSync high-precision time server with the new Iridium Satelles Satellite Time & Location (STL) time synchronization signal powered by Iridium satellites in several indoor environments in the field. Configured with an embedded STL receiver and a small patch antenna, the SecureSync synchronized with the STL signal in several challenging indoor locations. Indoor success can be attributed in part to use of a low-Earth orbit satellite-based signal 1,000 times stronger than GPS. The first successful synchronization was in the interior of a building in one of the most challenging urban canyons on Earth: downtown Manhattan on the 7th floor of the New York Stock Exchange. The second was in the interior of a conference center with multiple sources of potential signal interference during The Institute of Navigation event in Monterey, California. Additional successful indoor timing signal synchronization locations include MiFiD2 events near the Paris Stock Exchange, a multi-story building and inside Gibson Hall in downtown London. More GNSS challenged locations to come, the two companies promise. Other satellite signals — notably GNSS — have limitations indoors. The Satelles STL signal uses the narrow-band paging channels of Iridium, a one-way transmission from the satellite with a very high gain system. The STL signal is completely different from the wide band, lower gain two-way channel of the Iridium phone. The STL signal is 1,000 times stronger than GPS because it originates from the Iridium constellation of 66 satellites orbiting in a low earth orbit. It is also encrypted for high security, which greatly enhances the resilient PNT capabilities of the Spectracom product lines, specificallly the SecureSync precision time and frequency reference. SecureSync with integrated STL synchronization is available to order from the Spectracom website or by contacting a representative. “The new STL signal is the ideal solution for those needing increased security and reliability, applications such as high frequency securities trading, financial transaction time-stamping compliance and critical infrastructure timing,” said John Fischer, vice president of Orolia for advanced R&D. “It is not only an additional signal to back up traditional GNSS, it is also stronger and more secure, adding significantly to the resiliency of high performance systems and networks that must rely on precise time synchronization.” Having proven the ability to provide a strong and reliable alternative signal in various indoor field locations, the new globally accessible STL signal adds a significant safety net to any critical GNSS application. Adding to the mix of signals of opportunity the resiliency of positioning and timing for financial, defense and critical infrastructure is greatly enhanced. “Orolia is focused on providing Resilient PNT solutions, and by combining and layering technology in innovative ways we help our customers meet their mission goals,” said Rohit Braggs, vice president of Orolia’s PNT networks and sources. “This new satellite-based service provides a unique signal that augments Spectracom systems, enhancing our ability to effectively mitigate emerging GPS and GNSS threats.” Orolia is the parent company of Spectracom, McMurdo, Kannad, and Sarbe brands, focused on resilient positioning, navigation and timing (RPNT) solutions that improve the reliability, performance and safety of customers’ critical, remote or high-risk operations. Satelles has developed and deployed a real-time PNT service based on low-Earth orbit satellites, the Iridium constellation. Satellite Time and Location (STL) signals are highly secure, penetrate deep indoors, and are available anywhere on Earth. Satelles partners with other companies to deliver secure time and location capabilities to government and commercial users worldwide.
