Furuno Electric and Xona Space Systems have signed a Memorandum of Understanding (MoU) to collaborate on solutions using Xona Pulsar, a low-Earth-orbit positioning, navigation and timing (LEO PNT) service for next-generation satellite navigation.
Through the agreement, both companies will leverage their respective technological expertise and business strengths to explore opportunities for delivering advanced and promising LEO PNT solutions.
Furuno has been actively pursuing LEO PNT as a promising technology capable of complementing or even substituting for GNSS.
LEO PNT refers to systems that use a satellite constellation of 200 to 400 satellites deployed in low Earth orbit at an altitude of 500 km to 2,000 km. The LEO constellation is designed for PNT rather than non-terrestrial networks to provide global positioning and timing services similar to GNSS, but with significantly better performance.
Xona is a pioneer in LEO PNT technology and offers a commercial service called Pulsar, which uses a dedicated LEO PNT constellation of 258 satellites. Compared to conventional GNSS, this service enhances resiliency and improves the accuracy of positioning and timing — the proximity of LEO satellites to Earth makes their signal power about 100 times stronger.
Pulsar adopts a signal architecture similar to GNSS for compatibility, making it easy to integrate into existing GNSS products. Integrating Xona Pulsar into Furuno’s products will provide an alternative to GNSS while significantly boosting performance by complementing existing GNSS services.
Furuno’s Pulsar-enabled timing solutions allow users to maintain accurate synchronization even when GNSS is degraded due to unexpected failures, including jamming and spoofing, the companies said.
