Xona Space Systems has received an oversubscribed $19 million Series A funding round to accelerate the development of its low Earth orbit (LEO) satellite navigation service.

The funding will be used to begin beta operations of the PULSARTM satellite service, with Aerospacelab playing a key role in the design, manufacturing, and launch of a navigation satellite equipped with Xona’s PNT payload.

The round was led by Future Ventures and Seraphim Space.
