ALL.SPACE has been awarded €950,000 by the European Space Agency’s Navigation Innovation and Support Program (NAVISP)—this award is to develop an alternative Position, Navigation and Timing (PNT) capability designed to operate in Global Navigation Satellite System (GNSS)-denied environments. The project ...

Galileo relies on ground-based uplink stations (ULS) to maintain accurate positioning for users worldwide—these stations transmit essential data to the satellites, including the information required to compute the satellites' orbits and clock corrections. Traditionally, such messages are sent using dish ...

Roughly 12,550 miles above Earth, a constellation of U.S. global positioning satellites orbits the planet. GPS satellites also carry a sophisticated system designed to detect above ground nuclear detonations anytime, anywhere. The Global Burst Detection system, developed by Sandia and ...

QinetiQ and Xona Space Systems have demonstrated how GPS navigation can be bolstered by using LEO satellites during the first UK tests of Xona’s new satellite navigation system, Pulsar. This marks a major milestone in the development of next generation ...

Aerospace and defense applications rely on Position, Navigation and Timing (PNT) technology for mission-critical accuracy and reliability—however, integrating PNT into a design requires extensive domain knowledge in this area. To fast track the development process, Microchip Technology (Nasdaq: MCHP) has ...

Astroscale Ltd. (“Astroscale UK”), the UK subsidiary of Astroscale Holdings Inc., has agreed to provide Xona Space Systems with next-generation docking plates for integration into Xona’s growing constellation of LEO satellites.
