Sparse coding cuts data burden for high-precision GNSS

Tracy Cozzens — Tue, 18 Aug 2026 23:25:43 +0000

A new compression framework could make high-precision GNSS atmospheric corrections easier to store, transmit, and use where ground networks are unavailable. The study introduces a training-free sparse representation method that reduces the data burden of global tropospheric grid models while preserving the accuracy needed to estimate zenith tropospheric delay (ZTD), a major source of positioning error. […]

NASA’s Starling Mission Opens New Frontiers in Space Navigation

Tracy Cozzens — Tue, 18 Aug 2026 22:33:26 +0000

NASA’s Starling mission has marked another milestone in spacecraft autonomy by using a new system that determines a satellite’s position in orbit by referencing other objects in space, instead of relying on a navigational network. The FALCON (Fast Autonomous Lost-in-space Catalog-based Optical Navigation) technology demonstration is a step toward spacecraft being able to operate more independently. As NASA prepares for more missions beyond Earth’s orbit, technologies like FALCON can support lunar satellite swarms, distributed science missions, and human exploration. Traditional satellite navigation […]

Ericsson, MediaTek achieve decimeter-level accuracy via 5G with 3GPP-based GNSS RTK

Tracy Cozzens — Tue, 18 Aug 2026 22:23:55 +0000

Test sets new standard for precise positioning on a commercial 5G network Ericsson and MediaTek have successfully completed an end-to-end test of high-precision outdoor positioning. Utilizing standardized 3GPP technology for GNSS real-time kinematic (RTK), the partners demonstrated positioning accuracy down to a ten-of-centimeters directly over a commercial 5G network. Traditional GNSS often has an accuracy of […]

Microchip launches radiation-tolerant atomic clock for LEO satellites

Tracy Cozzens — Tue, 18 Aug 2026 21:57:11 +0000

Microchip Technology has expanded its atomic clock portfolio with the radiation-tolerant Space CSAC-SA65, a chip-scale atomic clock designed to deliver precise timing for space systems. The device provides a compact, low-power alternative to traditional radiation-hardened timing solutions, helping developers reduce size, weight, power and cost while maintaining accuracy. Building on the heritage of Microchip’s Space CSAC-SA45, the […]
