Benefit of triple-frequency on cycle-slip detection [PDF]
, 2018 At the time of writing, all the Global Navigation Satellite Systems (GNSS) support or are designed to support triple- or multi- frequency, which is expected to have advantages over single- and dual- frequency.

Space Weather and Low‐Altitude Drone Economy
Space Weather, Volume 24, Issue 1, January 2026.Abstract Unmanned Aerial Vehicles (UAVs) are becoming integral to the emerging low‐altitude economy, operating primarily below 3,000 m for applications such as logistics, inspection, precision agriculture, and urban air mobility. The safe and reliable operation of UAVs depends critically on communication, navigation, and surveillance (CNS) systems ...

InSAR Ground Deformation and Pumping Energy Consumption Reveal Urban Water Security
Water Resources Research, Volume 62, Issue 1, January 2026.Abstract Water resource assessments are critical for ensuring water security (WS), particularly in rapidly urbanizing regions with increasing water demand and limited water monitoring capabilities. Earth observations and indirect indicators of surface and groundwater changes are valuable tools for developing such assessments.

Multi-GNSS Precise Point Positioning with Ambiguity Resolution Based on the Decoupled Clock Model
Remote SensingAmbiguity resolution (AR) can markedly enhance the precision of precise point positioning (PPP) and accelerate the convergence process. The decoupled clock model represents a pivotal approach for ambiguity resolution, yet current research on this topic ...

Research on a Dual‐Mode Human–Robot Interaction Method Based on a Large Language Model
IET Cyber-Systems and Robotics, Volume 8, Issue 1, January/December 2026.ABSTRACT Current guide robot systems have two main issues: (1) they only support a single mode of interaction (proactive or reactive) and lack a coordination mechanism and (2) they rely heavily on predefined content, which hinders the realisation of a natural and flexible human‐like interaction experience. To address these issues, this paper proposes a
