GPS often struggles in cities because skyscrapers reflect and block satellite signals, leading to inaccurate locations. A new system called SmartNav tackles the problem with advanced corrections and ...

The SparkFun RTK EVK is the perfect development platform for your fixed or mobile high-precision positioning and navigation needs. We called it the EVK (Evaluation Kit) as it truly covers all the ...

Precision is designed, not accidental. Warehouse robots and drones require centimetre-level accuracy beyond the capability of standard global navigation satellite systems. Achieving this requires the ...

A new GNSS module enables global centimetre-level positioning without heavy ground infrastructure, combining multi-band satellite signals and cloud-based corrections for robotics, drones, agriculture, ...

What is the most striking detail of your system? The F200 is a retrofit autosteer system with an electric steering wheel motor, GNSS receiver (multi-constellation, control terminal (10.1”) and angle ...

Our everyday GPS struggles in “urban canyons,” where skyscrapers bounce satellite signals, confusing even advanced navigation systems. NTNU scientists created SmartNav, combining satellite corrections ...

Strong GPS signals are required to navigate with electronic maps while driving in the city. For driverless cars, this is especially important. Now, researchers have figured out how to make GPS ...

Abstract: The global navigation satellite system (GNSS) network-based real-time kinematic precise point positioning (PPP-RTK) technique, which integrates the advantages of PPP and RTK, has been ...

CSSRlib is a open toolkit in Python for high accuracy GNSS positioning. It supports SSR (State-Space Representation) based positioning for PPP (Precise Point Positioning) or PPP-RTK (Realtime ...

Precise Point Positioning (PPP) has long held promise as a standalone, high-accuracy positioning technique, but its slow convergence and complexity in ambiguity resolution have limited widespread use.
