GVX aims to provide a standard file format for exchanging GNSS vectors derived from varying GNSS survey methods and manufacturer hardware. The file format includes all of the necessary data of a GNSS vector for inclusion in a survey network for least squares adjustment, as well as crucial metadata.

Feb 11, 2025 · GNSS Vector Exchange Format (GVX) is designed by NOAA/NGS, aiming to provide a standard format for exchanging GNSS vectors derived from varying GNSS survey methods and manufacturer hardware.

VectorNav’s GNSS/INS (GNSS-Aided Inertial Navigation System) products feature the industry’s leading INS algorithms, delivering performance well beyond what products of its size and weight commonly deliver, even in the most challenging dynamic conditions.

A GNSS vector is sometimes referred to as a “baseline solution” because it is a mathematical representation of the post-processing and differencing of the raw GNSS data collected at the receivers.

Detailed information of each GNSS vector is shown in the table below the map, including: Repeat vectors between the same two marks, organized into “To” - “From” baselines; Vector ID as stated in the uploaded GVX file or assigned by OP; GVX vector’s antenna type and height at the terminal point or “To” station.

Jan 13, 2021 · The GEM Strain Rate Map Project compiles velocity data from thousands of GPS/GNSS stations around the world, and models plate motions and crustal strain.

The RTK vector information is available only when the receiver is receiving RTK corrections from a static or moving RTK base. Select Receiver Status / Vector . Vector – The RTK vector between the base and rover antennas.

Sep 4, 2019 · The National Geodetic Survey (NGS) is requesting input and feedback on a new data format for sharing real-time kinematic (RTK) GNSS vector information. The new format will be like the static GNSS standard, Receiver Independent Exchange (RINEX), and is utilized by most software packages and the Online Positioning User System (OPUS).

GNSS scalar tracking loop tracks each satellite signal in one channel separately, while vector tracking loop track all of the satellite signals in one navigation filter. Three major advantages of the vector tracking loop are reduction of estimated parameters, aiding weak signal tracking by strong signal and aiding signal tracking by navigation ...

Apr 25, 2009 · Vector-based tracking loops combine the two tasks of signal tracking and position/velocity estimation into one algorithm. In contrast, traditional — or scalar — tracking methods track each satellite’s signal (s) independently; both of each other and of the position/velocity solution. Vector tracking has many advantages over scalar tracking loops.
