System Architecture for Server-Based Network-RTK using Multiple GNSS
Improved accuracy and reliability of the real-time user coordinates is expected if GNSS data is processed using the network-RTK technique. Some implementations of conventional network-RTK, e.g. Virtual Reference Station (VRS) techniques, require bi-directional communications via GSM/GPRS since the network server transmits network-corrections to a user, while the user receiver is required to tra...
متن کاملAtmosphere Decomposition for VRS-Based Network-RTK System
The atmospheric delay is the main error source for medium-range relative GPS positioning, and therefore is the main challenge for Network-RTK systems. The double-differenced tropospheric and ionospheric delays are decomposed from the double differenced ionosphere-free and geometry-free combinations. However, for a Network-RTK system, the atmospheric delays are required to be expressed as single...
متن کاملStereoscopic First Person View System for Drone Navigation
Ground control of unmanned aerial vehicles (UAV) is a key to the advancement of this technology for commercial purposes. The need for reliable ground control arises in scenarios where human intervention is necessary, e.g. handover situations when autonomous systems fail. Manual flights are also needed for collecting diverse datasets to train deep neural network-based control systems. This axiom...
متن کاملIonospheric Effects on Network-RTK
Ionospheric Effects on Network-RTK A part of the atmosphere is ionized by the UV radiation from the Sun. This part is often referred to as the ionosphere. The resulting free electrons influence the GNSS signals as they propagate through the ionosphere. We have studied how the spatial variations of electron density in the ionosphere affect measurements with network-RTK. The aim is to predict wha...
متن کاملNetwork-based RTK Positioning Using Integrated GPS and GLONASS Observations
With the recent rapid revival of the GLONASS constellation, it is possible for the GLONASS system to provide Full Operational Capability (FOC) service before the end of 2011. CDMA signals are now additionally modulated onto the first GLONASS-K satellite which was launched on February 26, 2011. It is envisaged that GNSS users will benefit from more visible satellites, better precision and higher...
