Modifying the stochastic model to mitigate GPS systematic errors in relative positioning
(2007-12-01)
The GPS observables are subject to several errors. Among them, the systematic ones have great impact, because they degrade the accuracy of the accomplished positioning. These errors are those related, mainly, to GPS ...
An effective wavelet method to detect and mitigate low-frequency multipath effects
(2008-12-01)
To ensure high accuracy results from GPS relative positioning, the multipath effects have to be mitigated. Although the careful selection of antenna site and the use of especial antennas and receivers can minimize multipath, ...

Low-cost system for on-board image processing in real time, applied to disaster mitigation
(American Institute of PhysicsPE, 2023-04-04)
The climate change that affects our planet is constantly causing natural disasters, due to the increase in temperature, development of extreme rains, causing rivers to overflow; Thus, natural phenomena such as earthquakes ...

The impact of adding SBAS data on GPS data processing in southeast of Brazil: Preliminary result
(2012-12-01)
Nowadays, L1 SBAS signals can be used in a combined GPS+SBAS data processing. However, such situation restricts the studies over short baselines. Besides of increasing the satellite availability, SBAS satellites orbit ...
