Atmospheric Effects on RTK Network in Florida

Abstract

Commonly used real time kinematic (RTK) network (RTK Network) techniques, i.e., MAX, I-MAX, FKP and VRS, are tested by taking monthly measurements for a year in Florida. Additionally, RTCM message versions 2 and 3 are used with I-MAX and VRS measurements. The results revealed that mostly, horizontal coordinates vary a few centimeters and generally changes in vertical coordinates are less than two decimeters. In terms of horizontal coordinates, the best results are produced by I-MAX3 method and FKP yielded the worst results. In terms of vertical coordinates, almost all results look alike; however, the best results are produced by VRS3 method. It appears that I-MAX3 performed better than I-MAX2 and VRS3 performed better than VRS2. Yet, MAX did not stand out among other techniques.

Generation and Performance Analysis of GPS and Glonass Virtual Data for Positioning Under Different Ionospheric Conditions

“…In recent years, several methods were developed aiming to verify the quality of data from the VRS concept. Some positioning methods were applied in this context, considering relative positioning (Alves, Monico and Dalbelo 2007;Alves and Monico 2010;2011;Alves, Abreu and Souza 2013), RTK (Silva, Monico and Alves 2016;Berber and Arslan 2015) and precise point positioning (Alves, Monico and Dalbelo 2009;Alves and Monico 2011;Alves et al 2016;Oliveira, Alves and Ferreira 2014a). In addition, some studies investigated the use of some atmospheric models, as in Alves, Monico and Dalbelo (2007), Alves et al (2016) and Oliveira, Alves and Ferreira (2014a;2014b).…”
