“…From a previous study, there are many mitigation techniques used to reduce the pseudorange multipath error. These techniques can be divided into three categories: antenna design (Groves et al, 2013), receiver-based correlator design (Matera el al., 2019;Sánchez et al, 2017), and post-processing technique (Hsu et al, 2016;Iwase et al, 2013;Lin et al, 2018;Matera et al, 2019;Sánchez et al, 2017;Špánik and Hefty, 2017;Suzuki, 2011;Suzuki and Kubo, 2015;Satirapod and Rizos, 2005;Dammalage et al, 2010). Without involving modification of the antenna used or the complexity of implementing the receiver's architecture, the post-processing technique is the optimum choice for work that does not require a high-precision solution.…”

“…Intensive research efforts have been expanded to enhance GNSS precise positioning in harsh environments. The two mostly investigated directions are multi-sensor fusion [4,5,6] and robust GNSS positioning algorithms [7,8], respectively. Firstly, by integrating GNSS with self-contained sensors such as inertial navigation systems (INS), unmanned vehicles are able to maintain accurate navigation through GNSS signal outages for a short time, which is normally one minute or more [9].…”

“…Nevertheless, the challenge in GNSS/INS integrated positioning comes with its disability for long-term precise navigation during GNSS blockages due to the significant bias drift in consumer-grade INS modules, which are usually applied in commercial unmanned vehicles. Secondly, existing algorithms to improve the robustness of GNSS positioning against degraded environments mainly focus on the elimination of noisy GNSS measurements and anomalies, such as multipath detection algorithms [7] and Carrier phase-based Receiver Autonomous Integrity Monitoring (CRAIM) [8]. That is, the robustness and precision gains come at the cost of reduced availability.…”
