Evaluation of BDS Navigation Signals and Positioning Performance on Android Devicests. At present, the research of Android devices positioning based on original observations mostly focuses on GPS/GLONASS/Galielo, and there is few in-depth evaluation work on the data observation quality and positioning performance of BDS. In general, compared with traditional survey-grade GNSS rece

Precise Point Positioning Performance Evaluation of QZSS Centimeter Level Augmentation Services includes satellite orbit correction, clock correction, phase bias, code bias, troposphere correction, ionosphere correction and other augmentation messages. These augmentation messages are used for a PPP-RTK service. Using PPP-RTK service, users in Japan can get high-precision real-time positionin

Performance Analysis of BDGIM to correct the single frequency ionospheric delay in BDS. As a new model, it is necessary to analyze the performance of BDGIM. Based on the ionosphere data of CODE, this paper compares the performance of BDGIM with that of BDSKlob, GPSKlob and NeQuickG in the aspects of space, time and the effects

Analysis of BDS-3 and BDS-2 Satellite Multipath Error BDS-3. There are three different orbit for BDS satellites including GEO, IGSO and MEO, and 4 open service signals including B1I, B2I, B3I, B1C and B2a. Compared with BDS-2, the on-board payload of the BDS-3 has been redesigned, and the parameters of signals are designed to be better, especially in

Assessing Android Smartphone Based GNSS Positioning Accuracyaster emergency response, public safety and other fields. In 2016, Google released the Android 7.0 operating system, low-cost mobile platforms began to support GNSS raw observation output, from then on, high precision positioning based on Android intelligent devices became possible. However, multi-p
