Special Issue Information

Dear Colleagues,

GNSS has been acting as a fundamental infrastructure for the sounding of the ionosphere and troposphere for decades. With ground- and satellite-based GNSS observation techniques, ionosphere and troposphere models and products are derived and produced at different temporal and spatial scales with good accuracies. This in turn facilitates the research and application of GNSS precise positioning and navigation by providing accurate a priori information on atmospheric delays. Moreover, recent developments in the GNSS community highlight the deployment of low-earth-orbit satellite constellations for navigation augmentation, which will further bring about new thoughts and methodologies on using combined GNSS/LEO observations for enhanced remote sensing.

In this regard, we are pleased to announce the launch of a new Special Issue of Remote Sensing, entitled “GNSS Positioning and Navigation in Remote Sensing Applications”. The goal of this Special Issue is to collect new algorithms, methods, and results on ionosphere and troposphere retrieval and production based on GNSS observations, as well as their applications in GNSS precise positioning and navigation. Research topics include, but are not limited to, the following: (a) ionosphere/troposphere retrieval and modeling based on GNSS; (b) GNSS precise positioning assisted by ionosphere and troposphere models and products; and (c) combined GNSS and LEO for ionosphere and troposphere sounding. Papers focusing on the following aspects are especially welcome:

  • GNSS precise positioning: methods and algorithms;
  • LEO-enhanced GNSS positioning and navigation;
  • Ionosphere modeling with GNSS;
  • GNSS troposphere sounding and modeling;
  • LEO-enhanced GNSS remote sensing.

The BeiDou Navigation Satellite System (BDS) has developed rapidly, and the combination of BDS Phase II (BDS-2) and BDS Phase III (BDS-3) has attracted wide attention. It is found that there are code ISBs between BDS-2 and BDS-3, which may have a certain impact on the BDS-2 and BDS-3 combined positioning. This paper focuses on the performance of BDS-2/BDS-3 combined B1I single-frequency pseudorange positioning and investigates the positioning performance with and without code ISBs correction for different types of receivers, include geodetic GNSS receivers and low-cost receivers. The results show the following: (1) For geodetic GNSS receivers, the code ISBs of each receiver is about −0.3 m to −0.8 m, and the position deviation is reduced by 7% after correcting code ISBs. The code ISBs in the baseline with homogeneous receivers has a little influence on the positioning result, which can be ignored. The code ISBs in the baseline with heterogeneous receivers is about −0.5 m, and the position deviation is reduced by 4% after correcting code ISBs. (2) The code ISBs in the low-cost receivers are significantly larger than those in the geodetic GNSS receivers, and the impact on the positioning performance of the low-cost receivers is significantly greater than that on the geodetic GNSS receivers. After correcting the code ISBs, the position deviation of low-cost receivers can be reduced by around 12% for both undifferenced and differenced modes. (3) For low-cost receivers, correcting the code ISBs can increase the number of epochs successfully solved, which effectively improves the low-cost navigation and positioning performance. (4) The carrier-phase-smoothing method can effectively reduce the distribution dispersion of code ISBs and make the estimation of ISBs more accurate. The STD values of estimated code ISBs in geodetic GNSS receivers are reduced by about 40% after carrier-phase smoothing, while the corresponding values are reduced by about 7% in low-cost receivers due to their poor carrier-phase observation quality.
