TLDR
In this paper, the authors analyzed the influence of geomagnetic storms on the satellite navigation system, especially the Beidou satellite navigation systems, taking a strongly storm which took place from March 9th, 2015 to March 21st as an example, respectively, analyzing BDS and GPS ionospheric delay precision when ionosphere is quiet or disturbed.Abstract:
Geomagnetic storm activity will cause a certain degree of disturbance on the global ionosphere; ionospheric model error which is one of the main error sources of satellite navigation system will affect the service performance of the satellite navigation system In order to analyze the influence of geomagnetic storms on the satellite navigation system, especially the Beidou satellite navigation system, this paper takes a strongly storm which took place from March 9th, 2015 to March 21st as an example, respectively, analyze BDS and GPS ionospheric delay precision when ionosphere is quiet or disturbed Further, it makes contrast the difference of positioning accuracy between BDS and GPS when ionopheric disturbance happened in March, 2015 The results show that BDS and GPS ionopheric model are affected by the storm, both the ionopheric model correction rate and service performance are decreasedread more

A New Ionospheric Model for Single Frequency GNSS User Applications Using Klobuchar Model Driven by Auto Regressive Moving Average (SAKARMA) Method Over Indian Region
TL;DR: The experimental results of SAKARMA for NavIC have revealed that the MAPE for proposed SAKarMA model is 9-17% (accuracy: 83-91%), while 34-53% (Accuracy: 47-66%) for the Klobuchar model, illustrating that the proposed SakARMAmodel is capable of predicting the ionospheric delays for single frequency GNSS/NavIC users.

Evaluation of COMPASS ionospheric model in GNSS positioning
TL;DR: Results show that in the Northern Hemisphere areas including Asia, Europe and North America, the three-dimensional positioning accuracy using the CIM for ionospheric delay corrections is improved, and the positioning accuracy in the Southern Hemisphere is degraded due apparently to the lack of monitoring stations there.
