Impact and mitigation of space weather effects on GNSS receiver performance (2016)
Journal Article
Sreeja, V. (2016). Impact and mitigation of space weather effects on GNSS receiver performance. Geoscience Letters, 3(1), 1-13. https://doi.org/10.1186/s40562-016-0057-0

It is well known that Global Navigation Satellite System (GNSS) signals suffer from a number of vulnerabilities, out of which a potential severe vulnerability is the effect of space weather. Space weather effects on the signals transmitted by GNSS in... Read More about Impact and mitigation of space weather effects on GNSS receiver performance.

Performance of ionospheric maps in support of long baseline GNSS kinematic positioning at low latitudes (2016)
Journal Article
Park, J., Sreeja, V., Aquino, M., Cesaroni, C., Spogli, L., Dodson, A., & De Franceschi, G. (2016). Performance of ionospheric maps in support of long baseline GNSS kinematic positioning at low latitudes. Radio Science, 51(5), 429-442. https://doi.org/10.1002/2015RS005933

Ionospheric scintillation occurs mainly at high and low latitude regions of the Earth and may impose serious degradation on GNSS (Global Navigation Satellite System) functionality. The Brazilian territory sits on one of the most affected areas of the... Read More about Performance of ionospheric maps in support of long baseline GNSS kinematic positioning at low latitudes.
