Signature of ionospheric irregularities under different geophysical conditions on SBAS performance in the western African low-latitude region [PDF]
Rate of change of TEC (ROT) and its index (ROTI) are considered a good proxy to characterize the occurrence of ionospheric plasma irregularities like those observed after sunset at low latitudes.

AATR an ionospheric activity indicator specifically based on GNSS measurements [PDF]
This work reviews an ionospheric activity indicator useful for identifying disturbed periods affecting the performance of Global Navigation Satellite System (GNSS). This index is based in the Along Arc TEC Rate (AATR) and can be easily computed from dual-

Authentication of Satellite-Based Augmentation Systems with Over-the-Air Rekeying Schemes
Here we delineate a complete satellite-based augmentation system (SBAS) authentication scheme, including over-the-air rekeying (OTAR), that uses the elliptic curve digital signature algorithm (ECDSA) and timed efficient stream loss-tolerant ...
