Enhanced SBAS Integration Method Using Combination of Multiple SBAS Corrections

Real-Time Single Frequency Precise Point Positioning Using SBAS Corrections

Real-time single frequency precise point positioning (PPP) is a promising technique for high-precision navigation with sub-meter or even centimeter-level accuracy because of its convenience and low cost. The navigation performance of single frequency PPP heavily depends on the real-time availability and quality of correction products for satellite orbits and satellite clocks. Satellite-based au...

SBAS Presidential Address: Change Management, Leadership & the Society of Black Academic Surgeons (SBAS).

http://dx.doi.org/10.1016/j.amjsurg.2017.02.013 0002-9610/© 2017 Elsevier Inc. All rights reserved. Society of Black Academic Surgeons' members and guest, it has been a personal honor and a privilege to serve as the 21st president for The Society of Black Academic Surgeons (SBAS). I became a member of SBAS in 1997 and never dreamed of becoming its president; as my name joins the pantheon of ext...

L1/L5 SBAS MOPS to Support Multiple Constellations

This paper proposes a message structure for the L5 GEO data signal that can support more than 90 simultaneous L1/L5 satellite corrections. The proposal is similar to the existing L1 structure with 250 bit messages sent at one Hertz. It eliminates the need for fast clock corrections. It creates a new integrity information message capable of updating the status for 91 satellites in a single messa...

Sbas Ionospheric Performance Evaluation Tests

Satellite Based Augmentation systems (SBAS) provide to Global Navigation Satellite Systems (GNSS) users with an extra set of information, in order to enhance accuracy and integrity levels of GNSS stand alone positioning. In this context, different test methods to analyze the ionospheric corrections performance are presented. The first set of tests involves two of the ionospheric calculations th...
