IALA Guideline 1152 on the SBAS Maritime Service book

On 13 December 2019, the IALA Council 70 approved the IALA Guideline 1152 on SBAS Maritime Service. This Guideline is intended to support those maritime administrations evaluating the possibility to rationalize their DGPS services, since SBAS can be considered as a backup solution for DGNSS or as a complementary means to provide augmentation to mariners.

Maritime administrations can take advantage of the use of SBAS, which provides enhanced performance over the capabilities of GNSS constellations. SBAS improves the accuracy and reliability of GNSS by correcting signal measurement errors and by providing information about the accuracy, integrity and availability of GNSS signals.

IALA Guideline 1152 identifies those aspects that maritime or coastal administrations should take into account when considering the use of SBAS by vessels navigating in their waters. The guideline provides the description of all the SBAS elements relevant to the maritime administrations, considering the use of the SBAS Signal in Space onboard vessels. This includes the reference requirements, the user equipment, and also the description of the service and the operational scheme. The document is available for download at IALA website.
