Opinions Transportation Expert Advice: Availability Gaps: Solutions for Aviation Published December 1, 2009 By GPS World Staff Join the Discussion Recent attention given to aging GPS satellites and availability gaps from lagging constellation replenishment have provoked deep concern, particularly within the aviation community. Available remedies include exploitation of well known but unused methods plus new techniques; those discussed here have future relevance, with or without availability gaps. Even with far greater coverage from multiple GNSS, crises could emerge from severely stronger interference levels or other unforeseen events. Advance preparation for any such occurrence would avoid the waste, confusion, and blind alleys that generally arise with the sudden appearance of an emergency. Read more » aviation Expert Advice
Opinions SBAS Survey As Loran Fades, Attention Shifts to DGPS and SBAS Published November 30, 2009 By Eric Gakstatter Join the Discussion Few precise-positioning users have employed Loran in a professional sense, although maybe you have in your personal life if you’re a airplane pilot or a mariner. Then again, if you've flown as an airline passenger or cruised onboard a ship, you've benefited from the back-up to GPS that Loran provides. That back-up is about to go away. As attention and resources shift away from Loran, they focuses more intensely on GPS augmentations, specifically differential GPS (DGPS) and satellite-based augmentation systems (SBAS) such as WAAS and EGNOS.
