Question:
My Raymarine multifunction display no longer receives WAAS Satellite Differential corrections after recent changes to the satellites involved. How can I restore this capability to my system?
Answer:
The Federal Aviation Administration (FAA) recently decommissioned two WAAS GPS satellites (PRN 122 and PRN 134), and then activated two replacement satellites (PRN 135 and PRN 138). The WAAS firmware in certain Raymarine products does not recognize satellites 135 or 138. All of the Raymarine products affected continue to receive the standard GPS signals and therefore are safe for navigation.
We are pleased to release a software update for Raymarine C- Series (C70, C80, C120) and E-Series (E80, E120) Multifunction Displays that restores the ability for their connected Raystar GPS sensors to detect, track and utilize the new WAAS PRN 135 and 138 satellites.
