[CA] [CA11] Sirius XM Weather on AXIOM / SR150 Vs 200

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum jerroz99,

The performance which you have shown is that of a properly operating system. When ranged in too closely, Sirius/SiriusXM Marine Satellite Weather graphics will appear pixelated, to aid users in understanding the limits of SiriusXM SiriusXM Marine Satellite Weather data. The world map utilized by the Weather feature is not detailed, and is indicative of the fact that the resolution of SiriusXM weather is designed to support viewing weather data down to a regional area (ex. New England, the MidAtlantic region, etc.) rather than within a local are (ex. Boston Harbor, New York Harbor, etc.). For the latter, it may be more appropriate to view the weather web page for one's local network news website on one's smartphone or via the LightHouse 3 Apps feature. Regarding the latter, please click here to view a FAQ addressing this subject.

In a nutshell, Raymarine and third party SiriusXM satellite receivers are supplied with exactly the same resolution of weather data. The perception of greater resolution within one manufacturer's products is the result of smoothing algorithms designed to improve the appearance, albeit not necessarily the accuracy, of the NOWRAD data. As indicated within a related discussion within the retired Raymarine Technical Community Forum, the designers of Raymarine MFD software have opted not to employ such smoothing algorithms, as it may be misleading with respect to the resolution of the NOWRAD and other weather graphics layers. Instead, Raymarine MFDs have been designed to plot exactly the data which has received. When so plotted, this can have appearance of reduced resolution when ranged well in. When viewing NOWRAD weather, it is typically recommended that it be viewed at a regional level.
