Customizing ArcReader to support GPS Kelly Johnston Indiana Department of Environmental Management
the task…Give mobile users without an ArcGIS license access to a location-enabled GIS viewer. …mobile users… Field inspectors / Law enforcement / Public Safety laptop computers / limited network connections …without an ArcGIS license… casual users / can’t justify $ for GIS software …location-enabled… live input from a GPS device update a map display to the current location. …GIS viewer… no requirement to update or edit data

my question…“Seems GPS is not something ArcReader explicitly supports, but I'm wondering…is it possible?”
my question…“Seems GPS is not something ArcReader explicitly supports, but I'm wondering…is it possible?” • the first answer… “As far as your question goes - ArcReader, unfortunately, does not offer GPS capability. You would have to deploy either an ArcPad solution or an ArcView solution to get the GPS option. Let me know if that helps you out.”

ArcReader – how can it be customized? ESRI Publisher Library Reference The ArcReader application cannot be customized and extended in the same way as other ArcGIS Desktop products. Instead, developers can use the ArcReaderControl to build and extend Windows applications with custom ArcReader functionality. for example…

customizing ArcReader – write code to interpret GPS input sentences…
