GPS Is Changing...a Lot
Track: Surveying
Author(s): Eric Gakstatter

ArcPad users around the world are challenged to keep current with evolving satellite systems. There are new GPS satellites being launched and new GPS signals being broadcast with more being planned. Russian GLONASS and planned European Galileo satellite systems are experiencing change and advancement.

Not only are the satellite systems changing but also GPS augmentation systems such as WAAS, DGPS, EGNOS, MSAS and GAGAN systems. Many ArcPad users take advantage of these GPS augmentation systems and should be aware of how they are evolving.

How do these changes affect spatial data collection and navigation services within ArcPad 7.x? Which factors should one consider when using these different satellite systems. What are the current trends and developments that one should consider when preparing GPS mapping hardware budgets in the coming year(s)?
