Global positioning accuracy improves

Abstract

Racal Positioning Systems Ltd. is now incorporating Ashtech's newest and most accurate Global Positioning System (GPS) receivers in its DeltaFix short‐range (SR) differential GPS systems.The differential system offers users precise positioning—at ranges depending on local radio propagation conditions—up to 60 km from a shore‐based reference station. The system was developed for users needing high‐accuracy DGPS positioning over relatively small areas.
