We test the suitability of short-occupation differential and absolute positioning methods using data from a 13 station global positioning system (GPS) network that spans the Santa Ana Volcano and Coatepeque caldera of western El Salvador for monitoring intereruptive activity and tectonic movements near these potentially hazardous features. Data spanning a 1 yr period from 12 GPS benchmarks located 1.9 km to 9.7 km from a continuous reference GPS station were processed with Trimble differential processing software to determine the repeatabilities and hence precisions of the differential station coordinates. For observation sessions spanning 20 min, the coordinates of the benchmark closest...
