Seismic measuring system including GPS receivers
First Claim
1. A deformation monitoring system including:
- one or more base receivers for receiving global navigation satellite system signals that are used to determine global position and having associated antennas with substantial views of the sky, the one or more base receivers acquiring and tracking the satellite signals and providing range information;
a plurality of slave receivers for receiving the global navigation satellite system signals, the slave receivers being selectively located over the site being monitored, the slave receivers acquiring and tracking the satellite signals and providing range information; and
a data recording and control center forcollecting the range information over an extended period of time and batch processing the information to determine which respective range data are valid and calculate the positions of the respective slave receivers using the valid range data, andanalyzing the calculated positions to determine movement that indicates deformation.

Abstract
A deformation monitoring system includes a data recording and control center, one or more base receivers with associated antennas that have a substantially unrestricted view of the sky and acquire and track satellite signals used for global positioning and slave receivers at various locations over the site being monitored, the slave receivers also acquiring and tracking the satellite signals. The system processes range information provided by the slave receivers over an extended period of time to determine the positions of the respective slave receivers. In this way, the precise positions of the respective slave receivers can be calculated, even if the slave receivers are able to observe and collect data from one or more satellites for only three or four relatively short time intervals at various sky positions during the extended period.
