The Accuracy of Global Positioning System (GPS) Station Configuration is a key to any scientific research involving GPS data. Many types of random errors or biases affect both GPS pseudo range and carrier phase measurements. These errors may arise from satellite, receiver or due to signal propagation. This research intends to employ Mean Square Error Analysis among other techniques that could be used in the evaluation of GPS Station configuration. The study involves two Continuously Operating Reference (COR) stations, one from Mpape and the Other one from National Space Research and Development (NASRDA), both in Abuja; with none of them as reference station. The study revealed that station-specific factors (geometry, local environment, antenna setup or processing choices) control whether vertical or horizontal errors dominate; therefore station-level diagnostics: Dilution of Precision (DOP) values, multipath indicators, residual time series; should be examined before combining stations or generalizing accuracy estimates.

This study was carried out to identify shallow aquifers in a number of villages in Southern Ughelli North and the Patani Local Government Area of Delta State, in Southern Nigeria, using vertical electrical sounding (VES) with the Schlumberger electrode configuration.
