GPS Receiver Performance Evaluation
| Abstract: | The proliieration of GPS receivers is at an all time high and growing with no peak in sight. Each year, manufacturers are introducing new products and new capabilitiis at lower prices. GPS receivers are available for practically every application and price range. Manufacturers of GPS receiver products with similar features and capabilities often quote similar ‘classic’ performance specifications. So then a buyer is left with the question, “Are a// GPS receivers created equal? This paper describes a comparison test of 15 GPS receivers tracking on-orbit satellites for a one hour time period. There are many aspects of GPS receiver characterization. The objective of this test was to demonstrate the distinctive position accuracy performance capabilities of various GPS receivers and receiver configurations by capturing a ‘snap-shot’ in time of GPS receiver position accuracy perfor- mance. Precise Positioning Service, Standard Positioning Service, and Differential GPS receivers were examined in this test. Receivers possessing various numbers of channels and tracking capabilities were also included in this test. The resutts of this comparison test demonstrated expected differences between the various classes of service and tracking capabilities. Additionally, this test uncovered previously unknown bugs in some of the subject receivers. |
