| 摘要： | The aids to navigation positioning programs AAPS 3.4, ATONIS/AAPS 4. 0, and ECPINS/ATON 1.73 were tested for the accuracy of determining range and bearing when used to position floating aids to navigation. These calculations are the key element in determining when an aid is on station, so these programs must yield consistent and correct results. The USCG R&D Center in Groton, CT, conducted the tests by comparing the program output to independently calculated results developed using algorithms obtained from the National Geodetic Survey. Test points at various places around the world were generated to test all possible combinations of quadrants and hemispheres. Both ATONIS/AAPS 4.0 and AAPS 3.4 were found to be accurate to within 0.5 inches in range and within .01 degrees in bearing to the calculated truth measurements. ECPINS/ATON 1.73 was found to be accurate within five inches in range, and .01 degrees in bearing. The Differential Global Positioning System receivers used to position are accurate to two yards so these small differences in range would not be noticeable. All three positioning programs can effectively be used interchangeably and achieve equivalent results. |
