Space Res., 2009 #week 1597: goa-test.2010.09.20c More recent version, close to future 6.0 official version for tests #week 1599: goa-test.2010.05.25h Back to previous test version #week 1606: goa-6.0 Latest JPL official version 4) Global Statistics ==================== GPS week number 1607 from 24-10-2010 to 30-10-2010 Total number of stations = 44 Total number of satellites = 3 Combinations
