The PRN number for the identified GPS satellite


An array containing the visible GPS satellites is determined before every plugin Evaluate() call. The number of GPS satellites that are visible at the current time can be found using the NumSatsVisible property. The index number identifies a particular GPS satellite from that array (index 0 is the first satellite, index NumSatsVisible-1 is the last satellite). Use the GPS_PRN() method to identify the PRN from the index number if it is needed. The size of the array and even the order of the GPS satellites in the array may change between different Evaluate() calls; therefore, you can only associate an particular index number with a particular GPS satellite during the same Evaluate() call---you cannot, for example, determine during one call that index 0 is PRN 24 and believe that index 0 will continue to be asscoiated with PRN 24 on a later Evaluate() call.
