Hi Rob: Thanks for the link. These pdf docs have pretty good bookmarks. They made it easy to find this: 20.3.3.8.2 GPS and GNSS Time. The GPS/GNSS-time relationship is given by, tGNSS = tE – (A0GGTO + A1GGTO (tE – totGGTO + 604800 (WN – WNotGGTO) + A2GGTO (tE – totGGTO + 604800 (WN – WNotGGTO))2) where tGNSS is in seconds, tE and WN are as defined in Section 20.3.3.5.2.4 of IS-GPS-200, and the remaining parameters are as defined in Table 20-XI. Apparently there is a bias offset and drift between GPS time and GNSS time.
