A Javad GPS receiver was operated on board of the Aegeo R/V on October 8 and 9 2002.

• October 8: 9:53 UT -> 23:59 UT – RINEX 1s sampling rate – KML trajectory (pseudo-range dual-iono-free) – KML trajectory (phase)
• October 9: 00:01 UT -> 09:59 UT – RINEX 1s sampling rate – KML trajectory (pseudo-range dual-iono-free) – KML trajectory (phase)
