WebGNSS strictly at low tides, in order to cover as much extent into the sea as possible. A level of –1.5m were often achieved away from the shore into the sea. Plate 1, shows the GNSS base station and the rover at bench mark ME2 Plate 1: GNSS equipment setup on survey stations spacing were traversed following the Hypack Software Web2. GNSS COMPONENTS The GNSS consist of three main satellite technologies: GPS, Glonass and Galileo. Each of them consists mainly of three segments: (a) space segment, (b) control segment and (c) user segment. These segments are almost similar in the three satellite technologies, which are all together make up the GNSS.
