“…Buoys equipped with GPS receivers have been used to measure water levels, atmospheric parameter and other physical conditions in sea, river or lake for the purposes of navigation, tide correction, the altimeter range calibration, ocean environment and pollution monitoring, flood control, and fisheries (Rocken et al 1990, Key et al 1998, Moore et al 2000. For high positioning accuracy applications, the relative positioning RTK technique is widely adopted in most of GPS buoy positioning.…”

Abstract. In this paper, the basic precise point positioning model has been reviewed. A recursive least square algorithm that separates the position coordinates and other parameters, such as ambiguities and tropospheric delays, is proposed for kinematic PPP applications. A test was carried out to test the method proposed in this paper, which made use of a GPS buoy equipped with a pressure and a tilt meter to monitor the sea level in Hong Kong. The initial results from kinematic PPP positioning compared with conventional kinematic positioning methods shows the accuracy of decimetre level positioning accuracy can be achieved by the PPP method.

Abstract. In this paper we present a novel method to determine the time of occurrence of tidal slack with a GPS receiver mounted on an anchored buoy commonly used to delineate shipping lanes in estuaries and tidal channels. Slack tide occurs when the tide changes direction from ebb to flood flow or from flood to ebb. The determination of this point in time is not only useful for shipping and salvaging, it is also important information for calibrating tidal models, for determining the maximum salt intrusion and for the further refinement of the theory on tidal propagation. The accuracy of the timing is well within 10 min and the method -able to operate in real time -is relatively cheap and easy to implement on a permanent basis or in short field campaigns.

“…In contrast to marine sciences the use of GNSS techniques for water elevation measurement of rivers, especially for continuous monitoring, is practically unknown. The only notion of using the techniques was given by [Moore et al, 2000], where laboratory experiments and a short term test of a GPS buoy on a river yielded promising results. To our knowledge, also industrial developments do not exist in this respect.…”
