Abstract:
Centimetre-level Global Navigation Satellite System (GNSS) based positioning is increasingly relevant for a large number of applications. Currently, this level of GNSS positioning accuracy is most commonly achieved using the conventional Real Time Kinematic (cRTK) method. In order to achieve such high-accuracies with cRTK, the distance (baseline) between the user and reference station must typically be shorter than 50 km for dual-frequency GNSS receivers. To address the limitations of cRTK, the Precise Point Positioning (PPP) method, which does not require local reference networks, was develop

Abstract:
Laser altimetry and satellite gravity surveys indicate that the St Elias Icefields are currently losing mass and are among the largest non-polar sea level contributors in the world. However, a poor understanding of glacier dynamics in the region is a major hurdle in evaluating regional variations in ice motion and the relationship between changing surface conditions and ice flux. This study combines in-situ dGPS measurements and advanced Radarsat-2 (RS-2) processing techniques to determine daily and seasonal ice velocities for the Kaskawulsh Glacier from summer 2009 to summer 2011.

Abstract:
This diploma thesis deals with the Precise Point Positioning (PPP) method in various variants. The thesis describes the theoretical foundations of the PPP method and the most important systematic errors that affect accuracy. The accuracy of the PPP method was evaluated using data from the permanent GNSS station CADM, which is part of the AdMaS research center. Data of the period 2018 – 2019 were processed. The results of combinations of different GNSS and the results of different observation periods were compared. Finally, the accuracy was verified at 299 IGS GNSS stations.

Abstract:
GPS processing, like every processing method for geodetic applications, relies upon least-squares estimation. Quality measures must be defined to assure that the estimates are close to reality. These quality measures are reliable provided that, first, the covariance matrix of the observations (the stochastic model) is well defined and second, the systematic effects are completely removed (i.e., the functional model is good). In the GPS precise point positioning (PPP) the stochastic and functional models are not as complicated as in the differential GPS processing. We will assess the quality of

Abstract:
Utvecklingen av satellitbaserad positionsbestämning gör det idag befogat att begära låga osäkerheter med GNSS. Det är idag möjligt att uppnå osäkerheter kring centimetern. Bäst mätosäkerhet ger relativ mätning som sker med stöd av antingen enkelstations- eller nätverks-RTK. I Sverige erbjuder Lantmäteriet med sitt SWEPOS ett tätt referensnätverk som förser användaren med korrektionsdata oavsett position inom Sveriges gränser. Dock är det inte alla länder som kan erbjuda denna positionstjänst. Geografiskt stora länder har mycket svårt att skapa ett referensnät, det skulle betyda flera tusen sta

Abstract:
Vid GNSS-positionering i samband med fastighetsbildningsåtgärder används vanligtvis den traditionella RTK-mätningen (Real-Time Kinematic) via SWEPOS nätverks-RTK-tjänst. Denna tjänst kräver mobiltelefontäckning eller motsvarande tvåvägskommunikation, vilket kan vara problematiskt inom områden med bristfällig mobiltelefontäckning. Under dessa förhållanden kan istället PPP-mätning (Precise Point Positioning) vara användbart vid fastighetsbildningsåtgärder då dessa tjänster tar emot korrektionsdata i realtid från satelliter. PPP kräver inte någon mobiltelefontäckning, däremot krävs en kommunikati

Abstract:
Precise Point Positioning (PPP) provides GNSS navigation using a stand-alone receiver with no base station. As a technique PPP suffers from long convergence times and quality degradation during periods of poor satellite visibility or geometry. Many applications require reliable realtime centimetre level positioning with worldwide coverage, and a short initialisation time. To achieve these goals, this thesis considers the use of GLONASS in conjunction with GPS in kinematic PPP. This increases the number of satellites visible to the receiver, improving the geometry of the visible satellite const

Abstract:
Precise Point Positioning (PPP) ermöglicht eine präzise Positionsbestimmung mittels globaler Satellitennavigationssysteme (Global Navigation Satellite System, GNSS) ohne die direkte Verwendung der Beobachtungsdaten von regionalen Referenzstationen. Die wesentlichste Einschränkung von PPP im Vergleich zu differenziellen Auswertetechniken (Real-Time Kinematic, RTK) ist die deutlich längere Konvergenzzeit. Voraussetzung für die Verkürzung der Konvergenzzeit ist die Festsetzung der geschätzten Mehrdeutigkeiten auf ganzzahlige Werte. Die Mehrdeutigkeitslösung verlangt ein robustes funktionales Mode
