Recent Developments in Precise Point Positioning
GEOMATICA, 2012In standard Precise Point Positioning (PPP), the carrier phase ambiguities are estimated as real-valued constants, so that the carrier-phases can provide similar information as the pseudoranges. As a consequence, it can take tens of minutes to several hours for the ambiguities to converge to suitably precise values.

Multi-GNSS Single Frequency Precise Point Positioning [PDF]
2018 IEEE International Workshop on Metrology for the Sea; Learning to Measure Sea Health Parameters (MetroSea), 2018 Single Frequency-Precise Point Positioning (SF-PPP) processing strategy is a hot topic in GNSS context, owing to the advantages of a stand-alone, accurate and cost efficiency positioning. However, the existing SF-PPP methods can be hardly implemented for high-precision applications due to the large error sources that affect accuracy and converge time ...

Smartphone Applications for Precise Point Positioning
ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2017C.N.E.S., the French Space Agency, introduces two smartphone applications for Precise Point Positioning. The first application is a converter to RTCM format. It allows to send smartphone measurements (code, phase, Doppler) to a caster in the well-known RTCM standard.

Precise point positioning with multiple Galileo frequencies
2008 IEEE/ION Position, Location and Navigation Symposium, 2008Precise point positioning is analysed with new ionosphere-free mixed code-carrier combinations of satellite-satellite single difference (SD) measurements. The large wavelength of 3.215 m and the low noise level of 3.76 cm of an L1-E5 linear combination enable reliable fixing of ambiguities with a sequential bootstrapping and an integer decorrelation ...

2017
Since its introduction in 1997, precise point positioning (PPP ) offers an attractive alternative to differential global navigation satellite system (GNSS ) positioning. The PPP approach uses undifferenced, dual-frequency, pseudorange and carrier-phase observations along with precise satellite orbit and clock products, for standalone static or ...

Precise Point-to-Point Positioning Control of Flexible Structures
Journal of Dynamic Systems, Measurement, and Control, 1990Control strategies to accomplish precise point-to-point positioning of flexible structures are discussed. First, the problem is formulated and solved in closed form using a linear quadratic optimal control technique for a simple system with only one rigid and one flexible mode; the resulting analytical solutions are examined in both the time and ...

Ambiguity Resolution with Precise Point Positioning
2014Ambiguity resolution with PPP aims at effectively reducing the long convergence time. The research in this dissertation explores its potential for both dual-frequency signals and triple-frequency signals. One of the most popular PPP ambiguity resolution strategies with dual-frequency GNSS signals is to first fix the L1/L2 wide-lane ambiguities in the ...

Precise point positioning degradation in the presence of a SITEC [PDF]
2015 1st URSI Atlantic Radio Science Conference (URSI AT-RASC), 2015 The ionosphere is one of the main contributors to errors in the GNSS satellite-receiver ranging. In dual frequency precise point positioning (PPP) ionospheric effect may be reduced by means of the ionospheric-free linear combination (Zumberge et al., J. Geophys. Res. 102 (B3), 1997, pp. 5005–5017).

Gps precise point positioning with kinematic data
Pollack Periodica, 2011Nowadays most of the users needing geodetic accuracy use the Global Positioning System (GPS) with static measurements or with RTK (Real Time Kinematic) measurements. Few seconds are available to measure a detail point, therefore only the RTK method can satisfy the expectations.

Precise Point Positioning for Next-Generation GNSS
2020 European Navigation Conference (ENC), 2020Precise Point Positioning (PPP) provides accurate absolute position information without the direct need of measurements from a reference station at the user. The current challenge of GPS L1/L2-based PPP is its long convergence time of more than 20 minutes being caused by the need to estimate atmospheric parameters, and the relatively large code noise ...
