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 ...

Multi-GNSS Single Frequency Precise Point Positioning
2018 IEEE International Workshop on Metrology for the Sea; Learning to Measure Sea Health Parameters (MetroSea), 2018Single 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 ...

Lane Determination With GPS Precise Point Positioning
IEEE Transactions on Intelligent Transportation Systems, 2017Modern intelligent transport solutions can achieve an improvement of traffic flow on motorways. With lane-specific measurements and lane-specific control, more measures are possible. Single frequency precise point positioning (PPP) is a newly developed and affordable technique to achieve an improved position accuracy compared with global positioning ...

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 ...

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.

Frequency transfer using precise point positioning
18th European Frequency and Time Forum (EFTF 2004), 2004Using precise point positioning (PPP) we show the potential for comparing frequency standards with time stabilities of under 300 ps in flicker phase noise for time periods of 1 to 10 d. This leads to comparisons at 1 part in 1015 or better at 10 d. We compare short baseline PPP results with 2 hour data from the NIST Measurements System.

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-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 ...
