Performance of Precise Point Positioning using Current Triple-frequency GPS Measurements in Australia
GNSS Network Real-Time-Kinematic (NRTK) has become a common service for many precise positioning applications over the last two decades. However, NRTK cannot service or support user applications if they are outside the Continuously Operating Reference Stations (CORS) network coverage area, such as in the case of offshore surveying. In addition, NRTK requires a fairly dense network of CORS (typi...
متن کاملFrequency Transfer Using Precise Point Positioning
Using 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 10 or better at 10 d. We compare short baseline PPP results with 2 hour data from the NIST Measurements System. We compare results from the NIST – USNO baseline with hourly...
متن کاملGPS Precise Point Positioning Using IGS Orbit Products
The International GPS Service (IGS) has provided GPS orbit products to the scientific community with increased precision and timeliness. Many users interested in geodetic positioning have adopted the IGS precise orbits to achieve centimeter level accuracy and ensure long-term reference frame stability. Currently, a differential positioning approach that requires the combination of observations ...
متن کاملPrecise Point Positioning Using Combined GPS and GLONASS Observations
Precise Point Positioning (PPP) is currently based on the processing of only GPS observations. Its positioning accuracy, availability and reliability are very dependent on the number of visible satellites, which is often insufficient in the environments such as urban canyons, mountain and open-pit mines areas. Even in the open area where sufficient GPS satellites are available, the accuracy and...
متن کاملPrecise Point Positioning Using Triple GNSS Constellations in Various Modes
This paper introduces a new dual-frequency precise point positioning (PPP) model, which combines the observations from three different global navigation satellite system (GNSS) constellations, namely GPS, Galileo, and BeiDou. Combining measurements from different GNSS systems introduces additional biases, including inter-system bias and hardware delays, which require rigorous modelling. Our mod...
