Experimental assessment of the time transfer capability of precise point positioning (PPP)
Proceedings of the 2005 IEEE International Frequency Control Symposium and Exposition, 2005., 2006In recent years, many national timing laboratories have installed geodetic global positioning system (GPS) receivers together with their traditional GPS/GLONASS common view (CV) receivers and two way satellite time and frequency transfer (TWSTFT) equipment.

Fixed ambiguity Precise Point Positioning (PPP) with FDE RAIM
Proceedings of the 2012 IEEE/ION Position, Location and Navigation Symposium, 2012Precise Point Positioning (PPP) has been one of the major research interests in the Global Navigation Satellite System (GNSS) research field in recent years. PPP is a promising method because it can provide centimeter level positioning accuracy by using only one GNSS receiver, without using local reference networks.

Performance evaluation of BDS-3 PPP-B2b precise point positioning service
GPS Solutions, 2021A new precise point positioning (PPP) service has been provided by BeiDou global navigation satellite system (BDS-3). The correction parameters, including precision orbit correction, clock offset correction and differential code bias, are transmitted by PPP-B2b signal from BDS-3 geosynchronous orbit satellites.

Triple carrier precise point positioning (PPP) using GPS L5
Survey Review, 2013The latest generation of GPS satellites, block IIF, include for the first time a new civil signal on L5 frequency (1176·45 MHz), in addition to the legacy signals on L1 (1575·42 MHz) and L2 (1227·60 MHz). Traditional precise point positioning (PPP) is based on L1/L2 dual-frequency observations to remove the ionospheric delay.

Precise Point Positioning (PPP) using Low-Cost and Ultra-Low-Cost GNSS Receivers
ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2017Few decimetre to metre level accuracy is possible using the cellphone grade GNSS hardware. Current low-cost and ultra-low-cost (cellphone) GNSS receivers have no dual-frequency observables to form linear combination, in-order to account for the ionospheric delay. Global Ionospheric Maps (GIM) are used to mitigate the ionospheric error.

The Performance Analysis of Multi-system Integrated Precise Point Positioning (PPP)
2016Based on the analysis of the GNSS navigation and positioning, this paper studies the key technology and superiority of the PPP based on single difference between satellites. The true observation data are used to compare and analyze the precision and convergence time of PPP based on GPS\GLONASS, GPS\BDS dual system, and GPS\GLONASS\BDS triple system ...

Performance of Precise Point Positioning (PPP) Based on Uncombined Dual-Frequency GPS Observables
Survey Review, 2011AbstractA new PPP algorithm based on uncombined dual-frequency GPS code and phase observables is presented. The algorithms different from traditional ones in which the ionosphere-free code and phase observables are formed. The Line Of Sight (LOS) ionospheric delays are taken as estimate parameters by introducing the constraints of between-epoch ...
