Over the past five years, the International GNSS Service (IGS) has made continuous efforts
to extend its service from GPS and GLONASS to the variety of newly established global and …

Employ the latest satellite positioning tech with this extensive guide GPS Satellite Surveying
is the classic text on the subject, providing the most comprehensive coverage of global …

Precise point positioning (PPP) has been suffering from slow convergences to ambiguity-
fixed solutions. It is expected that this situation can be relieved or even resolved using triple …

The latest generation of GNSS satellites such as GPS BLOCK-IIF, Galileo and BDS are
transmitting signals on three or more frequencies, thus having more choices in practice. At …

At present, the BeiDou system (BDS) enables the practical application of triple-frequency
observable in the Asia-Pacific region, of many possible benefits from the additional signal; …

This study evaluates the feasibility of achieving improved positioning accuracy with raw
GNSS measurements from recently released smartphones. Using Precise Point Positioning …

Carrier phase ambiguity resolution over long baselines is challenging in BDS data
processing. This is partially due to the variations of the hardware biases in BDS code signals …

One of the most significant advantages of multiple frequencies is that it can improve the
success rate of ambiguity resolution, such as the three-frequency carrier ambiguity …

In multi-frequency and multi-constellation GNSS applications, the multi-frequency carrier
ambiguity resolution (MCAR) is the prerequisite of high-precision positioning and …

This chapter introduces the BeiDou (COMPASS) Navigation Satellite System from its early
stage as a demonstration system to its evolution to a global system. First, the development …
