Assessment of the Feasibility of PPP-B2b Service for Real-Time Coseismic Displacement Retrieval

Remote Sensing, 2021
Traditional coseismic displacement retrieval generally uses real-time kinematic (RTK) and precise point positioning (PPP) services. However, both RTK and real-time PPP need a network link to transmit the corrected data.
