The Radio Occultation Experiment aboard CHAMP: Operational Data Analysis and Validation of Vertical Atmospheric Profiles (2004, methodology): “Major modifications are: use of an empiric Doppler model for plausibility control of L1 and L2 data in the lower troposphere (for details see Hajj et al., 2002); use of ECMWF data for the initialisation of the hydrostatic equation at 43 km (one atmospheric scale height above the highest data point…”
Effect of superrefraction on inversions of radio occultation signals in the lower troposphere (2003, background): “[2] Radio occultation (RO) remote sensing of the atmosphere includes transmission and reception of coherent radio signals propagating through the atmosphere between satellites (such as the Global Positioning System (GPS) and low Earth orbiting (LEO) satellites) [Melbourne et al., 1994; Hocke, 1997; ”

GPS radio occultation for climate monitoring and change detection (2011, methodology): “…of GPS satellites or of the receiving satellites can be removed by (single‐ or double‐) differencing methods using an additional non‐occulted GPS satellite as reference and by relating the measurement to even more stable oscillators (e.g., Cs‐133 atomic clocks) on the ground [Hajj et al., 2002].”
CHAMP and SAC-C atmospheric occultation results and intercomparisons (2004, methodology): “Using a procedure suggested by Hajj et al.
