A simplified model of global navigation satellite system (GNSS) radio occultation (RO) observations tracks the tangent point between transmitter and receiver satellites. Observations impose specific constraints on the tangent point and produce linear profiles through the atmosphere, rather than spatial regions like imaging-style sensors.
