The invention relates to a GNSS-assisted inertial measurement track geometrical state rapid measurement system. The system comprises a carrying platform and a measurement unit arranged on the carryingplatform. The carrying platform is a rail car; the measurement unit comprises a control terminal, a data acquisition module, a GNSS receiver and a sensor. The data acquisition module sends a measurement instruction to the sensor, receives, stores and carries out time synchronization on sensor data, and sends acquired data to the control terminal in real time; and the GNSS receiver receives GNSS signals according to the measurement instruction, transmits the received positioning information to the data acquisition module, and then sends the positioning information to the control terminal. According to the invention, the defects or deficiencies of the existing rail measuring equipment in many aspects are overcome, the efficient and accurate measurement of the geometrical state of the rail is realized, and the requirements of rail transit in China on the accurate installation and high smoothness maintenance of the rail at present are met.
