On May 18, 2005, the Xi’an Branch of the Chinese Academy of Sciences (CAS) directed an appraisal on the achievement of “the R&D of Multifunctional Double-frequency Time Transmission GPS Receiver NTSCGPS-2” which took the NTSC 2 years to finish in Lintong.

The project is an important part of the “Research on Establishment and Maintenance of JATC”, an important directional program of knowledge innovation of the CAS. It is also a comparatively separate sub-topic of research. The expert group heard the working and research reports of the subject groups, and the novelty research report, test report and application certificate provided, examined relevant material and data, and tested the main functions and performance of the “multifunctional double-frequency time transmission GPS receiver NTSCGPS-2” on the spot.

After an earnest discussion, the expert group deemed with consensus that the “development of the multifunctional double-frequency time transmission GPS receiver NTSCGPS-2” is of innovation with its main technical indexes reaching the international advanced level. It is suggested that the achievement be popularized and applied at a fast pace. The project is agreed to pass the achievement appraisal in chorus.
