... Recommendation 4. The United States single photon detectors, additional laser wavelengths, should establish and maintain a high-precision GNSS/GPS shorter acquisition times and faster slewing, real-time national network constructed to scientific specifications, data evaluation for quality control, and autonomous capable of streaming high-rate data in real time.

... While NASA makes a a student fellowship program, but it primarily funds strong commitment to the international GNSS geodetic students who study science applications of geodesy, infrastructure and the terrestrial reference frame, it relies rather than those who improve geodetic techniques on other agencies to densify it in the United States.

... It is also at risk of losing redundancy (and hence validation capability) The United States continues to make a strong in the highest-grade geodetic data analysis software, contribution to the international geodetic infrastruc- independently written and maintained by more than ture with significant participation and leadership in one research group.
