Analysis of the Tropospheric Doppler Radar Wind Profiler Measurement Accuracy

- The Tropospheric Doppler Radar Wind Profiler (TDRWP) is a wind measurement instrument at NASA’s Kennedy Space Center, co-located on the United States Space Force’s (USSF) Eastern Range (ER) at the Cape Canaveral Space Force Station (CCAFS), that generates atmospheric wind profiles which are utilized in the design, certification and operations of various launch vehicles
- NASA’s Space Launch System (SLS)
- Commercial launch vehicles
- NASA Crew-4 in April 2022 was first NASA crewed mission to use TDRWP
- Composed of twenty antenna sectors and transmitter unit pairs which operate at 48 MHz
- TDRWP data is required for day-of-launch structural margin and performance assessments
