FR-1
FR-1 was France's first scientific satellite and the first CNES scientific satellite, built in cooperation with CNET and NASA. Its experiments studied the propagation of very-low-frequency radio waves through the ionosphere and magnetosphere and measured local electron density.

- Description
- FR-1 was France's first scientific satellite and the first CNES scientific satellite, built in cooperation with CNET and NASA. Its experiments studied the propagation of very-low-frequency radio waves through the ionosphere and magnetosphere and measured local electron density.
- Destination
- Circular, near-polar Earth orbit at approximately 750–800 km for measurements of very-low-frequency wave propagation in the ionosphere and magnetosphere and local electron density
- End Date
- 1969-03-01
- Outcome
- Successful. NASA's Scout X-4 placed FR-1 into a circular, near-polar Earth orbit on 6 December 1965, and the satellite functioned in orbit. The experiment continued far beyond its planned three-month lifetime: scientific measurements were pursued until equipment degradation in August 1968; the spacecraft then continued transmitting operational information until 1 March 1969. NASA reported at least 19 scientific publications from the cooperative VLF study.
