text: Yo, check it out, I got a paper to discuss
  Radiation exposure, let's get on the bus
  Talkin' 'bout the Doppler Orbitography and Radiopositioning
  Integrated on Satellite, man, it's quite the mission
  
  We studied the Jason-2 oceanography clock
  A reference point, it's the cream of the crop
  Launched in '08, with a 66-degree inclination
  1336 km high, that's the elevation
  
  Over 8.5 years, we analyzed the frequency response
  Internal and external data, no need to be verbose
  ICARE-NG instrument measuring the flux
  Electrons and protons, we got the facts, no bluff
  
  T2L2 experiment, it's got the skills
  Monitoring the oscillator, no time to chill
  Few parts in 10 to the power of negative thirteen
  Compared to atomic clocks, it's so pristine
  
  With all these inputs, we built a physical model
  Describing the DORIS USO, ain't no hassle
  Fittin' the data with precision, below the limit
  10 to the power of negative twelve, we're in it
  
  This model, my friend, it's the real deal
  Assessing the Jason-3 USO, post-launch, for real
  In January 2016, it took to the sky
  Measuring radiation effects, no need to ask why
