ADR (Accumulated Doppler Range) is calculated as follows:

ADR_ROLLS = ( -RGED_PSR / WAVELENGTH  - RGED_ADR) / MAX_VALUE

IF (ADR_ROLLS 

≤ 

-0.5)

ADR_ROLLS = ADR_ROLLS - 0.5

ELSE

ADR_ROLLS = ADR_ROLLS + 0.5 

CORRECTED_ADR = RGED_ADR + (MAX_VALUE * ADR_ROLLS)

ADR has units of cycles
WAVELENGTH = 0.1902936727984 for L1
WAVELENGTH = 0.2442102134246 for L2
MAX_VALUE = 8388608
