4 ADR (Accumulated Doppler Range) is calculated as follows:
ADR_ROLLS = ( -RGED_PSR / WAVELENGTH - RGED_ADR) / MAX_VALUE
Round to the closest integer
IF (ADR_ROLLS -0.5)
ADR_ROLLS = ADR_ROLLS - 0.5
ELSE
ADR_ROLLS = ADR_ROLLS + 0.5
At this point integerise ADR_ROLLS
CORRECTED_ADR = RGED_ADR - (MAX_VALUE * ADR_ROLLS)
where:
ADR has units of cycles
WAVELENGTH = 0.1902936727984 for L1
WAVELENGTH = 0.2442102134246 for L2
MAX_VALUE = 8388608
