I tried to convert measurement time by this document 's instruction for each of constellationType and found that for constellationType=3 (GLONASS), the difference between converted value (tRx by the document) and ReceivedSvTimeNanos equal 𝑁𝑢𝑚𝑏𝑒𝑟𝑁𝑎𝑛𝑜𝑆𝑒𝑐𝑜𝑛𝑑𝑠𝐷𝑎y + transmitted time for some timestamp, which mean that I should use np.ceil instead of np.floor in dayNumberNanos calculation. What does this mean ?
