About your source-code
Dear author,
I have some questions and comments about your GNSS source code.
Could you tell me answers of following my questions?
main.cpp
・Why are you deleting C02 of BeiDou in line 44?
・Why are you set the time as 307000 in line 69?
・Maximum number of BeiDou satellite will be 35 in the future, so the more large value should be assigned to BeiDou, I think. For example, 70→110.
・Is this program only for L1 single frequency? What if the data have only BeiDou or Glonass?
calc_sat_pos.cpp
・I think myu and omegae are inorrect for BeiDou and Galileo.
・Why are you using 302400 in line 68 and 70?
rinex_time.cpp
・(Around line 26) If we use whole day brdm ephemeris, the first navigation message is much earlier than the observation time. Then the first few epochs will be skipped. So while loop should be used to match the exact time.
calc_tropo.cpp
・(From line 35) UNB3 or EGNOS or GPT model is better than Saastamoinen model and their precision is about 5-8 cm. So these are better for SPP and PPP. But there is not so much difference as for RTK.
