Dale Ireland asked: > What is the policy regarding posting radio observations on SEESAT? SeeSat-L is devoted to visual observation; therefore, radio observations have not been welcome; however, I have long believed that radio observations that complement visual observation should be welcome. Indeed, radio and visual observations are highly complementary for tracking. Using typical hobbyist equipment, visual observers are able to produce the most accurate positional data; however, they cannot observe in daylight or through clouds. Radio observers do not suffer those limitations, but they can only track satellites that transmit radio waves (or reflect those of other origin), in which case their observations of Doppler-shifted frequency plots, AOS/LOS times, and transmitter on/off times are highly valuable for orbital analysis. So, I am inclined to encourage some sharing of radio observations on SeeSat-L, that complement visual observations related to tracking and orbit determination. There is room for debate on this, but it should take place off-list, either on UseSat-L, or in regular e-mail.
