Per detailed doppler measurements Nico Janssen, PA0DLO reports:
TianYi 2 (TY 2) is object 43155 (downlink 435.350 MHz)and TianYi 6
(TY 6) is either object 43157 or 43158. It is still not possible
to identify TY 6 (downlink 436.100 MHz, as the separation between
43157 and 43158 is still less than 1 second.
The student satellite HuaiAn 1 (HA 1) now has the post-launch name
Zhou Enlai. It is not possible to identify it, because it does
not transmit any signals. This appears to be another example of a
DOA (Dead On Arrival) student satellite.
Also on the 1/12/2018 PSLV-C40 launch, that also carried AO 92 and
PICSAT, there were six other satellites that should have a downlink
on amateur frequencies. But they all appear to be DOA satellites.
The only other satellite that does have a 70 cm downlink (unexpected)
is (probably) INS 1C, object 43116. INS 1C downlink is 435.085 MHz
with 1200 bps FSK AX.25 telemetry.
NOTE: In this week's TLE distribution object 43157 is named
2018-008C and object 43158 is named 2018-008D. These are temporary
names and when TianYi 6 is identified, one TLE will go away and the
winner will be named TianYi 6. (There are currently multiple objects
named object C and object D in Space-Track at this time???)
