Nico Janssen, PA0DLO, noted that 18th Space Control Squadron (18SPCS) has
swapped the satellite names associated with object 41845 (was CAS-2T) and
another object 41847. Therefore CAS-2T is now object 41847. Nico's detailed
doppler measurements confirm that CAS-2T is in fact object 41847. (Note: the
payloads CAS-2T and KS-1Q still remain attached to the CZ 11 fourth stage.)
Thanks Nico, good catch!
The PICSAT team and Albert Van Duersen indicate that a better set of TLEs
for PICSAT is now object 43132. Nico Janssen has also noted that the best
TLE set for PICSAT has been unstable since November 14th of last year. Nico
says that now object 43132 and even object 43133 are better matches for
PICSAT than object 43131. Therefore, we will use object 43132 for PICSAT
for now. The problem is the closeness of objects 43131, 43132 and 43133.
Nico says he will continue to monitor these objects as they slowly separate
over time. More later.
The following satellites have been added to the AMSAT TLE Distribution this
FMN 1 (FengMaNiu 1) - NORAD CAT ID 43192.
Shaonian Xing (MXSAT-1) - NORAD CAT ID 43199.
FMN 1 is still being commissioned. It currently is transmitting telemetery
only , but it is hoped that it will activate a FM repeater soon. It is also
believed to have a multi-camera and SSTV subsystems as well. We will see.
Shaonian Xing (the official name of MXSAT-1) is a student satellite and it
is also still being commissioned. It may have a FM repeater, but we will
again have to wait and see.
D-Star One is still a mystery. We have heard no signals from it so far,
even though the owner claims all is OK??? We are still unsure which object
it is (43184, 43185, or 43188). There has no signal to track. D-Star may be
DOA (Dead On Arrival).
Thanks to Nico Janssen, PA0DLO, for above info.
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???)
