We have not turned on our UHF transmitter on CanX-2. If it were to be used, it
would only be active over our ground station in Toronto, Canada (FN03gs).
CanX-2 and CanX-6 are responding commands and both spacecraft are healthy. We
are in the process of commissioning and it is progressing well on both spacecraft.
We are tracking CanX-2 with NORAD ID 32787 and CanX-6 with 32784. We are fairly
confident in these targets because both satellites have SRS S-Band downlinks and
we have good resolution with our 2.1m dish. I believe Celestrak has assigned
those names to these objects, although it's really the NORAD names that are
These are our current observations that Freddy Pranajaya has compiled from
various reports and posted on the NLS-4 web page:
Object A - 32783 - Cartosat-2A
Object B - 32784 - CanX-6 (NTS)
We have just completed a pass, NTS is now in Application Mode.
S-band tracking seems to be very accurate on this object.
Object C - 327585 - Cute-1.7+APDII
This is based on latest observations from this morning (EDT).

Object D - 32786 - IMS-1
An inquiry has been sent to the IMS-1 team in India, to see
whether this TLE corresponds with their operations parameter.
Object E - 32787 - CanX-2
Using this object, we are tracking CanX-2 accurately with our

Object H - 32790 - (Delfi-C3 ?)
Object J - 32791 - COMPASS-1
COMPASS1 is currently working with the TLE data for object 32791.
Object K - 32792 - RUBIN-8/PSLV

An early plan for CanX-2 was to have a downlink on 2407.650 MHz. However, given
that we would be downloading data from our science experiments on this channel,
we coordinated frequencies in the Space Research Science S-band.
