There will be and attempt to contact Pioneer 10 this week, March 3, 4, and
5.

Earth has come around the Sun and will be directly within Pioneer 10's
antenna pattern, if an antenna pattern there might be. Might be, because
the fixed frequency oscillator is dead and the only way to wake up the
spacecraft is to send up a strong signal which will wake up the variable
frequency oscillator and let the spacecraft send back a signal at a known
offset from what it sees coming up.

This will be the last time Earth will be here as the Sun drags us along as
it goes on its way around the Solar System. Each year Earth moves over just
a bit in space and in the past you could command Pioneer 10 to re-align
itself to look at a 400 KW up-link signal from Earth but there is not enough
power on board Pioneer 10 to do that now and no one is sending commands
anyway. [Mission long over and I took all the equipment out of the Pioneer
Operations space, sorry.]

unless you have the time for them to down load. :-( ]

If Pioneer 10 is heard from then maybe they will get some Radio Science and
some Doppler information that will give one more data point in understanding
the Pioneer Anomaly. The Pioneer Master Data Records that have been saved
are also being used to understand what the spacecraft was doing for 30
years.

I don't think there will be any data received from the spacecraft even if it
is heard from as there have been hardware modifications at the Deep Space
Network that took out some of the old equipment that was used in decoding
the down link, and of course there isn't any hardware at all to look at the
data where I used to work. [Those pictures above that you didn't look at.]

Will let you know if I hear of any successes in listening to the old bird.
:-)

Thanks for looking up with me.

[Second page of a 12 page Power Point presentation describing the upcoming
support. Good luck in understanding the acronyms. - LRK -]

* Three Supports performed over three days
-- DOY 062, 063, and 064 (March 3, 4, and 5)
* 70-m antenna used
* 400 kW uplink power
* Three different tune profiles for capturing the transponder
* Antenna's low noise path utilized
* Radio Science monitoring downlink for signal detection
* DTT system configured for throughput mode if acquisition is achieved.
* NOPE monitoring supports in ROC
* The Pioneer 10 RTLT is 24:56:25 (hh:mm:ss)

DTT Downlink Telemetry and Tracking Subsystem
Successor to the BVR in the NSP era.

NOPE Network Operations Project Engineer

BVR Block V Receiver
Standard DSN telemetry receiver: input typically two 300 MHz I.F.s, output
two digital data streams. This will be replaced by the DTT in the NSP era.

NSP Network Simplication Plan
Upgrade of the DSN controller subsystems

ROC ???
