Bill: Is there anyway the Voyagers can test this hypothesis?


JPL continues to communicate with the Voyagers -- commands up, telemetry
down -- but we have not requested any radio tracking data for either
Voyager since October 1992. Our final trajectory update, issued in
March 1993, was believed then to be accurate enough (less than 0.01
degree geocentric) to keep the spacecraft within the beamwidth of the
DSN 70 meter antennas through at least 2019. The last two solutions for
Voyager 2, done one year apart, differ by about 1 arcsec in 2020. (I
still have the memo that documented the final solution, and I'm looking
at it as I write this. Some things are worth keeping.) So from both an
engineering and a budget standpoint there was no more reason to continue
to collect tracking data.

It's too late to test your hypothesis with Voyager 1. It's uncertain
that Voyager 2 will reach the heliopause before its power runs out.

Do this indicate that
the Voyagers' trajectories based on 1993 calculation
define reference telemetry frequencies with adequate resolution
such that any difference to actual received telemetry frequencies
may be correlated to the Pioneer acceleration effect or anomaly?
Is this data archived in any manner for current or future analysis?
