Quote from: Phillip Clark on 12/28/2016 08:48 amI seem to remember from descriptions many years ago that the second stage verniers were used for orbit circularisation.Well, this is not a separate burn, just a continuation of the 2nd stage main engine burn. See this from CZ-2D/JL-1 launch in 2015:

The GJ sats have a propulsion system. Is the orbit so off-nominal that using the propellant to raise the GJ sats orbit to its desired orbit is not possible and will significantly shorten its lifespan??

Is the orbit so off-nominal that using the propellant to raise the GJ sats orbit to its desired orbit is not possible and will significantly shorten its lifespan??Good question. 100 m/s is needed. Do we know the mass of the GJ sats? Only about 5 kg of prop per 100 kgof sat needed.
Chinaspaceflight says 570 +/- 20 kg for each
Here are tentatively the frequencies to try for monitoring BY70-1 before it reenters
BY70-1 - Bayi Kepu Weixing-1
