GOCE is at 268 km.

1, If measurable prob. enough friction to cause failure to maintain orbit, but then has rocket(s).

2, It is designed to measure g since the earth moved g changed for that reason, no?  also would the atmospheric mass under the satellite change with the passage of sound?

"In the anacoustic zone above 160 kilometres (99 mi), the density is so low that molecular interactions are too infrequent to permit the transmission of sound."
