It is proposed that adopting the CSR BlueCore chip to establish the intra-satellite Ad Hoc network

to realize wireless data transmission between peripherals of the on-board integrationg electronic system.The performamce of BlueCore chip under space enviromnment is a key point in the design.High-low temperature test and electron beam irradiation experimental researches are carried out.The results show that the BlueCore chip can stand a-70

1

00℃ temperature range

and has a no-less than 26krad（Si） total dose tolerance.Some useful conclusions are reached

which can be taken as the reference for the satellite design and engineering application.
